Show More
The Adox CMS 20 II Professional Black and White Negative Film is an extremely high resolution, fine-grained film featuring a slow nominal sensitivity of ISO 20/14° when developed with the recommended Adotech II or Adotech III developers. Slower speeds can be used to reduce overall contrast or when utilizing other developers. A unique monodisperse emulsion layer provides high sharpness and resolution with virtually no perceivable grain, and an anti-halation layer has also been incorporated between the emulsion and film base to maintain consistent sharpness void of halation effects. The film's base is completely transparent, making it well-suited for scanning and copy work, as well as reversal processing techniques (using Adotech II/III as a first developer) for projection. Its orthopanchromatic sensitivity is responsive to all light and requires no filtration for pictorial applications.

question

compared to ektar 100 B&W, how good is the grain structure and post processing results for this film?
Asked by: Jesse
Ektar files are more forgiving in post, and of course there's the tones that used to be colors that can be individually manipulated in B&W; Ektar B&W conversions can look very good, whereas Adox CMS 20 when the planets are aligned can appear stunning. I don't use colored filters with CMS 20, it doesn't need them

question

Can i develop this film in Ilfosol 3 ?
Asked by: Trey B.
I haven't used ilfosol 3 for this, but the massive dev chart shows 1+14 for 6 minutes. I would try this first and tweak from there.I personally stand develop in 1+200 Rodinal for 1 hour after shooting at iso 12.

question

The spec says the recommended developer is Adotech II, which is discontinued. What are the recommended alternatives?
Asked by: Adam S.
Adox CMS 20-135 EI 12: Develop in Photographers Formulary TFX-2, 1+1+10 dilution 14 minutes. Continuous agitation for the first 30 seconds or more, 20 second agitations per 3 minutes thereafter will reduce contrast that can otherwise be severe. Negatives will appear a bit thin; underdevelopment works well with this film and developer taking an extra bite out of contrast. Been waiting to try TFX-2 developer with the 120 format, but it hasn't been available for quite some.

question

How am I going to develop this film? My college have a lab for B&W developing but since Adox films need special developer, what is the dilution ratio and time for developing?
Asked by: Benjamin K.
Hey Benjamin,According to the Adox data sheet for CMS 20 and Adotech III developer, the dilution for development is 1+9. Agitate for the first 30 seconds and then once per minute. No need to pre-soak the film, as it will increase contrast, you must use an acidic stop bath, and you only need to fix this film for 30-60 seconds. Overfixing will lead to burnt out highlights. You can also shorten the wash time to 5 minutes. See the full data sheet here:http://www.adox.de/Technical_Informations/CMS20_ADOTECHIII_instructions.pdf

question

Has anyone shot both Adox CMS and Rollei RPX (25 ISOs)? Comparisons?
Asked by: Karen
Yes. Both great. Finer grain on the Adox I'd say. Rollei may have had a little more contrast, but I was in a totally different environment. I really loved the results I got from adox.
