Another caffenol stand development pair. I’m on a roll with this stuff today! Both are Ilford Delta 3200 at EI 3200, and I’ve recently seen some good stuff with stand development on the Facebook group.

Caffenol C-L: mixed only 500mL: 8g washing soda, 5g ascorbic acid powder, 3g iodized table salt, 20g Folgers instant coffee, in that order, dissolving each completely before adding the next. Prewet in tap water at ~68 degrees for ~20 minutes, then poured out water and poured in developer. Agitated 10x over first 15 seconds, then let sit. Swirled gently six times with 30 minutes remaining, then let sit. Rinse as with previous batch, then fix in Ilford Rapid Fixer 1+4 (replenished with 90mL new fixer +360mL water, per instructions), 7 minutes, agitate 10x at beginning, then 5x over 10 seconds at top of each minute. Rinse ten minutes in slow cold (~60 degrees) water.

1065 is very grainy and has comparatively low dynamic range – there are those online saying Ilford Delta 3200 is actually an ISO 1000 film, so it may simply have been underexposed … though I think that I almost certainly just let the camera read the DX coding to set the film speed. But roll 1071 seems to have come out decently, though it is rather grainy in places, so perhaps 1065 was just exposed badly.

Reinhold recommends doubling iodized salt for high-speed films. He says here that 15-20g/L iodized salt for high-speed films is reasonable.
