When taking headshots, in addition to taking some lively personality expressions. A more formal photo similar to the ID photo style is definitely essential. When taking this kind of photos, on the one hand, you can turn on the built-in grid function of some cameras and make the photos horizontal and vertical, so that the photos can appear more formal.

You can use the horizontal line of the glasses, the horizontal line of the ears, and the mouth and nose as reference objects for adjustment. And when shooting, you can enlarge the viewfinder as much as possible to leave more background, which leaves more room for post-processing.
