The ADOX CMS 20 II 135 is one of the most remarkable black & white films available today, delivering ultra-fine grain, exceptional resolution, and unparalleled tonal range.

Whether you are a fine art photographer, an archivist, or a dedicated film enthusiast, ADOX CMS 20 II 135 offers you an extraordinary level of detail and clarity.

Why Choose ADOX CMS 20 II 135 for Your Photography?

Photographers looking for maximum image fidelity often face a choice between larger film formats or specialized 35mm emulsions. ADOX CMS 20 II 135 bridges that gap by providing resolution and tonality comparable to medium format, all while maintaining the portability and cost-effectiveness of 35mm film.

In fine art and archival work, resolution matters. The ADOX CMS 20 II 135 captures even the tiniest textures, making it perfect for landscapes, architecture, and scientific documentation. Its unique emulsion structure ensures that your negatives hold detail even under high magnification.

Ideal Shooting Scenarios

• Fine Art Landscape Photography: Capture every leaf, blade of grass, and rock texture with breathtaking sharpness.

• Architectural Photography: Straight lines remain distortion-free with incredible edge definition.

• Scientific & Technical Photography: Suitable for microscopy, document reproduction, and forensic imaging.

• Portraiture: Smooth skin tones with striking depth and clarity.

Developing ADOX CMS 20 II 135

To unlock the full potential of ADOX CMS 20 II 135, it should be paired with an appropriate developer. ADOX recommends using their dedicated CMS developer for optimal tonal reproduction and minimal contrast issues. You can also explore alternative fine-grain developers, such as the ADOX NEUTOL Liquid NE 1000 ml, for high-quality results.

For those seeking classic black & white processing techniques, check our range of B&W chemistry, including the FOMA Fix P U1 and the MT1 Selenium Toner, which can enhance the archival quality and tonal depth of your negatives.

Printing Your Masterpieces

The detail captured on ADOX CMS 20 II 135 is best appreciated in prints. Pair your negatives with premium darkroom papers such as the FOTOIMPEX Easy Print RC 312 – 9.5×12 inch Pearl Finish for gallery-quality output. This combination ensures that every subtle gradation and textural nuance is visible.

For beginners and professionals alike, exploring the art of enlarging can be highly rewarding. Learn more about the history and process of film photography on Wikipedia and how traditional printing techniques can bring your black & white work to life.

Why ADOX CMS 20 II 135 Stands Out

While many modern films focus on versatility and higher ISO speeds, ADOX CMS 20 II 135 is a specialist film that prioritizes maximum image quality above all else. It appeals to purists who want every pixel of resolution from their negatives. In an era dominated by digital, this film reminds us of the unmatched beauty and discipline of shooting on analog.

Its clear polyester base also means it has exceptional archival properties, making it a great choice for preserving historically important subjects or producing long-lasting art prints.
