I do a lot of freelance TFCD shoots as I'm building my portfolio. Most of my models are also building their portfolios too. Generally, after a shoot, I go through the images and then post them to a secure location online for the model to download. Who knows what they'll do with these images. Should I be watermarking my images? Should I require all models (unpaid) to sign a release? Secondly, I've recently done some work for bands who will use these images for promotion. One band in particular, a friend, will use the images for promotions and press. At this stage in game, credit is more important than money. Should I simply ask for credit? Assume they'll give it to me? Or watermark the images? Thanks for your help.
