Adox CMS 20 II black-and-white photographic film is a low-sensitivity orthopanchromatic film, with an ISO rating of 20/14°. It is characterized by amazing sharpness and fine grain. The sharpness of the image on this film is provided by the “AHU" technology (a special layer with an anti-halo effect between the emulsion and the substrate). The emulsion is applied to an absolutely transparent substrate and can manifest itself by a reversible process, which makes an excellent black-and-white slide out of this film.
