Fun with caffenol-c and HP5

[like2fiddle]

I did a little experiment over the weekend to determine how to rate HP5 when using caffenol-c as a developer.

Sorry, but I have to do this in four posts even though the images are very low resolution scans on a 4490. No manipulation of the images at all except unsharp mask when scanned. They're not great quality, but I'm only shooting for the best film speed to use with HP5 and caffenol-c.

The first two pairs of scans were all taken with the aperture remaining fixed @ f 1.4 and exposure adjusted via the shutter speed.

The second two pairs were exposed by manipulating the aperture and keeping the shutter speed at 15.

All taken with M2 and Canon 50/1.4.

Have you tried printing with the cafenol? I tried it once and it came out okay. I have to do some more testing myself.

No, I haven't tried printing yet, but I intend to. I've seen posts here and there about printing with caffenol, but not caffenol-c. Am I just missing them, or is there a really good reason not to use the caffenol-c to print?

In post # 3 are you sure you didn't mix up the ISO on the two shots? Looks a bit strange.

Overall, I'd say ISO 200 is about right, but 400 is not bad at all.
