The PhF plug-in also allows to directly open. You can also pass a file name as parameter to the GIMP AppImage, just like with the standard GIMP. The second line starts GIMP from the AppImage. The first line with the environment variable assignment is used to tell GIMP where to look for the PhotoFlow executable.

Of course you need to replace the paths of the photoflow and gimp AppImages with their actual paths and full names on your system. In order to start the GIMP AppImage and let it find and use PhotoFlow for opening the RAW files and/or run as a filter on the existing layer data, open a terminal and type the following:Įxport PHOTOFLOW_PATH=$HOME/Applications/photoflow.AppImage In the following I will assume that the AppImages have been downloaded into the $HOME/Applications folder, but any other folder on your filesystem is equally good. The latest GIMP and PhotoFlow AppImages can be downloaded respectively from here and here (you need to grab the most recent version).

In this follow-up, I will show how to run GIMP and the PhF plug-in under Linux using the AppImage packages. Every aspect of the RAW processing can at this point be modified and tweaked, or new adjustment layers added to further edit the RAW image.Yesterday I have briefly described the new PhotoFlow GIMP plug-in. The plug-in will in this case read the name of the input RAW file as well as the value of all the RAW processing parameters from the meta-data stored in the GIMP image, and will restore the RAW processing in the state as it was when the image was sent to GIMP. Let’s choose for the moment the first option, Edit current. If the configuration meta-data is found in the selected layer, the PhotoFlow filter gives you the choice between starting a new edit (corresponding to the Create new option, in which case the input pixels will be taken from the selected layer and the output will be sent to a new layer above the selected one) or continue editing the current layer (corresponding to the Edit current option, in which case the input pixels will be taken from the layer below the selected one and the output will replace the contents of the selected layer). What does this mean? When the plug-in sends the pixel data back to GIMP, it also saves the editing configuration as a meta-data blob in the GIMP image structure, so that it can be retrieved when the same layer is edited again with the plug-in. The PhotoFlow interface will open up with two pre-loaded layers, one for loading the RAW image and the second one which applies the RAW processing: Instead of opening the file directly, GIMP will call the PhotoFlow plug-in and pass the file name to it. The loading plug-in is very easy to use: launch GIMP, go to File → Open, select a RAW file from disk and hit the Open button.

The text is still work-in-progress and not yet complete, however I would appreciate any early feedback on what is already written, so that I can tweak the rest of the text according to the comments and suggestions already received… The PhotoFlow GIMP plug-in

This topic is intended to be a draft for a blog post or article about the usage of the PhotoFlow GIMP plug-in.
