Folks they don’t make grain any smaller than this! Up for sale is a very rare box of Kodak Technical Pan, an ISO 25 B&W panchromatic film that makes up for slow speed with insane resolving power. This box of Tech Pan contains twenty five 8×10” sheets of B&W negative film. Recommended processing with Kodak Technidol or other like B&W developers. Frozen since coming into my possession back in 2014.
