Features & Capabilities

Measure light. Choose where to expose. Control your image. Spot meter for film and digital photography. Simplified Zone System mode for precise, intentional exposure.

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.

User Reviews

Maybe this app can be more useful with future revisions. For now it seems the most value is for determining the number of stops between dark and light to stay within the dynamic range of your selected film. To use the zone system effectively one needs to be able to measure the value (EV) of the brightest highlight, or the darkest shadow where details are to be retained, and to place that on a desired zone (e.g. zone VII/VIII for highlights, or zone VII/VIII for shadows). Then with your ISO set, use the corresponding shutter speed and aperture associated with the selected zone. This app just makes whatever you measure zone V and subsequent measurements are based off of that. That means that in order to effectively place everything in the scene in the proper zone you would have to always point the spot meter at something that’s actually neutral gray (zone V). Without the ability to read EV, place it on the desired zone and then select your desired shutter speed and aperture combination, this app has little value.

I don’t get it, for zone system controls one needs to read an important shadow and then place it on the zone scale. For this example point at a shadow which becomes the reference or zone V. Unless I am missing something I can’t find a way to place the reference reading at say zone III. Without being able to place a shadow reading at say zone III then any other readings are useless. Correct me if I am wrong. With a spot meter I point at an important shadow, place that shadow, say zone III, then read the highlights. With the shadow placed at zone III then the highlight reading will fall at say zone VIII. With that N-1 processing would be needed. Can the reference reading be placed at say zone III? If not what is the point.
