Halcyon Camera

v3.2: multi-frame long exposure, slow-motion up to 240fps, Live Photo, ProRes 422 HQ + Apple Log video, and a Halide-style focus loupe.

Halcyon brings the soul of film to your iPhone.

Twelve hand-crafted film stocks — Kodak Portra 400, Cinestill 800T, Velvia 50, Tri-X 400 and more — each with the temperature, tone curve, grain, and halation of the real thing. Apply them live, before you take the shot, and what you see is exactly what you get.

REAL PRO CONTROLS, ONE-HANDED. Full manual ISO, shutter, focus, white balance, and exposure. Tap to focus. Long-press for AE/AF lock. Pinch to zoom. Volume buttons fire the shutter. Lens switcher for ultrawide, wide, telephoto. Halide-style focus loupe magnifies the sharpness plane as you rack focus. Histogram, waveform, focus peaking, zebras, false color, horizon level — when you need them, hidden when you don't.
