I am starting to go to car events and take awesome rolling shots of cars. It doesnt go great yet, but I can see it take off if I advertise better. Advertise it on car forums and hand out business cards to car owners of the cars I took. I do not sell prints, I just sell them the high res. files. I would like to put a release form that mention that they have the right to use it for personal use and not for commercial use. Can someone lead me to the right direction? Also, lets just theoratically say that a Hot Rod magazine does want to use my image. How does it work typically? What do people typically charge? What if the person wants to use the photo for his business website? I am just wondering all the possibilities. Thank you!
