I'm considering shooting some landscapes on Adox CMS 20. Does anyone have any advice (please include examples shots!) on how to get the best tonality from the film? The promise of high resolution is very tempting but the film appears to be difficult to work with. I've had a look at filmdev.org but there aren't too many examples... From what I've read and seen so far, negatives tend to exhibit excessive contrast and little highlight or shadow detail when shot at ISO 20 but the situation improves when the film is rated around ISO 12 (this is also stated by Adox). Many people, however, believe that the correct ISO is actually ISO 6. Is this true? I can't find any examples of scenes shot at ISO 6. How should development be adjusted? I don't know much about darkroom theory: how will shooting at ISO 6 improve tonality? If I gain shadow detail, will I burn out the highlights? Some people also advocate exposing for the shadows... It also seems that poor results are to be expected if the film is developed in anything other than Adotech and there seem to be fairly substantial differences between the Adotech I and Adotech II developers. Is this true? Adox have, no doubt, spent a very long time perfecting the film and developer but it's not impossible that someone may have found something better.
