Why do you feel your face getting bigger when you take pictures or videos?

This is called "wide-angle distortion" in the eyes of photographers. Sitting farther away can really solve this problem. . Although it will appear that people are smaller and their faces are not clearly seen.

If there is a lens with a longer focal length, it will also be solved, but the focal lengths of the lenses of general cameras are very close, and there is little difference. .

You can use optical zoom when taking pictures. . Increasing the scaling factor can also solve this problem. Its essence is also to increase the focal length.

Similarly, if it is a SLR, it will be better to take a portrait with a focal length of 50MM, 85MM,135 mm.

Generally speaking, wide-angle distortion is easy to occur when shooting portraits with focal length less than 35MM. . .
