Shooting Modes

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.

P
Program AE

Camera selects exposure automatically. You keep control of ISO, white balance and effect. Perfect for quick street photography.

Av
Aperture Priority

Set the aperture; the camera handles shutter speed. Control depth of field in creative compositions.

Tv
Shutter Priority

Set shutter speed; the camera manages aperture. Freeze fast action or blur motion with intent.

M
Full Manual

Total control. Drag ISO, shutter, WB and aperture dials vertically. The Camera2 API exposes every sensor parameter.

Snap
Snap Focus

Pre-focused at 1 m, 1.5 m, 2.5 m or hyperfocal. No hunting, no hesitation. Shoot the moment. The GR way.

Film Simulations

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.

Custom Film Recipes

Stack contrast, saturation and sharpening on top of any base simulation. Two personal recipe slots — recall either from the effect wheel in one tap.

Custom Film Recipes

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.

Precision Controls

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.

Exposure

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.

ISO 100–256001/4000s–30s ±3 EV CompTonemap Curve
Focus & Metering

Tap-to-focus with GR-style corner brackets. Five modes including the signature Snap pre-focus. Four metering patterns — Multi, Center, Spot, Highlight.

AF-SAF-CMF SnapInfinity Spot MeterHi-Light
White Balance

Seven presets plus Auto. Applied at capture via Camera2 CONTROL_AWB_MODE — accurate colour science at the sensor level, not a post-process tint.

Advanced Overlays

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.
