They're all good, but that second one is hella cool. :thumbsup: Love the angular look set off by the circle of the pinhole. Nice!!!
On another thread, you captured an image with the paint can, too, didn't you? *WILD APPLAUSE* for playing with these alternative imaging techniques - and having success! More, please.
I love the shots taken with the Diana! The shot of the camera is a little grim. Personally I would shoot the camera with the lens being the center. Be sure to check out terri's thread on the Holga.
