Today was the great photography workshop hosted by Charles Steuck!
First he talked, of course, about photography (what is a photo? what is a camera? a camera obscura? etc.).
After this, Charles presented us a kind of a selfmade Camera Lucida or such a finder, because it hasn't a mirror or prism. Many landscape painters and photographers used and use a camera lucida or a finder for a better view.
Everybody got one and we should go out and use it with a normal camera or just with our eyes.
