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.
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.
