Product Description

The CPB Darkroom is proud to introduce Infinity – Variable ISO Film, a brand-new roll innovated by Anshul Bandhiwal. This is India’s first indigenous black-and-white film that allows photographers to change ISO mid-roll—from ISO 100 all the way up to 3200—giving unmatched flexibility in a single cartridge.

Whether you’re a beginner exploring film or a seasoned professional, Infinity is designed to adapt to your shooting style. With its wide ISO latitude, you can confidently shoot in bright daylight, dim interiors, or neon-lit nights without switching films.

Infinity features a classic tonal curve, rich contrast and expressive grain that changes character beautifully with exposure. At lower speeds (ISO 100–400), it offers smooth tones and clean detail, perfect for portraits and landscapes. When pushed to ISO 800–3200, it transforms with bold contrast and textured grain, ideal for street, documentary, or experimental photography.

Developing & Scanning

• When you finish shooting, you can book your roll in for processing through our Processing Page at no additional cost.  Link

• If you would like scans and/or your negatives shipped back, you can choose from our scanning and return services on the processing page.

What is Respool?

Respooling is the act of taking bulk film (sold in hundreds of feet) and spooling them into 35mm cartridges by hand. At CPB, this is done in a light-controlled environment using specialized equipment, producing results identical to factory-packaged films—while keeping film accessible and innovative.
