So, I am a hobbyist photographer. There are some days I am out and about and see someone or some child that I would just love to do a shoot of. How do you go about asking them? Have you done this? Do I just offer my card? would you pay them with money or pay them with pictures or just assume they wold do it for free? Is it creepy? Please tell me what you have done and if it worked(s). If I am not intending to sell anything and am just doing it for my own portfolio or whatever do I have to have a model release signed? Thanks.
