Store description excerpt
Worevo is a precision Zone System exposure computer for film photographers who meter with a spot meter and develop their own film. Enter your readings, place one on the zone scale, and Worevo instantly maps every other reading across all eleven zones — showing you exactly what your scene will render before you press the shutter. The Scene Range screen calculates your subject brightness range in stops, your N-value development adjustment, and the development time scaled to your chosen film profile. The EV Wheel — a three-ring rotary dial — lets you set aperture, shutter speed, and ISO with a single rotational drag, with aperture-priority and shutter-priority lock switches built in. For long exposures, the Reciprocity screen applies a profile-specific power-law correction and plots the result on a draggable log-scale curve so you can see exactly how far your exposure shifts. Worevo ships with ten built-in film profiles spanning black-and-white and colour emulsions, and lets you create custom profiles with your own measured reciprocity exponent and normal development minutes. Save up to forty named setups as calculator memory registers — reload any scene complete with its full development plan, no account or internet connection required. The Zone Atlas gives you an eleven-zone visual reference with computed gray swatches and per-zone detail cards. Haptics, third-stop increments, and a configurable highlight target zone let you tune the tool to your workflow. A darkroom-inspired instrument display keeps every readout legible at a glance. Worevo is a self-contained analog calculator — no camera, no photos, no cloud.
