I'm not really sure where to ask this and I sort of scoured the forums. I know it's customary to tip photographers and any vendors for their assistance. We have engagement pictures on Saturday. The photographer volunteered two locations, both a little ways from each other. She's just starting out so her prices are pretty reasonable but again, she is just starting out and her pictures are very basic. I am not expecting a whole lot from them, TBH.
Anyway, what is the usual tip? 10%? 20%? Should we cover gas? Do photographers pay for their own parking if there is a fee?
Thanks
