Take some for you....that have your artistic touch.
Take most for her. She is paying the bill. You may find you like the way things work out.
Far more difficult is the client that blames you because her child has the attention span of a butterfly. With mom standing behind you yelling, Betty, Betty, Betty, Betty, Betty, look at me, look at me, look at me. Well...the kid did look at her and never at the camera. I didn't have one shot with the child looking at the camera. The child was so mobile that I had to shoot handheld (harder to see the eyes). This was during a team sports shoot with all the other moms and kids waiting. Mom was later disappointed that there were no shots of her girl looking at the camera and of course just complained to the group and not to me. Fortunately, I heard how "unhappy" she was and adjusted her kid's eyes in photoshop and sent her a print "on me".
Sorry...I'm rambling. You never know what you will run into. Still...that's what I like about it. While all the above was happening, I was totally amused (on the inside). It really was hilarious! Like trying to shoot Bugs Bunny!
Give them what they want...they will remember you and will come to trust you. I have clients now that say, "pick the best one, I trust you".
