Does being a photographer require staying up late to work?

Look at what kind of photographer you are. If it is just a normal job in a photo studio, you must get off work according to normal off-duty hours, and few people will go out to take pictures at night. But this is not necessarily the case for people who have a photography hobby. Sometimes they need to take pictures of the stars or something like that. Speaking of staying up late, another situation is editing pictures, which is relatively rare in general.
