image-processing-lxm

Personal resources for image-processing which include topics like :

  • photography
  • cinematography
  • vfx

Warning

The package is not fully designed for public consumptions so use at your own risks. I can deploy major "breaking" changes at any time without notice.

content

You can find 4 software components:

  • libraries: collection of reusable code
  • clis: command line interfaces programs
  • scripts: entry point mixing the usage of libraries and clis
  • plugins: to be used in other software
tool description type tag
raw-to-dng.py batch converting raw files to dng script photo
raw-exr-converter.py batch converting raw files to OpenEXR, including debayering script photo
rw2-to-dng.py batch converting panasonic raw file to dng (personal need) script photo

Each tool should come with its own documentation for details.

usage pre-requisites

Most tool (except plugins) will require python and some dependencies.

  • uv is installed
  • you don't need to install python as uv will manage it for you

usage

Project is managed through uv.

Assuming uv and git are installed and available on your system, open a terminal and execute the following commands:

cd path/you/want/to/download/the/project/to
# the git clone step can be replaced by a manual download of the repo
git clone https://github.com/MrLixm/image-processing-lxm.git
cd image-processing-lxm
uv run ./scripts/raw-exr-converter.py

You will usually to edit the global variables in the scripts to replace with path for your system. You can also directly use the clis instead of the scripts wrapper.

If that can help I recorded for someone a quick video that explains how to use raw-exr-converter.py: https://youtu.be/-w_OqmZ0-NU
