I've attached two images. The one of the room is Caffenol-C @ 20min. The monkey is Caffenol @ 30min.
The Caffenol-C negatives came out looking dark. I couldnt put my up to them and see through them like tinted glass. However, when put up to extreme light I could see tons of highlights. They scanned like crap though. There wasn't enough range and I think the scanner had to blast too much light.
The Caffenol negatives came out with being able to clearly see through them. The highlights werent black enough so I know I must simply adjust my development time.
I'm wondering why the Caffenol-C behaves so much differently. The negs dont seem to be underdevloped, but they don't seem to overdeveloped. Yet I can't see the images at all with my naked eye like I can with regular negs.
Caffenol Negs - see images with eye, see through, tinted
Caffenol C Negs - only see images with backlight, not tinted, not much range
