I have searched, and have really found nothing into this specific type of situation.
I was contacted by a mother to take senior pictures for her son and his girlfriend, as well as some "engagementish" pictures on the same day and same location. I gave her the price for the session, which might I add is very affordable for the area. She agreed to the price, and we set a date.
The date comes, she informs me that she is sick and wont make it to the shoot. So the guy and girl show up with the girl's mom and the shoot goes on for around 2 and a half to 3 hours. It went really well, and the kids seemed to enjoy themselves. I told them i took around 300, but that quite a few would be pull backs and test shots.
I edit them, delete all the trash, and get about 45 for each kid. I post them online and I get a call from the boys mother saying that she hopes that this isnt all of the images, because the other mother mentioned 300 images.
Is it too crazy to return 45 images to a customer fully edited and varying in locations and poses?
Let me know if I am totally out of line with my number of images.
Thanks guys.
I find that by being honest and using the word "fraction" I am not committing to a specific number and they get what they get.
