Was thinking this might be a great place to take senior photos - is there anything preventing us from bringing a photographer along with us to take more professional photos?

Hi! Thanks for asking, as long as a ticket is purchased for all guests entering the venue (photographers included). Please note that the photographer cannot bring tripods, external flashes and lights and excessive props. Also we do not allow outfit changes as it disrupts the flow of the exhibit, as we have many guests coming through at the same time and using the spaces congruently.

I would confirm with your photographer that they aren't bringing tripods/off-camera lighting equipment, etc. Just the camera wouldn't be a problem.

I'd call them to ask. I wouldn't think so since you can already take your own photos as much as you want. But again, I'd call to ask (they may can also tell you a good time to go when it's less crowded)
