Look pack 56

Look pack 56 for the Olympus OM-D E-M10 Mark I (firmware 1.4)

No firmware is included in this release. The builder downloads the official E-M10 Mark I v1.4 firmware from
the OM Digital Solutions server to your PC (you accept OM's licence first), applies our edits, checks the result
byte for byte, and writes the file for your SD card.

Quick start

1. Download om10mi-build.exe (Windows, no Python needed) or om10mi-mods-v56.zip (any system, needs
   Python 3.10+).
2. Run it: double-click om10mi-build.exe, or unzip and double-click om10mi-build.bat (Windows) /
   om10mi-build.command (macOS), or run ./om10mi-build.sh (Linux).
3. Read and accept the OM Digital Solutions licence it shows. The firmware is downloaded for you.
4. Enter your SD card's drive letter when asked (or copy the out/DCOLYMP folder to the card yourself).
5. Camera off, card in, hold OK and switch on, wait until the AF lamp blinks rapidly. Full steps in
   INSTALL.md.

A copy of the official firmware, for going back, is written to out/RESTORE/DCOLYMP.

What version 56 contains

• 14 film looks with their own colour matrix and tone curve, plus 4 new looks: Portra 400, Kodachrome 64,
  Ektar 100, Gold 200 (Picture Mode, SCP, Live View, RAW Data Edit Custom1/2).
• Contrast, Sharpness, Highlight, Shadow and Gradation really act on looks; SCP Contrast/Sharpness work on every
  look; Acros in RAW Data Edit Custom is black and white again.
• Per-sector colour editor (Hue/Saturation/Lightness, 12 colour-named sectors), per-look editor on the Custom
  page, looks selectable in RAW Data Edit Custom1/2 with their own rows, row titles/captions and new icons.
• Video recording limit raised from 29:59 to 59:50 (a single file is still capped at 4 GB).

Sample pictures (straight out of camera, Natural vs each look) are in the
README.

Checks the builder makes

• the downloaded file must be the expected firmware 1.4 (sha1 5a0703acadf27fde157a827d3b8c713a4d257fe1);
• the result must be sha1 0d4e1649cb930d39fc49a331d92840a7cbcbd83e, otherwise nothing is written;
• an optional SD copy only ever writes DCOLYMP/E1139999.BIN, and only on a drive that has a DCIM folder.

Known limitations

• The four new looks borrow the icon of an existing look (Portra 400 = Pro Neg Std, Kodachrome 64 = Classic
  Chrome, Ektar 100 = Velvia, Gold 200 = Nostalgic Neg); the names are shown correctly. Own icons are planned.
• Made and tested on a single E-M10 Mark I body. E-M10 Mark I with firmware 1.4 only.
• The exe is unsigned (built with PyInstaller from om10mi.py and patch/looks56.json), so Windows may show a
  SmartScreen warning; the zip with the Python launcher runs the same code.

Warnings

No warranty; installing custom firmware is risky. Update mode (hold OK while switching on) never runs the added
code, so you can always reinstall the official firmware from out/RESTORE. The licence attached by the OM server
prohibits, among other things, modifying the software; building and installing is your own decision.
This project is unofficial and not affiliated with OM Digital Solutions or Olympus.

Support

Free to use. If you like it, you can buy me a coffee on Ko-fi. Donations are
optional.
