HushBlur is a light meter designed for film photography. Whether you are shooting with a vintage rangefinder, a medium format TLR, or any old camera that don't have light meter, HushBlur provides the accurate exposure readings you need. This is a native light meter for Android built to turn your smartphone into a dependable, professional-grade exposure tool.

► Necessary But Simple User Calibration for Accurate Results
Because every Android sensor "sees" light differently, a one-size-fits-all app can’t be truly accurate. HushBlur includes a quick user calibration tool to ensure the app perfectly matches your specific phone hardware.

Easy Alignment: Spend a moment matching HushBlur to a trusted source (like a handheld meter or a camera you know is accurate).

Set and Forget: Once calibrated, the app handles the math for you. You get a reliable exposure calculator tuned specifically to your device, ensuring your 35mm or 120 film is exposed correctly every time.

► Features for the Manual Workflow
The interface stays focused on what matters when you are framing a shot:

Spot-Weighted Metering: Tap anywhere on the preview to meter for highlights or shadows—the ultimate tool for the Zone System.

Incident Metering: Measure the light falling directly on your subject using your phone’s ambient light sensor (on compatible devices).

Exposure Note Keeping: Log your shutter speed, aperture, and ISO for every frame. Use Note Filtering to review your technical data after the film is developed.

Priority Modes: Quickly toggle between Aperture and Shutter priority for your manual lenses.

► Native, Fast, and Private

Native: Built natively for Android, so it is responsive and light on your battery.

Private: No internet required and no data collection. Your notes stay on your phone.

Zero Distractions: No intrusive popups for reviews or ratings. I believe a tool should work for you, not the other way around.

The Story Behind HushBlur
I started this project because I was tired of the guesswork. Most film photography apps are simple ports that assume every Android device has the same sensor. I built this because an analog tool should respect your specific hardware.

Try the free apps first.
There are many free light meters in the Play Store. If one works perfectly for your phone, that’s great! But if you find your exposures are inconsistent or the UI feels laggy, come back and give HushBlur a try. I’m building this for the enthusiast community, focusing on software that works rather than just sales.
