What problems should we pay attention to in advance when buying art photos?

Call the merchant in advance to make an appointment to take photos. Don't drink water the night before, lest your eyes swell. Go to the photo studio without makeup. Don't draw anything. Don't use some facial cleanser. Wash your hair in advance. Don't use qualitative things such as gel. Do not wear dark underwear. The armpit hair is best cleaned. If you go to a group ticket, you'd better ask what it contains, including false eyelashes and face money for makeup. You should also ask how many negatives you want to send to an album, and add as many as you choose (personal advice is not to choose more than one).
