I shot a few pinhole rolls at Burning Man using the Zero Image 4×5 and a 120 Graflex “23” adapter on the back.
I really like the wide angle that the 4×5 gives, because the pinhole is so close to the film. But that produces some pretty extreme vignetting. Even when shooting with a 120 back. Visualize a much less cropped image, with almost black edges.
I shot all these in daytime, with an exposure time of about 3 or 4 seconds. Pinhole Assist recommended just 1 or 2 seconds, but overexposing doesn’t hurt when shooting C41. The film was Ektar 100.
Well I didn’t shoot as much as I wanted – only 2 rolls. Maybe I brought too many cameras to shoot any very much. Still, so glad I brought this one.
