SnapMeter-Film Meter & LUT Cam

SnapMeter – Professional Light Meter, Rangefinder & LUT Camera for Film Photography

Bring precise exposure memories back to your zone-focus cameras, point-and-shoots, and instant cameras.

Features the most natural photo and video capture with direct applications of Flog2 LUT and V-log LUT on the market.

Supports direct LUT application within the RAW pipeline, eliminating the hassle of RAW post-processing, combined with the smoothest gallery experience.

Core Features: 3-in-1 Professional Photography Tool

Film Light Meter + Zone-Focus Rangefinder + LUT Camera + RAW Camera


1. Professional Light Meter Interface (Light Meter)
Designed specifically for film characteristics, offering intuitive exposure previews:

Dynamic Zone Preview: Built-in zebra patterns and dynamic histogram (relative EV) for real-time tone control.

Supports AI portrait recognition and development preview.

Film Latitude Simulation:

Negative Mode: Real-time highlighting for ranges below -2EV and above +6EV.

Slide/Reversal Mode: Strictly monitors ranges below -2EV and above +2EV to prevent blown-out highlights.

Quick Controls: One-tap toggle for zebra patterns, AI portrait recognition, and preview options.

Grayscale Scan Preview: Real-time simulation of film processing and scanning in the upper-left corner to help quickly judge exposure intent. (Requires AI enabled)

2. Rangefinder & Flash Calculator (Rangefinder & Flash Calc)
Achieve accurate focus even with zone-focus cameras:

Projection Distance Measurement: Set your holding height and align the crosshair with the ground point of your target to quickly calculate distance.

Flash Output Calculator: Recommends optimal flash settings based on measured distance and Guide Number (GN), ensuring flash photos are never overexposed.

3. Pro Camera with 3D LUT Photo & Video (Pro Cam)
A highly extensible shooting system:

Pro Format Support: Built-in Flog2/Vlog and sRGB LUT formats for shooting photos and recording videos directly with 3D LUTs.

Main lens supports RAW format shooting. The app retrieves raw sensor data and performs RAW pipeline alignment and conversion to deliver the most natural photo style.
(Processing speed per RAW shot depends on device performance)

Supports selfie mode, custom photo imprints, and simulated film date stamps.

Supports video recording with LUTs including image stabilization.


Startup Settings: Customize the default launch interface to either the Light Meter or Camera.

Privacy & Technical Information
Microphone Usage: Audio is captured only in "Video Mode". The app will never eavesdrop or record in non-video states.

Hardware Dependency: Light meter accuracy depends on raw data provided by your device sensor; fine-tuning based on your device is recommended.

If RAW + LUT processing is too slow due to hardware speed, please switch to the JPG pipeline for shooting.

Additional Notes:

1.
If live rendering does not show in preview, manually force GL (Live Rendering) on in the 3x3 grid pop-up menu.
Fresh installations default to GLA for auto-detecting hardware performance.
If a crash occurs, live rendering will auto-disable and must be manually forced back on.

2.
The RAW pipeline is supported on the main camera lens only.
Bypassing computational photography RAW pipelines requires higher-spec main lens hardware.

3.
Due to heavy raw data conversion, the RAW pipeline does not support real-time preview rendering.
When using the RAW pipeline for shooting, preview tones will differ from the final captured photo.
