Homemade 8×10 Camera Created with Foam Core and Rubber Bands
This foam core 8x10 camera was created by Daire Quinlan, the same guy that attached a 90 year old lens to his camera with homemade bellows.
The lens is an Industar 37 Russian large format 300mm designed for their FKD cameras. The shutter is a Sinar, takes standard 8x10 film holders.
Quinlan exposes onto photo paper instead of film, and focuses the camera by sliding the rear box forward and backward.
