Ugh, I had this happen early on =( One of my first sessions that wasn't with somebody I knew, was for a woman who had a baby boy. I did her maternity pictures for free, and her newborn pictures for gas money to drive to her home. Gave her a CD with all the edited pictures...and she did the same thing you're mentioning. >< I had a difficult time shooting her newborn, because it turned out to be a dark/stormy afternoon, and her house had NO light. At the time, I didn't have any extra lighting, I had always just used window light... So when I edited her session, I was scraping to even get 15 keepers. I took nearly 500 pictures!!!
Well.. I gave her the CD, and she emailed me later saying she was confused because she thought she'd get ALL the pictures..and what about the one we tried to fit in at the end where she asked all her hungry, grumpy, annoyed children to sit together "nicely" on the sofa with Mom and dad in the dark living room, all trying to squeeze in front of the narrow black fabric I had been using to pose baby on.
Well.. needless to say those pictures didn't turn out. And I explained my editing process to her. But in the end.. I realized I was at fault for not making clear to her what to expect. From her perspective, I was clicking away that camera button a mile a minute, and I was in her living room with the baby nearly four hours. To her, it doesn't make sense to explain how I could only get 15 "good" pictures from that..because to her eye, ANY picture of her precious newborn is "good." She said that she was upset because it felt like I was choosing which pictures she got and she "didn't get any say in it.."
So what I did.. was explain to her how my process worked, and apologize for not having been more clear in the beginning. I told her editing was a long process, and that it's not my policy to ever release original copies of my work. But that to help her, I'd be glad to let her at least *SEE* every original file, and choose a handful that I'd do my best to edit for her.
Keep in mind, this shoot went so badly, that even the 15 images I gave her, took nearly two hours EACH to edit decently. (I was also more slow with editing then, granted, but still.)
So.. I posted all 500 original images in a password protected gallery on my website...gave her the password.. and said I'd keep them up for two months.
Never heard back from her.
I still feel terrible about how that went.. But I learned a really important lesson. Since then, I have made it a point to tell every single person I take pictures for exactly what they can expect and how I go about editing. I explain that even if we take 10,000 pictures.. My goal is to get at least 20 or so to "turn out" to my standard. And that I do not release or show originals.
Honestly though.. I had a lot more people complain about this when I wasn't charging, or when I was charging next to nothing. After I started charging decent rates, people seemed MUCH happier with what they got lol.... Sure, my work was better by then, but it's true that people really do place much more value on something if they are actually investing in it.
Now, I don't release digital negatives *at all.* If people want copies of my work, they can order prints through me.. Or they can copy their small resolution watermarked files from the facebook page =P
Ok that was a novel! But I hope it helped a little. Best of luck.. it's so hard dealing with such nit-picky complaints on something you worked so hard to give somebody. It's so weird how people always push and push for as much as they can squeeze out of you sometimes. ><
