While thinking up ways to entertain my children on a cold winter afternoon, I came up with the idea of turning a spare room into a camera obscura. I thought this room in particular had some very interesting qualities, that might make for a good example of a camera obscura. There is one wall that faced Puget Sound, and that wall had a large glass door in it. The back wall onto wich the exposure shoud be projected, had nothing hanging on it. It seemed like the perfect making for a camera.
