Maternity photos

Question about proper etiquette.

Are you suppose to tip your photographers? Like if you did maternity photo shoot or a newborn shoot do you tip the photographer? In my head the pics cost hundreds of dollars so why tip but I wasn’t sure what’s the proper etiquette if I’m suppose to and if I am how much?
