Taking a camera in hand, first of all, let's pay attention to how it behaves in different conditions. The same can be done with a smartphone. When shooting indoors, opposite the window, you may notice that the subject will be darker than the light outside the window. Ideally, the camera should set such parameters that everything that is outside the window will be overexposed, and the subject being shot will be able to be seen.

This is how light metering works with a camera, and it is precisely such a program that is incorporated into it. The camera always tries (like a camera in a smartphone) to set such parameters in order to average out the light and shadow, and bring the picture to program zero - when the areas of light and shadow are evenly distributed over the image. The picture turns out to be flat, but it turns out. When we try to shoot a dark object against a lighter background, this background will be blown out to get the correct picture according to the camera. However, if we move the camera to the side, we will find that the background acquires details and does not light up anymore, and the subject, which remains a little on our side, has become too dark.

The thing is that modern cameras have no idea what we want from them when we shoot this or that photo. They are guided by the readings of their sensors, thereby setting the parameters according to the registered light intensity. The logic is simple: if it is too bright around, I will try to make it so as to line up zero, using all the mechanisms available to me. Thus, the camera will try to align the predicted light entering the matrix to a certain "zero" value, and will make the photo darker if the surrounding lighting is too bright to get a normally illuminated frame.

In the event that it is too dark around, the camera, on the contrary, will try to lighten the picture so as to bring it closer to zero. Somehow not quite flexible. To do this, we came up with a lot of compensation settings, and of course we will talk about them further. Until then, practice.

Put your friend, comrade, or cat in front of the window. Try taking a photo so that you can get more detail outside the window at the same time without darkening your friend's face. And then try the opposite - stand with your back to the window and photograph the subject using the light from the window. Compare the results.
