I haven't read your review, but personally, I think you have to be willing to take criticism-especially if you own your own business. I think critiques allow us a chance to better our business. After all, if no one provided honest feedback, how would someone be able to know their client felt their product/services weren't up to par? They would never have a chance to fix the problem, and the client would go on, not speaking highly of the product they received.
I hope it works out in the end and your photog won't continue to take it to that personal level.
