First, find a regular photography studio or wedding photography shop. On the whole, this photographer is excellent. If it happens to him, he won't work there. His reputation is the most important thing.
Second, try to choose location shooting instead of private photos. A closed space will make photographers have too many ideas. After all, just the two of you, male photographers have fantasies. Location shooting, there are many people, and it doesn't matter if the clothes are slightly exposed.
Third, if you choose a private photo, it is best to be with friends, at least two people, or it will work.
Fourth, choose a photographer to look at the face first. Although a person can't judge a book by its cover, at least he can see the photographer's eyes at a glance. Now look at his manners and see how his works are. Every photographer has different tastes, and private photographers can basically withstand the pressure.
Fifth, signing an agreement is not very useful, but before shooting, you should sign an agreement with the store and read the terms clearly. If there is an accident, compensation can be made.
