*shivers and whimpers pathetically* Why oh why did I hafta read this before going to bed? *Cries quietly* I hate this stuff, and yet I can never just look away... ;_;
I agree that those pics are way creepy. And even though I know how they're made, I still can't help getting creeped out. Anyway, I'm willing to bet that none of those photos have been photoshopped. Why? Well, because they didn't need to be. Older cameras required a lot of time to develop a single picture. And if you wanted to superimpose a ghostly image onto the film, all you had to do was open the shutter and let it alone for a little while - just long enough to get the base for the background onto the film - and then cover the lens with something (a hand or a piece of paper will do). Then, just have someone stand in the middle of the area you're taking a picture of. Lighter clothing will make the effect much more dramatic, because it'll show up more. Anyway, uncover the lens again, and then, after a few seconds (maybe more, depending on the make of the camera and the type of film) cover the lens again. Have the person leave the area, and then uncover the lens again. Allow the camera to finish collecting the image, and then close the shutter. When you develop the film, you will have a ghostly image of whomever you had standing there on your picture. You can do that with an old camera really easy, and it can be done just as easily with new cameras that allow for timed exposures. I do photography for a hobby, so I've learned a lot about those neat little tricks. In fact, in one of my photography classes in college, I did ghost pictures for my final project. :) Since a lot of the better images people captured ended up on the walls of the hall outside the classroom, my images got a lot of attention from the other students, lol. Some of the bolder ones wanted to know where they could find the "haunted house" I'd taken my pictures in. :P
But despite all my knowledge of this, that doesn't mean I can completely count ghosts out. I think they might exist, but I certainly don't want to meet any. And I really don't want to think about becoming one! *Shivers again*
