Python Plug-in for GIMP3: exec_raw_forge_g3

[yasuo (Ohnishi, Yasuo)]

I have bug-fixed this plug-in (ver. 0.1a). If you already downloaded this plug-in, please re-download it.

Hi,

I made a new GIMP3 plug-in which enables users to use RawForge and ART in conjunction. RawForge is the cli version of FOSS AI denoiser RawRefinery and is available in Linux, Mac OS and Windows, where RawRefinery is not usable on Windows yet.

Introducing a new FOSS raw image denoiser, RawRefinery, and seeking testers.

Hi all, I’ve been working hard producing RawRefinery, a raw image quality enhancement program. Currently, it supports image denoising and some deblurring, and I have plans to support highlight reconstruction and more. The application works best using CUDA or MPS, but can be run on CPU, and it saves its results as a DNG that can be edited in your favorite raw image editing program. Here is an example of its denoising performance on an ISO 102400 photo! [Screenshot 2025-12-15 at 10.05.38 AM…

@agriggio published the instructions of using RawForge and ART together in the site below.

https://artraweditor.github.io/AItools

However his method uses Posix shell script and Zenity, so it is difficult to apply it to Windows environment.

My plug-in replaces the shell script and Zenity to enable using them on Windows, however it is also usable on Linux and Mac OS. In other words, it may be said that using GIMP3 as an image processing platform, my plug-in enables the integration of RawForge and ART.

How to install it

1. Install RawForge following the instructions below.

https://github.com/rymuelle/RawForge
For Windows users, the instructions are below.

Introducing a new FOSS raw image denoiser, RawRefinery, and seeking testers.

@Jandren To all, but particularly windows users, I made a new test branch that uses the library tifffile instead of pidng, which should work in windows. If you want to test it out (it’s only CLI based at the moment, so suitable for the Lua script or potentially power shell, you can try it out like so: python3.12 -m venv test_tiffile . test_tiffile/bin/activate git clone -b feature_save_with_tifffile https://github.com/rymuelle/RawForge.git pip install RawForge/. rawforge TreeNetDenoiseSuperL…

2. Install ART, if you don’t have installed it yet.
3. Download my plug-in from here, and install it in your GIMP3 plug-in directory.

exec_rawforge_g3_v0.1a.7z

4. Install Adobe DNG Converter, if you want to decode Nikon HE compressed Raw files. In Linux install it using wine.
5. Setup config.ini file in the plug-in directory according to your environment.
   Default parameters are below.

[Python path for rawforge] is python interpreter path of virtual environment for RawForge.

[model for rawforge] is the model name used by RawForge. If your system has no GPU, it is recommended to use reeNetDenoiseLight or TreeNetDenoiseSuperLight.

[device for rawforge] specifies RawForge executing device. cuda for NVIDIA GPU, mps for Apple ARM chip PCs and cpu for no GPU PCs.

[lumi noise for rawforge] and [chiroma noise for rawforge] specifies the amount of noise to add back to the denoised result. See following posts.

https://discuss.pixls.us/t/introducing-a-new-foss-raw-image-denoiser-rawrefinery-and-seeking-testers/54778/68

If you want to use Nikon HE compressed Raw files, set [Decode Nikon HE Raw] True.

Start the plug-in

After the installation, users start this plug-in from [File] > [Apply RawForge to Raw and import it with ART…] in GIMP3 menu. If you use GIMP3 Flatpak version, start GIMP3 with “–socket=session-bus” option to allow it to communicate with ART.

Select target file.

Now denoising.

After denoising, ART UI will appear.

Closing ART UI, edited image by ART will be imported in GIMP3.

This is really cool! Is there a place I can link to share this with people?

[yasuo (Ohnishi, Yasuo)]

Thank you!
