Professional
photography.
Distilled.
Every control deliberate. Every image intentional.
CameraGR brings the legendary Ricoh GR experience to any Android phone — manual controls, 15 film simulations, RAW capture and a UI that thinks like a real camera.
Five ways to
control the light.
From full auto to total manual. CameraGR uses the same mode system as the Ricoh GR — adapted for touch with vertical drag dials for ISO, shutter, WB and aperture.
Camera selects exposure automatically. You keep control of ISO, white balance and effect. Perfect for quick street photography.
Set the aperture; the camera handles shutter speed. Control depth of field in creative compositions.
Set shutter speed; the camera manages aperture. Freeze fast action or blur motion with intent.
Total control. Drag ISO, shutter, WB and aperture dials vertically. The Camera2 API exposes every sensor parameter.
Pre-focused at 1 m, 1.5 m, 2.5 m or hyperfocal. No hunting, no hesitation. Shoot the moment. The GR way.
15 looks.
Infinite stories.
A complete ColorMatrix pipeline processes every pixel before storage. Each simulation is a distinct character — not just a filter. Swipe the effect wheel to change look in one tap.
Your signature
look. Every shot.
Go beyond the 15 built-in simulations. CameraGR lets you build two fully custom film recipes — each a complete 19-parameter image pipeline layered on top of any base effect. Name them, dial them in, and access either from the effect wheel in one tap.
Every dial.
Every setting.
CameraGR exposes the Camera2 API through a UI designed for one thumb. Vertical drag gestures turn any dial into a physical control.
Full manual exposure via Camera2. Drag ISO and shutter dials vertically — the HAL enforces correct SENSOR_SENSITIVITY + SENSOR_EXPOSURE_TIME pairs. Tonemap curves for contrast.
Tap-to-focus with GR-style corner brackets. Five modes including the signature Snap pre-focus. Four metering patterns — Multi, Center, Spot, Highlight.
Seven presets plus Auto. Applied at capture via Camera2 CONTROL_AWB_MODE — accurate colour science at the sensor level, not a post-process tint.

Miss less.
Professional viewfinder tools that give you the data to nail the shot — invisible when you don't need them, instant when you do.
Live Histogram
Real-time luminance histogram computed from the YUV viewfinder stream. Know your exposure before pressing the shutter.
Focus Peaking
Sobel-edge detection highlights sharp edges in red, yellow, blue or white. Precise manual focus without magnification.
Overexposure Warning
A zebra-style alert fires when the fraction of pixels exceeding 240/255 luminance crosses your threshold. Protect your highlights.
Electronic Level
A horizon indicator driven by the accelerometer shows roll angle in real time. Keep your verticals perfectly straight.
Grid Overlays
Five composition guides — Thirds, Square, Diagonal, Golden Ratio — drawn as transparent overlays on the live viewfinder.
Aspect Ratios
3:2, 4:3, 16:9 and 1:1. A masked overlay shows the crop live in the viewfinder before you shoot.

your format.
