The Photoarts Guild that I belong to held a demonstration of our Camera Obscura today at a local art sale. I so enjoyed learning how this beast works but mostly showing people what it was and that they could "walk" into a camera. As i was explaining how a pencil drawing could be made using this camera, a fellow artist pulled out his little sketchbook and started to make his sketch. (upper right image)
We had a camera obscura in the Portland Children's Museum. I don't know if they took it with them when they left or if it remained in the building. Good collage
