i am taking pictures tomarrow and I will be using my sb600 flash for fill flash. I won't be using any type of reflector boards. Any tips? I don't want to blind the person and I don't want the pics to be too over exposed. I want the pictures to come out exposed good and crisp. I will be taking the pictures outside in the late afternoon. I have been learning this flash forever now and love it, but I just want some good tips from all you external flash users Thanks!
