f/64 is a camera with one promise: what the sensor saw is what you keep. PURE RAW Every shot saves a true Bayer RAW (DNG) next to the HEIC. No AI, no computational tricks, no Deep Fusion, no Smart HDR. Your negative, untouched. FULL MANUAL Shutter speed, ISO, exposure bias, focus and white balance, each on its own precise dial with real photographic stops. Lock any parameter, keep your settings between sessions. TOOLS THAT MATTER - Focus peaking, zebra stripes and a focus loupe - Live luminance histogram - All lenses including the 8x sensor crop - RAW exposure brackets (hold the shutter) - Subject tracking, AE/AF lock, horizon level - 1:1, 4:3 and 16:9 framing; the DNG always keeps the full sensor - Optional watermark and an Instagram-ready story card - Optional geotagging QUIET DESIGN A monochrome interface that stays out of your way, rich haptics and signature sounds. Photos go straight to your library; the app collects nothing about you. FREE, HONESTLY No ads, no subscriptions, no locked features, ever. If f/64 saves you a shot you love, there is a voluntary tip jar in the settings. Named after Group f/64, Ansel Adams and friends, who believed a photograph should be sharp, honest and made by hand.
