Adox CMS II ISO 20 is the one of the sharpest, most fine grain films available. If used in pictorial photography the film achieves ISO 12 to 20 when used with Adotech II developer. The film achieves grain free enlargements of up to about 8 feet diagonally. This equals about 500 megapixels in a digital camera. This is due to the special monodisperse ultra high resolution emulsion of the film. ISO 20, Ultra-High Resolution Film, AHU anti halation layer guarantees sharpness yet preventing any halation effect. The AHU anti halation layer in between emulsion and base material guarantees sharpness yet preventing any halation effect.
Adox CMS 20 has an orthopanchromatic sensitization which differentiates perfectly between colors. No green filter is necessary in portrait photography.
When used with Adotech II developer, this film produces perfect halftones and creates images no one would possibly believe to have been made with a medium format film. If developed in Adotech II you can expose CMS 20 to ISO 20 and get images with perfect halftones. In low contrast situations and with prolonged developing times the achievable speed increases to up to ISO 32. The film's base is totally transparent making it possible to reverse it and use it as an ultra-high resolution slide film with extreme projecting possibilities. In order to achieve this, develop the film in Adotech II and then develop in a reversal process.
The manufacturer does not supply this film with expiration dates as the film is very slow and stable for many years.
Please note: Adox CMS II 20 should be developed with Adotech CMS II developer only, other developers are not recommended.
