Shooting past a second? Pick your film stock — Tri-X, HP5 Plus, T-Max, Portra, Acros, and more — and Actinic corrects your exposure time for reciprocity failure using published manufacturer data, so your night shots and long exposures come out right the first time. Included: • Full-stop exposure wheel with Sunny 16 quick-set • Reciprocity calculator with 3 built-in film stocks • Save up to 3 camera + film presets Actinic Pro unlocks the full 12-stock reciprocity library, unlimited saved presets, and third-stop precision to match modern camera dial clicks exactly — one-time purchase, yours forever.
