Kodak Verichrome Pan

Kodak Verichrome Pan is a highly regarded black-and-white photographic film that was introduced by Eastman Kodak in 1956. It is known for its fine grain, high sharpness, and wide exposure latitude, making it incredibly versatile. It was primarily sold as a consumer roll film format, most notably in 127, 120, and 620 sizes.

The film was specifically engineered with a thicker, durable Estar (polyester) base instead of standard acetate. This gave Verichrome Pan negatives exceptional archival stability, allowing them to remain clear, flat, and resistant to physical decay for decades. Because of this, it was heavily favored by family archivists, museums, and government agencies needing long-term document storage.

Despite its massive popularity, Kodak discontinued Verichrome Pan in 1980 as consumer demand shifted heavily toward color photography. Kodak eventually replaced its consumer black-and-white market presence with T-Max and Tri-X films. Today, surviving unexposed rolls are considered expired and are mostly used by vintage photography hobbyists.

Yes, if you have an undeveloped roll of Verichrome Pan today, it can still be processed using standard black-and-white film developing chemicals. However, because the film is decades past its expiration date, it will likely suffer from severe base fog, reduced contrast, and loss of sensitivity to light. Many film photographers recommend developing expired rolls in a highly diluted compensating developer like Rodinal.
