The Lumenbox was a 9 hour interior, looking out the window shot. I think it was a bit too long of an exposure for such a bright day. When I see black on the photo paper (white of course when I reverse it), that indicates to me that I could have gotten better colors with a shorter exposure time. Live and learn.
The Cámara Galletita Lumen print is actually with the pseudo-slit “lens” I made earlier. I’ve had a devil of a time getting decent exposures (well, decent for this sort of thing) with it.
Both exposures were on the usual Arista Ultra Edu grade 3 b&w photo paper.
