Some photographers with more enlightened business models will do a shoot and then give you an agreed-upon subset of the images (2 or 3) with copyright transfer.

Some photographers with more enlightened business models will do a shoot and then give you an agreed-upon subset of the images (2 or 3) with copyright transfer. If you want the others at some point, you can pay an additional fee. This way, the photographer still has the potential for later additional profit, and you have the copyright for the photos you like best. Everyone wins.
