4×5 Pinhole Camera
This is a dual 3″ and 6″ focal length camera with pinholes mounted front and back, separated by the 4×5 film holder slot, located in front of the handle.
8×10 Pinhole Camera
Based roughly on large format, view-camera design, this camera has three focal length attachments (two of which are visible). The 12″ attachment is seen mounted on the rear for a standard focal length, and a 6″ attachment on the front for a mid-range wide angle (only one of which would actually be used during the picture-taking process.) A 3″ attachment (not seen) is used for extreme wide angle shots. The slot located at the middle is for the ground glass viewing screen and 8″ x 10″ film holders.
Hexagonal, Six Pinhole Camera
This camera has six pinholes that can be used either sequentially or simultaneously. As a result, it can produce up to a 360 degree panorama image. Film is mounted on various interchangeable cylinders or flat-planed boxes in the interior, depending on the intended composition.
