Recently I bought NikSoftware Filters, like Color Efex, or Silver Efex. Usually I use them from Lightroom4, and that’s okay for me.
Now I don’t own Photoshop, but I have installed Gimp 2.8.4, and from time to time I use various Gimp filters like G’MIC, or National Geographic.
But I was not able to use the NikSoftware Filter from Gimp as NikSoftware is shipped as Standalone-Executables, and as Photoshop-Plugins, but not as Gimp-Plugins.
Now there is a Gimp Plugin called PSPI which stands for Photoshop-Plugin.
I gave it try: I installed PSPI and registered the directory of the NikSoftware 32bit plugins. I even was able to invoke the Color Efex Pro 4, and it opened, but the image shown by Color Efex Pro 4 was corrupted.
So I gave up, and forgot about using NikSoftware Filters from Gimp, as I was quite happy using Lightroom and NikSoftware.
But as another user on Google+ asked about using NikSoftware from Gimp, I thought about it again, and then I found a nice Gimp plugin called ShellOut…
