Has anyone DIY'ed a photobooth? I'm making the backdrop and props myself, but I don't have an iPad/stand as others have suggested for the actual picture taking. (I don't want to buy a Polaroid/Instax or anything like that.) I figured just bring a universal tripod and everyone can use their own phones with a timer, but I'm worried about the lighting. Has anyone had any experience using a selfie ring light for a photobooth? Which one did you buy?
