PanatomicX

PanatomicX was a brand of black-and-white photographic film manufactured by Eastman Kodak. It was a fine-grain, panchromatic film designed for general-purpose photography, particularly when high image quality and the ability to make enlargements were desired. The "X" in its name indicated its panchromatic sensitivity, meaning it could accurately render all colors of the visible spectrum as shades of gray.

Introduced in the early 1930s, PanatomicX was known for its very fine grain structure, which allowed photographers to produce sharp, detailed images even at larger print sizes. This made it a popular choice for portraiture, landscape, and documentary photography where subtle details were important. Its moderate speed, typically around ISO 25-32, contributed to its fine grain and wide tonal range.

Kodak continued to produce PanatomicX for many decades, making it a staple for many photographers. Over time, advancements in film technology led to the development of other fine-grain films, but PanatomicX maintained a loyal following due to its distinctive look and consistent performance. Production of PanatomicX film was eventually discontinued by Kodak in the late 1980s or early 1990s, as the company shifted its focus to color photography and digital imaging.
