hi. i have a question. basically im just getting into wedding photo, and the weddings i have shot in the past i have done proofing through the mail with dvds- i would send one to the customer, and the customer would write back to me and tell me which image numbers to make black and white and which to make sepia. i was wondering, is there such a thing as a gallery software that would let me post photos online and give the viewer the option of choosing black and white or sepia as an option as an indication to me? does such a thing exist?i tried to look a bit, but i havent found anything. i dont need it to sell prints for me. thanks!
