GrayZone - Light Meter

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.
