Kodak BW400CN and Fuji Acros Compared in Caffenol C

Here is an interesting side by side… shot within a few minutes of each other. The BW400CN is an EI of 200 (this film in my Caffenol C process has a very usable EI range from 50-800). The Fuji Acros is an EI of 100 (box speed… depending on processing time the Acros has a usable EI from 50-800). Both can go further in either direction but this range is the real sweet spot. The crops represent a 4″ x 4″ from a 20″ x 20″ image size… yes the BW400CN has more grain but it is much sharper and I am not sure the grain would even print at the 20″ x 20″ size. Both films have fantastic reciprocity characteristics with no adjustment required until 120 sec.

When you hover over the image it will give the description of the thumbnail.

Fuji Acros Caffenol C EI Range Test

This is really amazing… with ┬ámy final tweak the Caffenol C process is giving me Fuji Acros with a usable EI from 25-800… I suspect that 1200 would also be fine… this is all with the same processing time / technique. The scan was a s straight scan with no sharpening and each image was just set for proper contrast in PS… wow!

Wait till you see the TMAX 100… I’ll post it tomorrow, it is equally amazing.
