P.F. Ybor 25 is vintage 35mm Ilford PAN F Film stock; hand-rolled by Ybor Analog.

Process in B&W Chemistry. The film is rated for 50 ISO, but due to its age, I recommend 25 or lower.

Ilford PAN F is a fine-grained, high-contrast, low-speed film. 

Sample shots were taken on a Canon A-1 with a 50mm 1.8 lens at 25 ISO. Seymour is in full shadow in the first, and straight up hard early afternoon Florida sun in the second. Developed in Kodak HC-110 Dilution E for 8 minutes, with 30 seconds of agitation at the start and gentle inversions at the X:30 mark each minute.

Lazy flat scanned with a Google Pixel 9a and inverted via a quick tone flip in Lightroom; no adjustments made.
