Re: [pinhole-discussion] Powder vs. Liquid

I prefer liquids because you can mix single shots. Right now I use Rodinal a lot for Delta 100, HP5, and FP4 (all 4x5, 8x10, 7x10 so I don't mind the grain). I had been using HC-110 for some time previously. To me, the shortcoming of dry chems is that you have to mix entire batches. I don't have a

Mike, what film are you using? I'm using Kodak CGP/2588 myself. The recommendation is for a #1A. However, I also am getting away with using the Delta 1 Bright Lab Jr. It's a red bulb you can pick up in the darkroom dept of a camera store. I work at least four feet from it, and don't seem to get

Becky, I use a #29 red all the time with Delta 100. It's more convenient to apply it to the front, but I have attached mine to the back, and it's fine. Probably better, actually, since your depth of field is great enough that a filter that's 1/2000th of an inch ahead of the pinhole is going to be

Andrew, I'm with Andy on this one. Just give it a try. You bet you'll get falloff. When I shoot 4x5 using 50mm of focal length, the fall-off is a good 2-3 stops from center to corner. Not only that, but with a focal length that barely covers the film (or even doesn't), you can get very interesting

Re: [pinhole-discussion] resolution vs diffraction vs format question

2003-02-22 Thread Michael Healy
Indirectly, there is some truth to the argument that larger formats have better resolution -- but this is only the case because we usually end up enlarging the larger format less. So a 35mm image enlarged to 8x10 will suffer degraded resolution when compared w/ an 8x10 contact printed from 8x10

Ed, you might try the MACO 820IR film. It's sensitive to higher nanometers than the other spiked red films. It also comes in 120 and 4x5. I recently shot some in my Fuji 6x9, using an 87 IR filter. Long exposures, but very nice. And the film is pretty fine-grained in Rodinal. I haven't yet used
