## GrayZone 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.

## GrayZone Reviews in United States

### ***** "Thank you for creating such a useful app."
This app is amazing. I honestly do not understand the low ratings or why more people do not recognize how useful this app can be, especially for photographers who understand the Zone System.
For someone who does not want to carry a dedicated spot meter around but always has a smartphone with them, this is an excellent substitute. It is also a fantastic tool for “visualization” how a scene might translate into black & white. Since we naturally see the world in color, it can sometimes be difficult to immediately recognize where different zones will fall within the Zone System. This app makes that process so much easier and much more intuitive.
Great job developing this. I am genuinely glad someone created an app like this, and in my opinion, it is worth every penny.
I also really appreciate that you chose not to make it subscription-based. Please keep it that way. Stay small, stay humble, and continue making great products. I will gladly support and recommend it to others.
By the way, I am a professor in the field of photography, and I would absolutely recommend this app to my students as a practical tool for learning and applying the Zone System.

### **--- "Could be better."
I like the idea of taking readings of different areas. But why not display the average of all? 

It needs work.

### *---- "Not really the “Zone System”"
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.

### *---- "No placement of reference reading."
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.
-- Deardorff 8x10, 2026-07-21

### ***** "Brilliant software"
Spot metering is such a great idea, but then combining it with the zone system is absolutely brilliant. You still have to learn about the zone system and what it does, but this little piece of software makes it really easy to see how much contrast is in your scene and what you might need to do in development. I also really appreciate it’s a buy once situation, instead of another damn subscription. Also that there’s zero privacy infringement. Well done!
