Rick, I will swing by as well. The key as zhamid pointed out is to use a tripod. A flash will just light a little bit of the house up, but with a tripod you can take a long exposure shot and keep the "dark spooky" look.

Most of the good pictures to take, would be more inside the garage and Gazebo's than outside.. and it's dark, foggy, and slightly cramped inside so maybe hard to get the good angles. I can turn the foggers off. But it's more about how I should frame the picture...close up...or little far back to get the background details...or have some little fog in the picture or none..etc Pictures I took in the past didn't actually come out that well.

If you come by, maybe go through twice...once so you know where things are, and won't be spooked by anything jumping out at you, and then the second time to take pictures. Nothing will physically touch you, But just if you have your camera out the first time and get spooked by something jumping around you don't want to drop the camera or jump back and bump the camera into a wall.

Or you can just ask the person at the front that your just coming in to take pictures so please ask the actors inside not do move around or do anything spooky
