Just wondering how portrait photographers go about selling multiple prints of the same image? We all know the cost of a print is pennies but when you take into account the amount of money spent on equipment as well as time and expertise in taking that image, and for pro's, a living, then that cost deservedly becomes many pounds. BUT what's stopping a client from buying just one image and scanning it to give to all family/friends one. I haven't done much paid work but what I have I've just sold them a cd-rom. If I went down the route of selling prints, how would I make money from selling more than one print of the same image?
