From what I learned last year and this year:
Video cameras are a no-no in the indoor haunts and shows. I don't believe Psycho Path or the scarezones have a restriction on video cameras, but I'm not positive.
Still cameras are okay, with the flash turned off. Although Cedar Point allows the use of flash in the outdoor scarezones, so you might be able to use flash at Worksite, Cornstalkers and Fear Street.
I know that flashes are being used quite often with the scareactors posing for photos on IStreet and the new zone in Paramount Story.
Just to be safe, I would check with the greeter at the attraction. I've only asked so far at Psycho Path, and was told that if the flash is off, cameras are fine there.
