Kodak Eastman Double-X 250 is a black-and-white panchromatic film primarily utilized in cinematography, notable for its ISO rating of 250 in daylight conditions. Introduced by Eastman Kodak, the film exhibits a broad exposure latitude, moderate grain structure and balanced tonal gradation, facilitating consistent exposure across varied lighting situations.

I buy my Double-X respooled from Otterfilm. So far I am quite pleased with the results, particularly the pictures in bright sunlight that are overexposed.
