Frequently I have been a judge at various art festivals in my area (atlanta) 4 shots are required, 3 of the work and one of the booth. I can't even begin to express how often the booth shot is awful. The guide line for these events are very clear about what shouldn't be in that booth photo. It is shocking that folks who "think" they are artist can't comprehend what a nice image of their working booth means.
You may try getting in touch with the local artists and talk them into hiring you to not only take a photo of their booth, but also be sure it is well lite, no people, no names, no trash. All those items knock down the score for the judging process.
