All images developed in Caffenol-C-M as described in former post. On my desktop screen, the 10x10mm crops represent whole images of 1.30x1.30 meters print size for 120 film and still 50x80 cm for 35mm film! Caffenol-C-M enhances film speed without changing anything. Compare the EI 100 and EI400 images, both from the same roll, there is almost no loss. Just a tiny little bit more grain.
The last image is a 10x10 mm crop from the TMax100 exposed at EI 200 ASA. Almost no grain, extraordinary rendering from highlights to shadows, usable exposure range from 25 to 800 ASA. The subject had a contrast range of 9 stops. All in all this combo can handle a contrast range of 13 - 14 stops! And you need an extremely good lens to scratch the resolution limits. That's what I call "state -of-the-art".
Images 1-3 made by a 65 years old Voigtländer Bessa 66 with uncoated 3.5/75 Skopar, image 4 made by Pentacon Six with 2.8/80 Carl-Zeiss-Jena Biometar and z-ring.
Stay tuned. More to come ...... Reinhold
