Is there a way to watermark a picture so it doesnt show up on the orginal, but if the person were to take it to get more prints or scan it, then the watermark would show? I just started my own photography business and my clients asked if they could just order prints first without the watermark that i had on the proofs, so they could show ppl first before ordering more. I just dont want to get ripped off which i know they could not do that but i was hoping there was some way that i could protect my pictures without having a watermark on the orginal???
