I'll check with our events manager. I can't remember the name of it, but I do know that when they take a picture, you also have the option of requiring your reps to fill out a few fields as well that get entered based on your SFDC fields. The only downfall that we've found is that unless we create a different "survey" for each show, we can't automatically add them to the campaign in SFDC as leads. But, that's a real quick report that we run to keep updated.
