I did a PB session for a friend back in April and I sent a disk to her with about 20 or so images on it. Edited. Watermarked. and offered her a free 5x7 print. She now wants a disk of the untouched images and not the disk. She is willing to pay me for it but I dont want to give this to her with fear that she post them and what not or edit them herselves and call it her work. Not sure how to handle this one, suggestions?
