Interesting. I have been trying out CMS20 in my EOS 50 now in the winter, and I find that if I trust the evaluative metering in the camera, it consistently underexposes the film. (Most likely the snow is fooling it) If I meter the ambient light, or use the large spot meter of the EOS 50 and meter the shadows, it turns out all right. I expose at EI 25, and have used a variety of developers, all giving acceptable results, at least for scanning:

3. A Stoeckler type two-bath developer with 5 grams metol and 25 grams of sulfite in the first bath. Anchell & Troop says two-bath developers does not work well with document films, but Agfa recommended it, I seem to remember, and it seems to give slightly better shadow detail than the first two developers. The A bath of this developer will develop film by itself, so time in the first bath does influence the results. I used 3-4 minutes.
Just a quick followup. I have now also tried a very dilute Beutler developer with CMS20. 0.2g metol, 1g sulfite, and 1 g sodium carbonate. I developed for half an hour with agitation every three minutes or so. Contrast is a bit low, which indicates that I could have used a less dilute developer, but the shadows are OK. The attached image was exposed at 25 ISO at 1/125 and f5.6.
I have forgoten to do a followup here ...
In fact I finally tried to use the film at 10 iso and then I have
used nearly the same procedure for develloping (Rodinal 1+50,
21░C, 11 min).
The results are shurly improvable but it is a lot better than my
I attache to this message one of my scans and a 100% crop (3200 dpi)
I have used adox CMS 20 with rodinal 1+100 -> same (not very good) results as you. With Adotech developer - excellent results.
If you like slow films - try efke 25 and kodak TP in rodinal - I got very good results in rodinal 1+100 with efke 25 and TP (dev times from massive dev chart).
for 1 L Stock ?

Hello olehjalmar, could you please tell me the composition of bath B of the Stoeckler 2-bath developer?
Use the Zone System or at least expose as if using the Zone system. So if you want texture in your shadows, meter them and place them on Zone III. Make the exposure. Develop using a compensating developer, my preference with CMS 20 is OBSIDIAN AQUA but I'm sure 510-PYRO would also work, with a stand or (my preference) a semi-stand regime like this: http://freepdfhosting.com/a1e73b320a.pdf
