Taken with a homebrew modified Agfa Isola 2. Will try to post pictures of the setup when I have time.
The Isola is a collapsible tube camera. The pinhole was placed where the front meniscus lens used to be, so focal length of the picture above was ~85mm. For the next two pictures, the tube was collapsed, which caused the masking (vignette) effect. Focal length is ~45mm.
