What “calibrated preview” means here
Every preview on this site — and in GR Studio and the Companion app — is rendered by one engine, built against measurements of real GR cameras. When we say a preview is faithful, that's a number, not a feeling. The numbers are below.
| Camera | Firmware | Bundle | Measured basis | Status |
|---|---|---|---|---|
| GR4 | 1.10 | 0.1.0-synthetic | calibration in progress — basis published before launch | Calibration in progress |
| GR3 | 1.00 | 0.1.0-synthetic | calibration in progress — basis published before launch | Calibration in progress |
In short: we photograph controlled scenes on real bodies, compare the camera's own JPEG output to our engine's render, and publish the difference. The full method lives in the calibration programme docs.
Screenshot coming soon — One canonical frame, unprocessed vs recipe-rendered, split
One frame, one recipe: the camera's role and the engine's render, side by side.
