Do you put any limitations on the use of the food photos?
Some photographers do, but I do not. It’s called “usage”. Photography is considered an art, like music, and falls under the copyright laws. A photographer is allowed to “License” their photography for periods of time. What this means to you is that as a buyer of food photography, you need to make sure that you and the photographer you are working with, have the same understanding when it comes to usage.
I give my clients “unlimited” usage, which means that they can use the images for as long as they want…
