The Daylab 4x5 Pinhole Camera is a modern day 'camera obscura', a popular way of capturing images in the 19th century. It has a modern Graflok back, so that it can use current sheet film holders, instant single-sheet film holders, or instant peel-apart pack film holders (such as the currently-available Fujifilm PA-45). Instead of just a single pinhole aperture, it has 3 different apertures.
The 'C' aperture is appropriate for instant color films with sharp imagery, the 'BW' aperture is best for black and white images and non-instant color films, and the 'Soft Focus' aperture produced the most diffuse image results.
The 4x5 Pinhole weighs only 11 ounces and has a standard 1/4"-20 tripod threading. Assembly is required.
