**v2.2-preview.1 (main):** three independent entries: FL23 installs/checks, LUT imports/restores one slot, and Recovery performs complete rollback. Both installation orders are supported. Includes the service-first USB connection fix; changes and validation.
**English** · 简体中文
For **Sony A7C II / ILCE-7CM2 firmware 2.01**, choose the workflow:
| FL2 / FL3 | Custom LUT / DCP | Recovery |
|---|---|---|
| Install and verify | Reference file to camera / slot restore | Complete rollback |
| Prefer **`.\FL23.cmd --help`** for CLI; double-click `FL23.cmd` for desktop | **`python lut.py import "look.dcp" --name "Classic Neg." --slot 1`** | **`python recovery.py --help`** |
**Preview: v2.2-preview.1** · Changelog. Previous non-preview release: v2.1.
Download standalone `lut.py`, standalone `recovery.py`, or the complete tools ZIP from the preview release. Original DCPs remain a separate download. FL23 v1.0 release.
Setup and Windows/macOS commands. FL23 retains its existing launcher, interface and installation flow. LUT/DCP and Recovery are CLI-only, with 64-bit Python 3.10+ and no Tkinter/CMD dependency.
LUT conversion, backups, actual writing/full readback, reload checks and restoration are implemented; no AI or prior FL23 installation is needed. One Windows camera passed an existing-six-look slot update, preview/photos and standalone reload verification. Stock first-install and Mac USB remain untested. The default color bridge is a shared one-scene approximation, not full DCP fidelity or a Sony-signed update.

## Film look comparisons
Camera JPEGs, resized, arranged and labelled only; no exposure, white-balance or color edits. Capture settings vary, so these are visual examples rather than controlled measurements.
Each scene shows three separate comparison images in order: **ST / FL / FL2 / FL3**, **ST / NC / CC / NN**, **ST / E / GR Positive / GR Negative**. Read each grid top-left, top-right, bottom-left, bottom-right. NC = Classic Neg., CC = Classic Chrome, NN = Nostalgic Neg., E = Eterna; Astia is not included.
Download all 19 full-resolution comparisons (about 152 MB), including the first scene’s extra ST comparison and the overview.
