Basicly all I have is a Canon A510, and am interested in shooting this abandoned building. Problem is, I don't know how much light will be let in by the foggy windows. I'm not sure if I can use exposure times to let enough light in. Since all I have is the basic flash on my camera, that I really DONT want to use. I was wondering what other types of lighting I could use? One of my friends offered to bring a spot light...which may end up being too bright, but if I used a fast enough shutter speed f/stop maybe I could retain the 'creepyness' of the area....it's quite a frightening factory, from what I hear from others. Another idea I had was take my 100watt halogen light...problem is I want to retain alot of natural lighting, but if I can't, and it's all too dark it's going to be a wasted trip. I want to come prepared whether or not I can use the lighting in the building. Obviously I'll be going in the daylight, but I'm not sure how much light will be allowed in by the place. Someone also said that the place was retro fitted with flourecent lighting, so it might be that I could use those.
