I have to pay upfront do you think it would be ok to tip when I actually see the photos??
I am a photographer! Usually, I do not get tips, but some people feel like doing it. If you are going through a studio, that's a little different. I have seen people do both! It really comes down to what you feel comfertable doing. I personally would never expect a tip from a client but would appritate it if I was given one.
