Modern optics allows you to improve your characteristics when creating, which, in turn, allow you not only to observe the macrocosm, but also to take photos for later study.

Macro photography of the human body is very exciting, it became available relatively recently, but has already managed to give the world of science extremely useful information and better understand the structure of various tissues of the human body.

Cochlea of ​​the inner ear

Cochlea of ​​the inner ear: a red spiral band is the main sound-sensitive membrane that transmits signals to the organ of Corti.

Filiform and fungiform papillae of the tongue

Here, among the filiform papillae, a round papilla is visible - a receptor that reacts to salt.

The filiform papillae of the tongue, they are rough and keratinized, belong to the mechanical receptors. By the way, the muscles of the tongue are the strongest in the body.

Epidermis and hair of the human face. About 600,000 epidermal flakes are shed every hour.

An image of the human epidermis obtained using a scanning electron microscope. In about 27 days, the surface layer of human skin is completely renewed.

This is nothing more than the tip of a human hair under magnification. An even cut of the hair is obtained when using a razor, in the case of using scissors or an electric razor, the end of the hair is significantly damaged. Hair does not decompose and rot for a very long time - Egyptian hair, which for at least 4 thousand years was with perfectly preserved hairline.

Image of the surface of a broken human tooth. The green part is bacterial plaque, and the uneven sawtooth surface is tooth enamel.

Macrostructure of the leg bone

Internal structure of the leg bone. By the way, in the human feet there are more than 50 bones, and in total in an adult there are 206.

Papillary pattern of the finger - papillary lines and sweat droplets secreted by the pores are clearly visible. By the way, the pattern of fingerprints differs even among twins.

When viewing the pictures, it seems that we have entered another world and look at it through the eyes of a certain bacterium. Everything in Everyday life it seems to us scanty and insignificant in the macrocosm, it turns into something gigantic, sometimes nothing similar to the human eye. In fact, if you look down, it's no less fascinating than looking at the stars in space. Although humanity is more inclined to aspire to look into something distant, global and infinite like the universe.

Features of macro photography of wildlife

The solution to this problem is the most interesting, but at the same time especially difficult, since the objects of the survey (insects, freshwater, etc.) can be in motion and you need to select the right moment.

It is very difficult not to frighten off the “bug”, as you need to get very close to it.

Here the subject is in a stationary state and the problem described above is not worth it, but there are some nuances. You need to take care of the background and lighting. For example, make a homemade "light box", which will be described later.

This topic involves describing and illustrating various lighting techniques, choosing the depth of field of an image when various types macro photography.

As a result, it is expected to obtain beautiful macro shots of good quality that will be of interest to the viewer. I would also like to develop my own style and find my own zest in macro photography. I hope that I will succeed and my work will be appreciated.

Macro photography and its technology

Picture 1

Macro photography is one of the most interesting genres of photography, giving maximum scope for creativity. With a macro lens, you can take a fresh look at ordinary objects, interpret them in a completely different way, experiment with the position of the subject and light.

The two most common and most obvious mistakes are shooting in bright sunlight and shooting with direct flash. Therefore, backlighting is needed, but you need to consider the design of reflectors and / or diffusers that would soften the direct light of the sun or flash. A well-chosen backlight does not attract attention, slightly differs from natural light, does not form or almost does not form glare. But at the same time, it allows you to significantly improve the quality of the image. How and from what to make flash attachments - you can fantasize a lot, there are countless options, from various improvised materials. If only the light suited.

Proper lighting plays a crucial role in macro photography. You can use a flash, but diffused light is better. To begin with, it is better to take pictures in conditions natural light. You can also build a simple photo studio using artificial light sources that everyone has at home. But in this case, it is not recommended to use lamps with harsh light: unpleasant shadows will turn out in the picture, and the photo will have to be edited for a long time in graphics programs. You should not use the built-in flash when shooting macro: this way the object will turn out to be overexposed, ugly color shades will appear. To avoid this, you need to use natural lighting and reflectors, varying the location of which, you can choose the optimal lighting. Specialized macro flashes, such as those shown in the photograph (Figure 1), are much more convenient to use. The location of the emitters directly on the lens, almost shadowless lighting - very convenient for technical shooting. Having installed it on the camera, we get a fairly compact and easy-to-use design. In addition to special lighting devices for macro photography, there is a large selection of attachments and attachments for lenses.

In addition to attachment lenses in various modifications that can be used with both rangefinder and compact cameras, here it becomes possible to use extension rings and fur, a teleconverter, and also put the lens in an inverted position.

A special case of attached lenses is multi-lens attachments and the use of an additional lens in an inverted position. As an example, a photograph is shown where the Nikkor 28 / 2.8 lens is installed upside down on the main Sigma 28-70 / 2.8-4 lens (Figure 2). You can shoot with this pair only at a focal length of 70 mm of the main lens - otherwise we get strong vignetting. The shooting scale is approximately 2:1. The use of an additional lens is common enough in macro photography to achieve high magnification. It is convenient that you can assemble the kit from improvised materials - from almost any pair of lenses available. Nevertheless, this scheme has enough shortcomings - the number of lenses increases very much, respectively, reflections / refractions / scattering inside the optical system increase. But the main disadvantage is the low luminosity. Indeed, in this case, the rear lens of the second objective becomes the front lens, the diameter of which is always small. This limits the use of such a scheme on SLR cameras, it is very difficult to focus on the resulting dark system. Much more widely, such a device is used by owners of digital compacts.

Figure 2

Figure 3

Using the lens upside down is a great way to improve macro photography, especially if you don't have a dedicated macro lens. Any lens can be put in an inverted position, while obtaining a sufficiently large magnification - usually about 1:1.5 - 1:2 for standard lenses. For example, the photograph shows a Nikkor 60 / 2.8 Micro lens installed in an inverted position (Figure 3)

What is it for? - When shooting at a scale of 1:1 or larger, the optical properties of the lens are greatly improved if the lens is turned upside down. Moreover, this also applies to macro lenses, when shooting at a scale greater than 1: 1, it is advisable to turn them over. By itself, the inverted lens does not provide a large increase, so it must be used in conjunction with extension rings or fur - then it is possible to obtain the maximum scale in macro photography of 10:1 (Figure 4). This, of course, is a very conditional division, but it is generally accepted that up to a scale of 10: 1 - macro photography, and larger - already micro photography, which must be done with a microscope. Using the lens upside down makes shooting difficult. Autofocus does not work, the jumping aperture does not work, the aperture value is not transmitted to the camera. Only manual control is possible. There are special attachments that somewhat facilitate the shooting process - but still, using the lens in an inverted position is desirable only when it is really impossible to do without it. Especially considering that the rear lens and the entire complex mechanism for connecting the lens to the camera are directed forward in this case. With careless handling, all this is easy to damage and contaminate.

Figure 4 (extension rings)

Wrap rings are produced by manufacturers for their cameras, but you can use third-party products - it will be much cheaper. Here is a brief overview of specialized macro photography equipment that pushes the boundaries of macro photography.

As for the very technique of shooting and using the camera, the following should be noted: The successful use of such a technique as changing the depth of field can transform even the most ordinary object, give it certainty or emphasize a specific detail. In order to control the depth of field, you need to select the aperture priority mode on the camera. The smaller the f-number, the clearer all areas of the image are.

Conversely, to blur objects surrounding the main subject, which is in the center of the frame, you need to increase the aperture value.

In this mode, the camera automatically compensates for the large aperture, and the picture will not come out blurry or overexposed. You can also use the "Macro" mode, but I like the first option better. Since the macro mode is a fully automatic option, which does not allow you to choose aperture and shutter speed, thereby limiting the creative approach to shooting. Also, when using scene programs, the camera may make mistakes and not give the required results.

Let's return to lighting, since light is the most important visual means of macro photography, revealing the contour shape and texture of the surface of the object being photographed.

In each specific case, you need to find the most suitable look lighting, on which the expressiveness of the frame will depend. Macro photography can be done in natural and artificial light. The only source of natural light for filming is the sun. Despite the high illumination created by the sun on the subject, its high actinicity, that is, the effect on photographic materials, the use of solar lighting in some cases is difficult.

A strong change in illumination, depending on the time of day, year, geographical location, cloudiness, leads to the fact that the replacement of the natural illumination of the object, where possible, with artificial leads to best results. But it must be remembered that when an object is illuminated by one source, a sharp division into lights and shadows is characteristic. The use of several light sources leads to a decrease in the contrast between light and shadow, to the development of details in the shadows, that is, to an improvement in the transfer of the volume and texture of the object.

Figure 5

Illumination of objects during macro shooting aims not only to create the necessary illumination for obtaining a normally exposed negative, but also to reveal the shape and texture of the surface of the object being photographed with maximum expressiveness.

Macro objects can be divided into two main groups: opaque objects and translucent objects. Opaque objects whose surface areas reflect varying amounts of light falling on them. This group includes most of the items that you have to deal with in macro photography. Reflectivity depends on the nature of the subject being photographed, as well as on the structure of the surface. Surfaces are usually divided into matte (diffuse), glossy and mirror.

Translucent objects, passing through which the light is attenuated and scattered depending on the optical properties of the object, creating on the photographic material different optical densities of the image of the object being photographed.

As with normal shooting, the lighting of macro photography objects can be natural (daylight) with the use of backlights using reflectors and artificial lighting. Lighting can be subdivided by type into frontal, side to sliding, rear (through) and combined.

The practice of photography allows us to distinguish three main or most characteristic plans: general, medium and large. One of the effective techniques of a creative photographer is shooting very close-up (for example, the image of individual parts of a human face: eyes, lips, etc.). In the glossary of technical terms, close-up shooting means shooting at a scale of 1:2 or more, that is, when the object is reduced by no more than two times. Macro photography can also be defined as a direction of photorealism, distinguishing feature which is a selection of objects that are small in size and have a shallow depth of field.

The task of the photographer is to try to get pictures, looking at which you can see the details invisible to the naked eye. The value and usefulness of this type of shooting is difficult to overestimate.

Even a novice amateur photographer will use it to open new world, noticeable if you carefully look at the small components of nature (insects, flowers, moss, etc.).

The frames shot in this way will not leave the viewer indifferent. This is a kind of Gulliver's journey to another dimension, living its own life.

Macro photography is almost no different from ordinary photography: we focus, measure the illumination, set the aperture, shutter speed and shoot. However, it has its own nuances. As you have probably already seen, photography is an interesting, but very painstaking work in which all the little things matter. When taking macro shots of live objects, remember Golden Rule: everything that can fly will try to fly away at the most inopportune moment, everything that crawls will crawl away, everything that jumps will jump away. You need to be ready for this!

Figure 6

An object illuminated by ambient light. Macro photography at home using a translucent tent

Figure 7

To soften and neutralize unnecessary shadows and highlights, professionals advise using a translucent "tent" - a light box that resembles a cube in shape, the walls of which are made of translucent white material. Such a "tent" also allows you to create the effect of a three-dimensional image of the object being filmed, highlighting the objects from any side (Figure 7).

Of course, macro photography has its own characteristics. Due to the fact that the camera optics are not ideal, when shooting close, that is, in macro mode, some significant and not very (depending on the camera class) geometric distortions will be observed. This means that if you photograph a student's notebook, for example, then you get by no means perfect squares and not quite straight lines. By the way, jewelry is not recommended to shoot close up precisely because of these distortions, but we will find a lot of other interesting things that can be clicked from close distances. If, under the same lighting, when there is not very much light, an ordinary photo comes out without "stirring" and blurring, then with macro photography there is a very high risk of getting a not too clear photo. Another fuzzy photo can be obtained if you focus on something close and slightly (literally a few centimeters) take the camera in any direction. But this may not bring inconvenience if you learn to press the shutter button immediately after focusing.

If you want to shoot wildlife, you should always have a few ponds in mind. The water attracts wildlife and it is easy to find frogs there. You can even look for a pond with floating duckweed, from which the heads of these amphibians stick out.fujifilmS5,TamronSP 180mmF/3.5Di 1:1 Macro. Exposure: 13 s., ƒ/16,ISO100.

Mastering the art of macro photography and close-up nature photography takes time and patience, but knowing the answers to the questions “when?”, “where?”, “how?” increase your chances of finding amazing subjects by creating a successful shot. For photographers with limited travel time or budget, close-up photography opens up unlimited opportunities for shooting around and inside the home. There are four parks within a 20-minute walk of me that are teeming with great subjects, and my garden has flowers and plants that attract butterflies, dragonflies, and other small critters. All you need is some gas, a park pass, and a book that can identify the subjects you've chosen to shoot.

Throughout the four seasons, the life cycle of flowers, plants and insects varies by month and sometimes by day. Interest is not only the process of photography, but also the study of the constantly changing environment. If it is not possible to go outside, you can study the nature of your region, delving even more into this activity.

Our hobbies are often limited by work schedules and family activities, making it difficult to set aside time for filming. Working with macro photography, you can take pictures at any time of the day. Unlike wildlife and landscape photographers, who are often tied to perfect light in the early morning and late evening, macro photography enthusiasts can effectively control the available light, regardless of the time of day, using diffusers and reflectors.

When to shoot

With the environment constantly changing throughout the year, we have an amazing variety of subjects to shoot with. The tiny landscapes of the macro world change each other at an astounding rate, so knowing when to be in nature is the key to success. Spring gives us forest primroses, and open fields - tall summer and autumn flowers. Some wild flowers can bloom for a long time, while others last only a few days or open only at certain hours.

Flowers are the most popular subject for macro photography due to the fact that they are common and easy to find. Walk through wooded spring countryside as well as open summer or fall fields.NikonD7000,TamronSP90mmF/2.8Di 1:1 Macro. Exposure: 1/60 s., ƒ/22,ISO 3200.

Books about life cycles flowers, plants and insects in your area contain useful information about nature's "schedule" that will allow you to be in the right place at the right time. There are also various online resources and sites of local conservation centers where you can find something worthwhile. Another option is to contact the local environmental organization and get answers to all your questions.

Seasonal cycles for wild flowers, plants, and insects can vary by location. For example, in Michigan, the fall color starts at the upper peninsula and ends at the lower northern, followed by the southern lower peninsula. If you contact local nature photographers, you can get similar information for your region.

For example, on a cool summer morning when the temperature fluctuates between five and six degrees, dragonflies and butterflies freeze as their body temperature drops. Therefore, they will not fly away if you get close and set up a tripod to shoot. Just find a field that has a lot of the right insects during the day, and then go there on a cold morning and carefully look for them in the tall grass.

In my northern region ( we are talking about the state of Michigan, where the author lives - approx. translator) with the onset of December, an ice crust begins to form around the banks of small flattering channels, creating stunning abstract patterns, but as the ice thickens, these patterns disappear and the ice turns white. Knowing the "natural timetable" in your area will increase your chances of success.

Where to shoot

Knowing where to shoot is just as important as knowing when to shoot. I traveled a lot for my business and almost anywhere I could find a local park, conservation center or botanical garden to shoot in. Wherever you live, there should be places to take pictures. If you do not know the area well, use the Internet to find a suitable place.

Leaves are a great subject that photographers often forget about. Autumn is the perfect time, because at this time the leaves take on an amazing color.fujifilmS5,TamronSP 180mmF/3.5Di 1:1 Macro. Exposure: 1/16 s., ƒ/16,ISO 1250.

The best way to learn about shooting locations is to set aside a day or two to explore the local forests and fields. A detailed journal that marks places with interesting subjects will be a useful tool for the future. I have studied various places around me, so I know when and where flowers, plants and insects appear.

I also pay attention to feathers, bits of shell, and patterns in the sand created by the wind. The swampy area has a unique flora and the ponds attract animals such as frogs, turtles and dragonflies. The open fields are teeming with insects, which are ideal for photographing with a macro lens. Flowers can be found anywhere. If you are lucky enough to live near the botanical garden, you can find a huge variety of flowers and plants from different ecosystems. Sometimes botanical gardens are equipped with greenhouses, allowing you to shoot in any weather, and some even have both indoor and outdoor areas.

How to shoot

Macro photography and close-ups are very different from other forms of nature photography, as the subjects are a few centimeters away from the lens. Any digital camera is suitable for macro photography. My most successful photo was taken way back in 2004 with a 6 megapixel Fujifilm S2 - by the standards of the digital world, that was several generations ago.

It is very important to choose the right macro lens for the right subject. True macros have a fixed focal length and a 1:1 magnification ratio, which, when shot from a close distance, can reflect the actual size of the subject in the picture. The most common macro lens focal lengths range between 60mm and 180mm. Lightweight and compact 60mm lenses are good for shooting handheld or when working with stationary subjects, but because they are only suitable for short distances, forcing you to get very close, they are completely unsuitable for shooting living creatures, because they will simply fly away.

If you don't live in a desert area, take a look at the botanical gardens in the area, which have greenhouses with tropical and desert plants. Succulents are great subjects because of their artistic patterns.NikonD7000,Tamron 16-300mmf/3.5-6.3DiIIVCPZD. Exposure: 1/13 s., ƒ/16,ISO400.

Medium focal length lenses (90mm) like the one I use are a good all-around option that can handle most situations. It blurs the background perfectly when shooting flowers and beetles. When it comes to telemacro lenses, the most popular option is 180mm. This view provides the maximum working distance between the photographer and the subject, making it ideal for photographing living creatures or distant objects.

Over the past few years, optical manufacturers have begun to produce wide-angle lenses with macro functionality. I use Tamron 16-300mm which allows me to use 16mm if I want to show surrounding nature and 300mm for shooting distant subjects such as frogs in a pond or ice around a stream bank. These lenses aren't true 1:1 macro lenses, but with each generation they get closer to that standard. For example, Tamron 16-300mm has a ratio of 1:2.7. This means it will be able to capture an area as small as 1.5 x 2.5 inches (3.81 x 6.35 cm), working for 90% of macro photography.

When I ask macro photographers what they have trouble with, the answer is always the same - depth of field, or how much of the subject is in focus. Which aperture to choose in order to focus correctly is always a test. For cases where the whole composition is interesting and every part is full of detail, I set the aperture in the range from ƒ/22 to ƒ/32. Most of the pictures in my portfolio are made in this style. If I want only a small part of the subject to be sharp and everything else to be blurry, I choose an aperture of ƒ/2.8 to ƒ/8.

To be sure how much depth of field affects the focus of a shot, photograph the same subject at different apertures, and then analyze the effect of each. As a little hint, you can remember that a larger f-number means more in focus, and a smaller one means the opposite.

To capture a dragonfly's wing, get out on a cool summer morning and look closely in the long grass. The cold will lower the dragonfly's body temperature so it can't fly, allowing it to get closer and take a picture.fujifilmS5,TamronSP 180mmF/3.5Di 1:1 Macro. Exposure: 0.8 s., ƒ/32,ISO 125.

Aperture control is one of the most important parts of macro photography. You can adjust it in Manual mode or with Aperture Priority. Working with the first one, you also need to select the shutter speed, so if you are not quite sure you can set a suitable value, Aperture Priority will do everything by itself. Both methods work equally well, but make sure you adjust the aperture yourself.

When shooting macro, we are working very close, so for sharp shots it is critical that the camera is stable. I always use a tripod. I know a few handheld photographers, but not everyone can hold the camera steady for long periods of time. In terms of lighting, I never use a flash, 95% of my photos are taken with only natural light, but there was one rare case where I resorted to a small LED lamp.

Digital macro photography is a fascinating, exciting, fun and popular genre. Photos taken in this way stand out from all other images, because it is always interesting to see details that were previously invisible due to their size. Ever since W.H. Walmsley (W.H. Walmsley) first proposed the term "macro" to his colleagues, a lot of time has passed, but its essence has not changed.

Macro photography is the art of photographing extremely small objects so that they can be clearly seen. In the role of "models" are flowers, insects, any small objects. The age-old question that haunts the minds of photographers is how to determine whether your shooting is macro or not? It is defined as follows: by the ratio of scales (1:1, 1:2 and so on) and the so-called maximum reproduction ratio (MMR). It means the largest possible percentage of increase compared to the actual size of the object that the camera can offer.

There are many types of macro lenses, and they have varying zoom ratios. For example, a 1:1 model will provide an image with more detail and better resolution than 1:2 or higher. Experts take such lenses as a standard. However, the general public calls macro photography any camera capable of producing close-up images.

Here are 10 little tricks and useful tips, which will help to improve in an interesting and entertaining genre.

Choose the right camera

Almost all cameras, even in mobile phones, are equipped with a special macro mode. But, if you plan to fully work in the genre, change the approach to choosing equipment. To get serious about macro photography, you'll need a dedicated macro lens and DSLR equipment capable of rendering 1:1, life-size images. There are several methods, which we will describe below.

Modern digital cameras have highly sensitive sensors. This provides many options that help you control the progress of the shooting. If you don't have a DSLR, it's definitely worth getting one.

Find the right lens

Macro photography is a genre in which the quality of the lens is more important than the parameters of the camera. A true macro lens is a 1:1 magnification device, but there are impressive 1:5 models on the market (eg Canon MP-E 65mm F/2.8 1-5x Macro Lens). This means that you can increase the size of the image up to five times the original size. In particular, if you want to capture detail in a snowflake, you need something better than the traditional 1:1 zoom technique that most macro lenses support.

In pictures taken with cameras with full frame sensors, a 4mm ice crystal will only take up 2% of the frame, more "filling" will be required. Thus, a 1:1 lens is not enough to capture something more complex than a small standard subject. You can use additional accessories with it - such as extension macro rings.

Using macro rings

Macro rings are hollow tubes that are fixed between the lens and the camera, increasing the distance. So the front element of the structure will be as close as possible to the subject, which means that the increase will become large. If it is not possible to use a special macro lens (finances do not allow), rings are a good replacement. However, they also have disadvantages - first of all, light loss, depending on the length of the device. Macro rings with one segment - about 12 mm, two - 20 mm. Depth of field decreases as you get closer to your subject, making it harder to get a result in focus. The "electrical" connection between the lens and the camera disappears, and autofocus becomes unusable. But you should know that in any case, with a macro ring, the result is better than with a standard zoom.

macro photography example

Close-up filters

Close-Up - close-up filters. Their action can be compared to the work of a magnifying glass. They scale the object, but the quality of the image is somewhat reduced, as is the amount of light hitting the lens. Filters are inexpensive and will be a good help for fun experiments if you don't have a macro lens. For them, there is a gradation: +1, +2, +5, and so on, the larger the number, the more the filters increase, and the less light hits the sensors.

Flashes: External Flash or Ring

Regarding macro lens: good 1:1 models are Nikon 105mm, Canon 100mm, Tamron 90mm. There are cheaper models, but then you have to get very close to the object. If you can't afford a full-frame camera, consider the Nikon (D5300, D7200), Canon 70D, or the more expensive Nikon D750, D810, or Canon 5D Mark III. In the end, the result depends only on you - improve, experiment and continue to search for beauty in small things.

Artem Kashkanov, 2019

Shooting small objects close-up is almost an integral part of the creativity of any photographer. It can be anything - flowers and butterflies, wedding rings at a wedding, manicure and pedicure samples, product photography for an online store, and so on. How best to do this - and will be the topic of this article. There is a misconception that macro photography- a very simple genre of photography or, even, is not a genre at all. All that is required for this from the camera is the ability to focus from a few centimeters on the subject. This formed the basis of the myth that soap dishes have significantly better macro capabilities than devices with interchangeable lenses.

Indeed, manufacturers of photographic equipment have achieved a clear progress in this - most compact cameras can focus from a distance of 1 centimeter or even less. But it turns out that this is not all that is needed in order to shoot macro with high quality. Especially soap dishes...

Scale

First of all, let's first understand what is macro photography and how it differs from close-up shots. It is believed that the border between macro and close-up passes at a scale of 1: 2. In general, what is the scale in macro photography? After all, this value is almost always indicated in the characteristics of the lens. Its meaning is simple. At a scale of 1:2, two "linear" millimeters of the object are projected onto one "linear" millimeter of the matrix. That is, if the device has a 22*17 mm matrix (a typical value for cropped pinholes) and a lens that allows you to shoot at a scale of 1:2, then a coin with a diameter of 17 mm will be projected into a circle with a diameter of 17/2=8.5 millimeters, that is, according to height will be half a frame. If the lens can give a scale of 1: 1, then the coin will turn out to be the height of the entire frame (if the matrix is ​​APS-C).

Based on this, we come to the conclusion that the main indicator of the macro capabilities of the lens is not the minimum focusing distance, but the macro scale. With the same shooting scale, different lenses can have completely different focusing distances - from 20 centimeters to 1.5 meters or more. Why is that?

Focal length, focusing distance, perspective

We know that one of the main characteristics of a lens is its focal length. The larger it is, the smaller the angle of view of the lens and the more it "brings" the object. Accordingly, the stronger the lens "zooms in", the greater the distance it can provide shooting at the required scale. The most typical focal lengths for macro lenses range from 50mm to 180mm. What is the difference between these lenses if they give the same macro scale? It's all about transmission perspectives. It is known that the closer the photograph is taken, the more the image of the object is subject to perspective distortions. Below is an example in which the same object is photographed at approximately the same scale, but with different focal lengths. For simplicity, a rectangular object is used:

The difference is obvious! If when shooting from a long distance with a long-focus lens, a rectangular object retained its shape, then when shooting with a wide-angle lens at the same scale, we got significant perspective distortions, uneven lighting (due to the fact that the flash was too far from the lens), a high probability of hitting the frame of extra objects in the background. There is a rule in photography - in order to prevent the appearance of noticeable perspective distortions, you need to photograph an object from a distance of at least 10 times greater than the "depth" of the object. That is, if we photograph an object 10 cm in size, then we need to do this at least from a meter distance. The focal length of the lens must be such as to provide the desired zoom without approaching the object closer than this critical distance.

How is a macro lens different from a normal lens?

A lens that has the word Macro in its marking usually has the following features:

• Increased focal length. Most macro lenses are moderate telephoto lenses. A telephoto lens hardly distorts the proportions of objects. The more critical the issue of transferring the shape of an object, the greater the focal length (and, accordingly, the focusing distance) should be.
• Larger Macro Zoom than Conventional Lenses. If for a standard "fifty kopeck" Canon 50mm 1:1.4 the scale is 1:4, then for CANON EF 50 mm f/2.5 Compact Macro it is 1:2, that is, it allows you to photograph an object 2 times larger. Macro zoom can be determined by either the minimum focusing distance or the focal length. Macro lenses with a long focal length (150-180 mm) allow you to shoot an object from a greater distance (important for shooting, for example, shy butterflies) and more "stretch" and blur the background.
• Aperture range shifted towards small apertures. If for most conventional lenses the aperture can be clamped to 22, then the macro lens allows you to do this up to 36 and even 45. This is done to provide a larger depth of field zone, since when shooting at close range, even at f / 22, the depth of field is a few millimeters.
• The optical design is optimized for shooting close objects. Any optics has distortions (aberrations) - chromatic, spherical, coma, astigmatism, which adversely affect the quality of the picture. When zooming and focusing, the lenses move inside the lens, and the optics manufacturer needs to compensate for aberrations over the entire zoom / focus range. In macro lenses, focusing in the foreground is preferred. That is why such macro lenses give "razor" sharpness in the portrait and draw the skin in all details, often emphasizing its defects. For this reason, many photographers do not recommend using a macro lens for a portrait - softness is valued in a portrait, especially a woman's.

Common macro photography problems

Loss of an object from the depth of field zone

The essence of the problem is that the photographed object is not completely sharp, but only partially:

The above example is just a strong crop of a photograph taken with a "regular" lens. When using a macro lens, the problem can be much more pronounced.

Suppose we have a 100 mm macro lens, aperture 1: 2.8, minimum focusing distance - 30 cm. If we try to shoot from the smallest possible distance with an open aperture, the depth of field will be less than 1 millimeter (calculated in the depth of field calculator, for full frame). Naturally, under such conditions, in most cases it is difficult to count on a successful photograph - the leading edge of the object will be sharp, the rest will rapidly go into the blur region. Of course, this can be part of a creative plan, but, for example, this approach is not acceptable for subject photography. The depth of field should correspond to the "depth" of the object. To increase the depth of field, cover the aperture. If you close the aperture to 45 (!!!), then the depth of field in this case will grow to 1.3 centimeters - this is quite acceptable for shooting a medium-sized object. But we know that when the aperture is clamped, shutter speed also increases proportionally. When clamping the aperture from f / 2.8 to f / 45, in order to maintain the exposure level, you need to increase the shutter speed by 256 (!!!) times. That is, instead of 1/250 of a second, it will take 1 second! Nothing to do without a tripod.

To check the depth of field, many cameras have an aperture repeater button. On Canon cameras, it is located on the left under the lens.

When this button is pressed, the aperture closes to the selected value. In this case, the picture in the viewfinder darkens, but at the same time you can see the real depth of field, which will turn out in the photo. In LiveView, this function is more convenient to use, since the picture on the screen is displayed with the same brightness.

If during normal shooting with a shutter speed of 1 / 20-1 / 50 seconds, the shake is expressed in image blur (“transverse” shake, it is partially compensated by the stabilizer), then with macro photography with a small depth of field, “longitudinal” shake is still possible - when the shutter button is stepped the unit accidentally moves closer to or further away from the subject. As a result, the subject either falls out of the depth of field (if the camera moves back), or the focus area is not where the photographer intended, for example, on the back of the subject. The most reliable remedy for macro photography is a tripod. It is practically a panacea for shooting stationary objects, the main thing is that its height allows you to properly position the camera. If you have to shoot moving objects, such as flowers swaying in the wind, here the easiest way out is to reduce the shutter speed to at least 1/250 second and burst shooting. According to the theory of probability, at least one out of 10 frames will turn out sharp.

Autofocus misses

Even if the lens does not have front / back focus, you should not rely 100% on the help of autofocus when shooting macro. Best to use manual focus in LiveView mode by turning on the focus area zoom. This alone guarantees that the entire object will be sharp, or that part of the object that we want to focus on will be sharp.

Normal flash does not illuminate the subject properly

When shooting from a short distance, flash parallax begins to make itself felt. The farther the flash is from the lens, the more uneven the lighting will be, as part of the subject may not be in the flash's range. Let's go back to the example above:

Although this is not macro photography, it is nevertheless easy to see that the flash illuminates the subject predominantly from the left. The right side of the photo is in shadow. To obtain uniform illumination during macro photography, special ring macro flashes are used:

Such flashes allow high-quality illumination of objects even at a minimum focusing distance, for example, like this:

lack of scale

Even a powerful macro lens is not always able to provide the desired zoom when shooting very small objects. In this case, you have to resort to the help of auxiliary equipment - a macroconverter, extension rings and more complex devices. A macro converter is a lens that is screwed in front of the lens and acts as a magnifying glass. Macro rings are placed between the lens and the body - while the focus area shifts towards shorter distances, that is, we can get closer to the object. You have to pay for this with a decrease in aperture ratio, the loss of the ability to focus on "infinity", a decrease in image quality due to aberrations is possible. However, it is possible to take very close-up shots even with a regular (non-macro) lens. An interesting article about the use of macro rings can be found on the website radojuva.com.ua

Is it possible to shoot a normal macro on a soap dish?

Let's digress for a while from devices with interchangeable lenses and turn our attention to soap dishes. The characteristics of most compact devices indicate the possibility of macro photography from 1-2 centimeters or even less. Yes, it looks tempting! In fact, it turns out that focusing at such a close distance is possible only in the wide-angle position of the lens. If you "add zoom", the macrozone is sharply moved into the distance and the scale decreases at the same time - I happened to hold many soap dishes in my hands, but they all had such a feature. What will come of it can be estimated from this "portrait" of a beetle, made on a Sony soap dish from a distance of about 1 cm (in wide angle):

It is noticeable that the proportions of the body of the insect are significantly distorted. And now let's see another photo of a beetle similar in size, but made using a device with a "large" matrix and a long-focus macro lens:

If in the first example the head of the beetle and its mustache seem huge compared to the body, then in the second the insect looks quite proportional. Also, due to the fact that the lens is wide-angle, extra semi-blurred objects in the background will often get into the frame. Here is the "masterpiece" own production I keep as an example how not to photograph macro.

This photo was taken in the early 2000s with an Olympus soap dish with a fixed wide angle lens. The minimum focusing distance was 10 cm. It seems that when shooting flowers 1 cm in size, there is no perspective distortion, but the background is just killer :) Thus, we can conclude that a good macro on a soap dish can theoretically be photographed if you can focus on a very close object is preserved over the entire range focal lengths. Unfortunately, I have not seen such devices yet. And now let's digress from macro photography and touch on the topic a little. subject shooting, since many are concerned about the question - how to make it qualitatively at home.

How to get by with improvised means in order to perform high-quality subject shooting?

I regularly need to photograph something for this site, but I don't have a macro lens, no ring flash, and no ambient light. The same situation regularly occurs with the owners of websites and online stores - you need to take a picture of some small object (for example, a product) so that this photo then fits into the design of the website. It is logical that for this the object must be on a uniform background, for example, in this way:

Or on a completely white background:

How do you think this car was photographed? Was a special box used for product photography? Or macro flash? Or some other "device" with an unpronounceable name? The following photo will probably make you smile:

Yes Yes! The white background is a sheet of an old calendar. A smooth bend makes the transition of the "floor" into the "wall" imperceptible. Another thing is that an external flash was installed on the camera, and its head was turned back. The back wall and part of the ceiling were used as a reflector. In this case, the softest and most uniform lighting is obtained, even better than from the ceiling.

Below is a table of the results of the experiment. Since my Canon 5D doesn't have a built in flash, I used an Olympus E-PM2. Then I took a DSLR and took a photo with a flash from the ceiling and from the back wall. See the results yourself.

Shooting with the built-in flash (Olympus E-PM2) It turned out badly - glare, reflections from shiny parts on the background, the image is "flat". Moreover, the aperture is not clamped, the depth of field is not enough (I shot it in auto mode).	Flash from the ceiling (Canon 5D + Canon Speedlite 430 EX II). Aperture 18. Already better, but the background is not evenly lit
Back wall flash (Canon 5D + Canon Speedlite 430 EX II) The background issue has been resolved. You can stop there!	Back wall flash (Canon 5D + Canon Speedlite 430 EX II), leveling adjustments in Photoshop And a completely white background is easy to make in Photoshop - either with levels, or with "color replacement".

What if there is no external flash? For lighting, you can use a regular table lamp. Only, it is desirable that a powerful energy-saving lamp with cold light (4000K) be screwed into it. Using "warm" light (2700K) for lighting can cause white balance problems. By moving the lamp relative to the object, you can achieve the optimal result so that the object is well lit and the shadows from it do not interfere.
