Along with the Adobe filters coming with Photoshop Elements, the third party plug-ins can also be applied as smart filters.
In case some of the plug-ins supported by the "Smart Filters" script are installed in PSE, they appear in a separate menu (the supported plug-ins are listed below). You apply a plug-in by selecting it from the list, as shown on the screenshot.
Then, you can handle the applied "smart-plugins" exactly like the standard filters -- edit, hide, change blending mode, etc..
Please, keep in mind, though, that the smart plugins may behave differently from the standard smart-filters. Their reliability and ease of use cannot be guaranteed.
Below is the list of the third party plug-ins supported by the "Smart Filters" script:
- AKVIS Refocus
- Imagenomic Noiseware
- Nik Analog Efex Pro
- ON1 Perfect B&W
- Topaz photoFXlab
