No Big Thing

Lovely rendering and composition. What is the source of the processing?
 

Well, in GIMP I did an automatic white balance and then a color enhance and an unsharp mask, but the unsharp mask with dark pictures makes them very grainy. So I tried the descpeckle filter to try and smooth that out, if you use a filter radius of say 5 and turn off the adaptive mode, this is what comes out. Not really descpeckled, but cool.
