I don’t know… actually, the instructions on how to properly install and run the plug-in are one of the missing parts of the article.
I’m in close contact with Partha who is preparing updated Windows and OSX packages with the latest PhF plug-in included and working out-of-the-box.
For the linux case, I plan to ask Thorsten to possibly update his gimp-edge PPA, but only when the RAW loading code is fixed at the GIMP level.
For the moment, I’m afraid that having Darktable installed totally blocks the PhF plug-in…
Yes, this is definitely the main step forward in this version, and also compared to other existing plug-ins.
One can effectively use the GIMP layers as placeholders for the various processing steps, keeping full non-destructive control on the way. Or you can mix edits with PhF, G’MIC and GIMP itself. For example, you can use the PhF filter plug-in to apply PhotoFlow’s shadows/highlights filter (directly derived from the awesome original Darktable module) to any existing GIMP layer…
