Avatar refers to portraits above the shoulders or pictures only used for identification on websites and social platforms.
Shoot an avatar
When taking an avatar, you should not only take some lively personality expressions. A more formal photo similar to the ID photo style is definitely essential. On the one hand, taking this photo can turn on some built-in grid functions of the camera and make it horizontal and vertical, which makes it look more formal.
Exposure skill
If it is a fully automatic digital camera, you can use the portrait mode that is usually preset inside the camera. In this way, the camera will give a shooting parameter suitable for portrait shooting according to the original preset, so the portrait will be better.
Shooting skill
It is best to shoot at the same position as the photographer's glasses, so that the head shot will not appear perspective distortion. But if this face is fat, you can shoot it from a slightly higher position, or you can ask him to nod his head a little lower, so that the shot can make the subject look thinner.
