v2.2.0
GR4-LUTSmith 2.2.0 — the GR IV HDF
Put the look of a .cube LUT into your RICOH GR IV or GR IV HDF, in a window: no terminal, nothing else to
install. The app makes exactly the same firmware as the command line from the same LUT and choices.
New in 2.2.0: the GR IV HDF
- One file for both cameras. RICOH ships one 1.11 update for the GR IV and the GR IV HDF, and the firmware
GR4-LUTSmith makes now works on both. There is nothing to choose: start from RICOH's official 1.11 file as before. - Your look opens at 0 on the HDF too. Until now, on a GR IV HDF a personal look opened with RICOH's slider
settings for its slot (for example Contrast +3 on Positive Film) instead of 0. Now every slider starts at 0 and
grain is off, as on the GR IV. Tested on a GR IV HDF 1.11: works. - Nothing changes on a GR IV. A 2.2.0 file is the 2.1.1 file of the same looks plus only the HDF's slider
settings; a GR IV reads exactly what it read with 2.1.1. - Files made before 2.2.0: fine on a GR IV. For a GR IV HDF, build the same
look.jsonagain; Check a
firmware file (orcheck) tells you which files need it. - Never on a GR IV Monochrome or any other model.
The README (all 8 languages) also has a testing-status entry for colour after the curves (tested on a GR IV 1.11).
Earlier: 2.1.1 the guide in 8 languages; 2.1.0 several turns at once; 2.0.2 new app icon.

v2.1.1
GR4-LUTSmith 2.1.1 — the guide in 8 languages
Put the look of a .cube LUT into your RICOH GR IV, in a window: no terminal, nothing else to install.
The app makes exactly the same firmware as the command line from the same LUT and choices.
New in 2.1.1: the guide, reorganized and translated
- Find your way faster: the guide opens with what you want to do (use the app, use the command line,
build a shared look, check a firmware file, go back to RICOH's firmware) and takes you straight there.
Putting the firmware on the camera is now one set of steps for the app and the command line alike. - Read it in your language: 日本語, 简体中文,
繁體中文, 한국어,
Deutsch, Français,
Español, next to English. They use the app's own words and
the camera's menu words, so the guide matches what you see on screen.
The app and the firmware it makes are unchanged from 2.1.0; only the version number is new.
Earlier: 2.1.0 several turns at once; 2.0.2 new app icon; 2.0.1 Start fit works in the app.

v2.1.0
GR4-LUTSmith 2.1.0 — several turns at once
Put the look of a .cube LUT into your RICOH GR IV, in a window: no terminal, nothing else to install.
The app makes exactly the same firmware as the command line from the same LUT and choices.
New in 2.1.0: turns side by side
Where the fit starts often decides how close it gets, so trying several turns pays off. They no longer have
to wait for each other: each turn runs on its own processor core, so three turns take about as long as one.
- Choose how many run at once on the Fit page, from 1 up to one less than your computer's cores. The
app shows how many cores you have, the memory each turn needs (about 0.8 GB) and how long the turns will take. - Watch each turn: its own row with its start (usual, or random with its seed), a bar of its stages, and
what it is doing: waiting, the stage it is in, then its ΔE00 and whether it was kept. - Add turns while others run, with or without colour after the curves; they start when a core is free.
- Stop all ends the running and waiting turns and keeps the ones that finished.
- Results join the table as turns finish, always in turn order.
The results are exactly the same as running the same turns one after another; they are only ready sooner.
On the command line, fit and make take --jobs N to run up to N turns side by side (also for turns
added at "More turns?"). Without it, nothing changes.
Earlier: 2.0.2 new app icon; 2.0.1 Start fit works in the app.

New in 2.0.2: a new app icon, "Tempered curve": a steel bar bent into a film tone curve, in the colours
steel takes when it is tempered. Nothing else changes.
2.0.1: Start fit works in the app (in 2.0.0 it ended the fit at once).
