Hi folks, time I joined this side of the forum.. The Glory Hole is a large pinhole camera my friend made that has shot mostly reversal paper in 20 x 24 and 24 x 40 inch sheets. The "Lens" resolves about 25-40 lines per millimeter in the center of the 48 inch projection area and holds up well on a single 20 x 24 sheet....it looks darn sharp in print. As I am building a large darkroom, I am going to be using Arista Ortho-Litho film in the pin holes to make contact sheets onto paper with. I am SO excited about this, we already have a show planned. Anyway, I just thought I would share this and come join the fun!
