Adox CMS II ISO 20 is an ultra high resolution B&W negative film designed to be used with Adotech IV Developer for pictorial photography. This combination is capable of achieving grain-free enlargements of up to 8 feet diagonally. This equals to about 500 megapixels in a digital camera. This is due to the special monodisperse ultra high resolution emulsion of the film.

The AHU (anti-halation layer) in between emulsion and base material guarantees sharpness while preventing any halation effect. Adox CMS 20 II has an orthopanchromatic sensitization which differentiates perfectly between colors. So there's no need to use a green filter for portrait photography.

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 IV and then develop in a reversal process.

Natalie ★★★★★

Shooting at ISO 20 forces you to slow down and think, but the payoff is real — developed with the matching developer, the grain just disappears into something almost painterly. I've never seen a 35mm frame hold this much fine detail, even in the tricky mid-tones.

Stella B. ★★★★★

I’ve been shooting at ISO 20 with the Adotech IV developer, and the negatives hold detail that feels almost impossible for film—like a 35mm frame that could pass for medium format. The toner response is smooth, and highlights stay clean without the usual blocky grain. Just be prepared for slow shutt

Mia ★★★★★

The grain-free enlargements are real, even on a 5x7 print from a 35mm frame, which feels like cheating physics. Developing with the matching kit is a must, but the detail in a bright sky shot is honestly like nothing I’ve seen from any other roll I’ve tried.
