What Is Exposure In Photography And Its Rules

Digital SLR camera is available now in almost every household, but how to use it correctly, not everyone will be able to find out. If you are a beginner photographer, then this article is for you! Exposure in photography is the basics of professional photography. You cannot make any good frames, if you have no idea about what is exposure in photography. This is the first thing that photographers study. They just have to know the rules of exposure in photography. The parameters that are included in this concept, except at first glance, seem incredibly complex.

So, let’s see what the exhibition is in the pictures. How to avoid mistakes for novice photographers? First and foremost, the elementary terminology must be learned, because without it any instructions cannot be understood and advice from professional materials cannot be applied in practice.

what is exposure in photography

the conditions

Exposure in photography is a list of specific parameters, each of which is adjusted to the position in which the shot is made. Your tool, working through the lens, measures the amount of light coming in from the outside, and transmits commands to settings. Good light is a vital factor for a good photo.

Expo Parameters

Let us analyze the value of the exhibit parameters.

Aperture (f). In the lens of your device, there are thin petals (plastic or iron) that open and close the hole in the lens. The diaphragm limits the flow of light that passes through the lens. This value is marked with the letter f, and the next number will show a lower or higher value. There is such a thing as a diaphragm number. It is denoted by F / x. In this segment x is the focal length of the lens.

Excerpts. This parameter is measured in seconds and fractions of a second. Indicates the exposure time of a light beam for camera sensitive materials.

ISO sensitivity displays how the film or matrix reacts to light. The higher the number of ISO, the greater the light of the image.

Exposure in Photography How to Avoid Mistakes

White balance

One more important parameter in shooting is the white balance. BB is responsible for reproducing the colors on your frames. This is a complex parameter that you cannot touch during normal shooting. Enough autotning your tool.

It so happens that the photographer does not like delivery in frames. This means that you must set the white balance yourself. To do this, use a special gray card. If not there, then just take a picture from a blank sheet. In your gadget I will take it as a benchmark. There is another option, in the settings you can choose one of the options: cloudy, incandescent, daylight and so on.

From professionals, you can also hear the expressions of “exhibition” and “exposure triangle.”

The exhibition is side by side: the diaphragm and exposure. The exposure triangle is all three of the above parameters. You must be very careful about shooting in manual mode, because here you can set each parameter separately. You should know: change each of the parameters will be shown in the image.

Let’s play with the slot: the effect

What does this funny name mean? This is when the image appears to the person, and around it you see a blurred background, colored circuit diagrams, dots, snow, and colored stripes. The background looks great, nothing to distract from it. Bokeh effect is able to make a masterpiece out of the most boring photo! Let’s move on to practice.

Your optics settings

What, in principle, does the bokeh effect depend on? If you need to specifically get an effect, then you can not do without special filters that are simply put on the lens. To get the background just blurry, you’ll need to work on the tool’s settings.

The aperture. It plays the most important role here. The more petals open, the clearer the background will be. Hint! Be careful when installing the diaphragm that is more open. If one person in this photo was successful, most likely, well, then a group of people or buildings is likely to turn into blurring. The use of bokeh effect with mind, not everywhere is related.

Focal Length. The more it is, the more pronounced the effect will be. If your lens has a zoom lens, then simply twist its circuit.

The distance to the shooting subject. The closer you are to a person, the greater the possibility of a blurred background. Don’t overdo it, as the device still needs to focus. It is optimal if there is a distance of one meter between the person and the background. Then the background will become a masterpiece.

People, for whom photography is baking, get light lenses quickly to work. This is an expensive professional equipment, but with these lenses the bokeh effect is amazing.

Macro lenses and blur image lenses are also suitable for blurring. First needed to shoot very small things.

The effect and improvised materials

To create a blur effect, it is not necessary to purchase a lot of expensive filters and torture the camera with complicated settings. And many professionals benefit from improvised money. Maybe:

  • Polyethylene film;
  • Light fabric (chiffon, organza);
  • Scarves with an interesting pattern.

This stuff can be used as wallpaper. Do not forget: it is optimal that the distance between the background and the target is one meter.

There is another way to use cellophane package. Wrap around the lens, so there is a small gap that will fit the subject. You can tie the bag with small pieces of scotch tape.

Cut into pieces of organic glass, cardboard, orgelipta circle or other desired shape. This homemade filter will allow you to make unique photos, just fix it correctly on the lens. Fabric or scarves can also be placed on the edge of the lens for an extraordinary effect.

Exposure adjustment

Exposure in photography is very important. So let’s talk about setting it up. Each camera has its own hidden exposure alignment. In the manual, you will find how to properly use “hot keys” on the case. For example, in a Nikon mirror, you can use the Fn button to set the ISO. A wheel next to the screen will allow you to set the shutter speed. To adjust the aperture, you need to press a small button next to the shutter release button.

Semi-automatic modes of SLR cameras

To receive images with different exposures, you can choose one of the semi-automatic tool modes. This is an excellent option for beginners. By changing just one parameter from the top three, you will get the correct exposure in digital photography.

With a professional SLR camera manufactured by Canon, an icon on the TV wheel means shutter priority. AF is aperture priority.

Nikon Creative Modes:

  • M – manual mode.
  • P – semi-automatic mode.

Hint! Beginners should use the semi-automatic mode, with an emphasis on aperture priority or shutter speed. Manual mode will be difficult at first. Do not simplify your life and use the automatic settings. As practice shows, this is convenient, but at the time you will simply be too lazy to understand the settings and you will lose the opportunity to participate in creative photography.

The advice of professionals in this matter is very important, but excellent pictures will only come from you after you have practiced. Shoot as much as possible, successfully writing down the values ​​\ u200b \ u200bof the specified parameters, as well as the indicators that should be avoided.

Hint! Do not ignore the tool’s instructions. This knowledge will give you the opportunity to make excellent employees.

Exposure scale

Exposure scale is the parameter that will indicate to you, how correctly to set the triangle values. Find the exposure level indicator on your camera using the instructions. Look at it. Have values ​​shifted to the right? The image will be very light. When running left – overexpose. The correct exposure in photography is when the mark stands at zero.

Exposure volume can also be adjusted manually. If the exposure compensation is at zero, and the image is not bright or dark, then play with the cursor slider.

Exposure metering in photos (media)

There are three exposure modes in the image. This matrix, point, and weighted average. Let’s look at each of them:

The matrix is ​​also called multi-valued, evaluative, or multusym. In this mode, the camera will measure the exposure in the image itself. To work, you need uniform lighting. This is the most hassle free mode.

Weighted position. Placement makes the measurement in the center. And the edges of the image are still far from working. Excellent placement for working with portraits.

the point. The most difficult situation. A newcomer could not handle it. Similar to the previous one, but only 5% of the image is measured. For work, it is necessary that the subject matter be well lit and contrasted.

Exposure routes

The types of measurement have been listed above, but everyone has a major drawback. The result is slightly dependent on lighting, it only affects the shooting object. For example, take two dishes with vegetables. One of them will be orange, and the second – blue. The lighting in the room is the same, and the light falls evenly on the dishes. Use spot metering and find out the exposure value for each object. Interestingly, the blue plate has the lowest brightness, and the yellow one has the larger one. But if I understand, then it should not be so, because the conditions of the lighting objects are the same.

How does light affect the measurement

The reason for these differences in exposure is to match lighting conditions – in the reflectivity of different colors. You can keep looking and change the dishes to black and white. The lighting should not change at the same time. Naturally, exposure to black plate is needed more than white plates. Conclusion: With the measurement system, the intensity of light is not taken into account, but rather its reflective properties.

Exposure in the smartphone camera

Understanding exhibition in photography means getting great pictures on any instrument! Modern smartphones are equipped with a beautiful camera, and often the images are obtained no worse than a professional camera. The portability of the device is also a huge plus, since it is not always possible to carry a bulky mirror tool.

Unfortunately, it is almost impossible to influence the exposure in the built-in camera. The built-in function itself performs measurements and distribution of the light flux.

Jonat L. “Exhibition in Photography”

In the book we talk about positioning the exhibition as a creative process. The author tells of hijacking how close this process is to art, because he’s far from a boring set of benchmarks!

In the book “Exhibition in Photography” Gunt talks about that, with correctly selected parameters, the main thing is that the tonality of the image is respected. White and black colors should be clean, and intermediate shades should not be distorted.

What will the book teach? ”The writer tells you that correct exposure in the image is the decision about which key to give to the image. This book will help you understand how important the exhibition is to photography. How to avoid mistakes in this matter, will tell the famous author of the book.

Getting to know the capabilities of your camera.When a person takes a mirror camera and begins to understand the settings, the most difficult stage is the study of the basics of exposure in photography. After dealing with this issue, you will be a step closer to the art of professional photography.

From this article, you learned what information you can see in a viewfinder and camera and how to properly use it for shooting with the correct exposure. Having purchased the complex equipment, which is a mirror camera, you must learn the instructions as a mantra.
