Development was longer for these images than for normal film, 20 min, not 13. No one knew how to do this. The increase in development made the image much darker than the test, I think. Water was 66 degree so we increased time. It is a little mixed up now. Also, there are a lot of black dots on this one.
Exposure was on 12 ISO, from an average reading of the light patch and a dark stump shadow. It was f 11-16 at 1 sec.
