Selective decolorization is removing the color from parts of a picture. In this picture, I removed all the color from the background. For some reason there’s some noise that appeared when I uploaded it but it’s not like that in the master version.
It looks complicated but it’s actually a relatively simple process. Just open the picture you want with Gimp, then create a new layer.

Then go dow to the Mode dragdown menu and select saturation (make sure the new layer is selected). Then you can either use the paint fill or paint brush tools (or any other tool) to make certain areas appear black and white. It’s a neat trick that can really make some pictures look really nice. I did this one kind of quickly but with a little more time and effort, these turn out quite nicely
