What’s New Version 3.2

New inverted UI color scheme Histogram repositioned to avoid interfering with the rest of the interface

Description

GrayZone reads light where you decide — not where your camera guesses. Built by Max of max&douglas — professional photographer with 25 years in editorial and advertising photography. Zone System Mode Measure a reference area first (Zone V), then check where the other tones will fall and their relative EV difference, for precise and consistent exposure. Real SPOT Metering Reads light exclusively in the area you select. Ideal for portraits, complex lighting and critical situations. Calibrated to render the selected area as neutral gray. Direct Exposure Control Set ISO before metering, like a dedicated light meter. Instant precise combinations of shutter speed and aperture. Exposure lock with AE LOCK. Half-stop support for finer control. MANUAL mode with over/underexposure scale. Essential Interface Live preview in your sensor's native ratio. NEW UI color inversion Shows only what you need. Nothing else. Complete Privacy No ads. No photos saved. No data collected or transmitted. For manual shooters — on film or digital. It does not replace your camera. It works alongside it.
