I often needed this kind of plugin to add some depth to images and always used creepy workarounds to get my results. Yesterday I started thinking about the problem of dynamic blur radiants and now „Moderated Blur“ is available as a Python-Fu plug-in for GIMP.
This plugin enables dynamic transitions between blur radiants and can be used for a lot of camera- and optical effects (example). It uses a grayscale map to determine the blur radiant and can be configured with some options:
- Moderator: Select the layer that will be converted to greyscale and that will be used as the „blur map“
- Min Blur: The minimum blur, used in black areas of the map
- Max Blur: The maximum blur, used in white regions of the map
- Accuracy: The amount of different regions. Each region is blurred on its own so this raises render time.
- Order: Which blur intensity should be composited on top? Use Min for sharp edges and Max for soft transitions.
- Scale: Use logarithmic or linear blur radiants. Logarithmic blur starts softer and creates a nicer field of depth.
Installation
Download the script, unpack it an move it to ~/.gimp-x.x/plug-ins/
Usage
- Create a layer with grayscale content where white will trigger the highest blur radiant and black will use the minimum blur. Move it whereever you want in your layer stack, you can even set its opacity to 0.
- Select the layer to be affected
- Choose Filters -> Moderated Blur
- Choose the moderator layer you created, make other settings and start the process
- Optionally remove the moderator layer afterwards

Thank you very much!! You're doing an essential job for the development of open source software! The following points aren't meant as dogmas but as a clue, decide for yourself what you think could be useful in troubleshooting.
- Please...
- ...state name and version of your operating system / desktop environment
- ...state the version of the program you're using
- ...be detailed in what is happening and what you expected to happen
- ...try to provide some deeper information (like xplanetFX logs or the output of the program when started in a terminal window)
- ...speak to me as a human being, don't think I'm a bot.
Herzlichen Dank!! Fehlerberichte sind essentiell für die Entwicklung von Open-Source-Software! Die folgenden Punkte sind keine Dogmen, sondern sollen eher Anhaltspunkte darstellen; entscheide selbst, ob sie für die Fehlersuche hilfreich sein könnten.
- Bitte...
- ...nenne den Namen und die Version Deines Betriebssystems / Deiner Desktopumgebung
- ...nenne die Version des von Dir benutzten Programms
- ...beschreibe möglichst genau, was passiert und was Du erwartest, was passieren sollte
- ...stelle möglichst tiefergehende Informationen zur Verfügung (xplanetFX Logs oder die Ausgabe des Programms im Terminalfenster)
- ...sprich mit mir, wie mit einem Menschen, ich bin kein Automat.

Ich hab zwar keine Ahnung von Bildbearbeitung, aber das sieht ziehmlich geil aus 😉
