This is a tool to rate CR3 files (Canon RAW 3) and write these ratings directly to the exif data of the CR3 and JPG file. It is useful for photographers who want to rate their images before importing them into a photo management software (Lightroom, Darktable, etc.).
The tool displays the image and allows the user to rate it with a number from 0 to 5. The rating is written to the exif data of the CR3 and JPG file. The tool is written in Python and uses the Customtkinter library for the GUI. The tool is still in development and has some bugs and performance issues. (See TODO section for more information)
It needs exiftool to be installed on the system. You also have to shoot in RAW+JPG mode, because the JPG file is used to display the image. The rating is written to the CR3 and JPG file.

This tool was developed with Python 3.12.2 and tested on Fedora 39. It should work on other Linux distros and Windows as well, but I haven't tested it.
If you want to contribute, feel free to fork the repository and create a pull request. The Tool should also work for other RAW formats as long as it is supported by exiftool, but I haven't tested it. If you want to use other RAW formats, you have to change the file extension in the code, because it is currently hardcoded to CR3.
