## Description

Kodak Plus-X Aerographic 2402 aerial reconnaissance stock that expired in 2000, cut and hand-spooled onto 120 backing paper by Film Washi, rated ISO 100.

"K" belongs to Film Washi's converted-stock line: film coated in other factories for technical work, then cut and respooled for ordinary cameras. The donor here is Kodak Plus-X Aerographic Film 2402, a panchromatic aerial reconnaissance negative on a 100 µm polyester base — ESTAR is Kodak's trade name for that base — and Film Washi states plainly that the rolls expired in 2000 but are well preserved. The maker rates it at ISO 100, calls the grain fine and the contrast moderate, and gives spectral sensitivity peaking at 700 nm: the extended red response the original stock used to cut through atmospheric haze, which is why Film Washi suggests it for landscape work. It is red-extended, not an infrared film. Because the donor is 5-inch perforated aerial roll film, the original sprocket holes fall inside the picture area and remain visible along one edge of every 120 frame; the perforated side is marked with a sticker on the backing paper. That is the product, not a fault. Handle in total darkness — the datasheet permits no safelight of any colour — and note that these rolls are hand-spooled onto recycled 120 backing paper, so a few very delicate cameras can struggle with them: never force the winding lever, and secure the roll with a rubber band or tape as you unload it. Loading is otherwise normal, no processing leader is needed, and Film Washi publishes development times at ISO 100 for Rodinal, D-76, HC-110, Xtol, Ilfosol 3, Ilfotec LC29 and Tetenal Ultrafin. Film Washi publishes no frame count for this roll; the number of exposures depends on your camera's format.

## Questions

- **Does film need to be refrigerated?** Store unexposed film in a cool, dark place away from heat and humidity. For storage beyond a few months, refrigeration below 10°C is recommended. Let film return to room temperature in its packaging for 2-3 hours before shooting to avoid condensation.
- **What is the difference between C-41, E-6, and black-and-white processing?** C-41 develops color negative film, E-6 develops reversal (slide) film, and black-and-white negative film uses dedicated B&W chemistry. The Neo Analog Lab mail-in processing service handles C-41, E-6, ECN-2, and black-and-white.
- **What is the difference between 135 and 120 film?** 135 is standard 35mm cassette film, usually 24 or 36 exposures. 120 is medium-format roll film: about 16 frames at 6x4.5, 12 at 6x6, or 10 at 6x7. Check which format your camera takes before ordering.
