With our first photo booth being a success, we have run into a small issue, and I finally am looking for help - When the flash on the Canon T3 Rebel isn't used, the pictures look pretty dark - We run a pipe and drape adjustable set up, which is usually 4-5 foot wide by 5-7 feet deep. When I have the flash on the camera on, the pictures look GREAT, but there's ONE problem - With the possibility of someone moving in the booth or whatever, the camera takes a refocus and delay flash. Any suggestions? Could I hook up just any kind of strobe light (this is where I'm completely ignorant), if so what kind? I don't think the Canon T3 Rebel accepts a Sync cord, which would make me get a hot shoe? Any suggestions out there? Those of you with a Canon T3, do you have settings set differently to not have delayed flash? ANY help is greatly appreciated!
