Some films were never meant for your camera. Kōun 125 is one of them — and that's exactly what makes it worth loading.
🛰️ What it actually is
Kōun 125 is drawn from Agfa's legendary Aviphot line — a professional aerial reconnaissance emulsion built to photograph the ground from altitude. Aerial film has one job the rest of photography rarely asks for: punch through atmospheric haze from thousands of feet up. Agfa's answer was extended red sensitivity, and that single trait is why this stock renders the way it does down here at eye level — cutting haze, deepening skies, and warming skin in a way ordinary black-and-white film engineers away.
We've kept this batch cold since 2012, then hand-roll it into 35mm and re-rate it at EI 125. Frames shot on it have even surfaced in Lomography's galleries. It's sold here under the Kōun name, but the lineage is no secret — this is Aviphot, revived.
🎞️ The look
- Fine-to-moderate grain with a classic, timeless black-and-white rendering.
- Deep, dramatic skies and warmer skin tones, courtesy of that aerial red sensitivity.
- A surveilling calm — sharpness with a long, even tonal range most B&W films flatten.
📸 How to shoot it
- Meter at ISO 125 — it's happy anywhere from 125–160.
- A touch of overexposure gives creamy highlights.
- Beautiful for landscapes, portraits, and street.
- Polyester base, no antihalation layer — load in subdued light to avoid fogging. This is the one handling quirk worth respecting.
🧪 Developing Kōun 125
Standard black-and-white chemistry — D-76 (1:1), Rodinal, and friends. Nothing exotic. For exact times across common developers, we keep a chart:

🛒 Where to get it
Every roll is hand-spooled into a recycled 35mm cartridge, tested for light-tightness, and clearly marked — 24 exposures, ready for your camera. Shoot it, then tag #koun125 so the world can see what an aerial film does at ground level.
