Both are FujiColor 200 at box speed, on 35mm rolls in the 120 tank. These turned out to be 24-exposure rolls (well, I did explicitly ask for the cheapest color film available for this experiment). Trying to see whether some of the defects of the last C-41 cross-processing experiment can be remedied: The operating theory here is that the last rolls of C-41 (rolls 1093 and 1094) came out very grainy, and with low contrast. The Facebook Caffenol group claim that this is normal for C-41 in B/W chemistry; I’m wondering if that can be held back by lower-temperature development with more iodized salt. We’ll see.

Took remainder of Caffenol C-L from batches 1101 and 1106; put the beaker holding it in water at 62 degrees at the bottom of the cooler to bring the developer temperature down. Added 7g of iodized salt. Allowed to cool to 62 degrees. The Time/Temp Converter suggests 97 minutes and 42 seconds at 62 degrees; I’m just going to go ahead and round up to 100 minutes here.

Overall composition for this 500mL of Caffenol C-L: 8g washing soda, 5g ascorbic acid powder, 10g iodized table salt, 20g Folgers instant coffee. Pre-wet film ~10 minutes at 62 degrees. Poured out water , then poured in developer; agitated 15x over 30 seconds, then 10x over 15 seconds every twenty-two minutes thereafter, to a total developing time of 100 minutes. Alternated which end was up at every group of agitations. Kept the cannister in the same water bath in the cooler during the cycle, trying to maintain 62 degree temperature. Dropped three pieces of oval-slice freezer ice in to the cooler after agitating 22 minutes in, then discovered that temperature had fallen to 59 degrees at 44 minutes. Added warm water to restore temperature of water bath to 62 degrees, then just kept cooler closed with no further cooling for the rest of the development cycle, on the theory that the slight rise in temperature as the cycle progresses will hopefully compensate for the lower temperature earlier in the cycle.

After 100 minutes, disposed of developer, rinsed in 68 degree water, filling and emptying the tank until the water rinsed completely clear, then four more times. Fixed in Ilford Rapid Fixer 1+4 for 7 minutes, turning 10x over 15 seconds at the top of every minute. Recaptured fixer and rinsed for ten minutes, then hung to dry.
