Set the threshold to a starting value (let's say 15), then click on a white part at the edges of the image. But I'm not quite satisfied with the resulting selection: it selects most of the area I want but not enough of the greyish shadow below the chin. So I adjust the threshold to 50 and click again. Still not enough, set to 90 and lick again. A bit too much, set to 80 and click another. Almost there, set to 85 and click. Set to 83 and finally voilá. > > That involved a lot of clicking and typing though. ¿Is there a quicker way to do this? Ideally I would like to see a live update of the selection as I change the threshold, so that I can simply drag the slider or scroll the mouse wheel until it's perfect. > > Maybe I'm simply using the wrong tool and there's are completely different inroads to achieve this. I'd like to know about those as well.
I just did some heavy image effects, like denoise, selective gaussian blur and similar stuff. Gimp was able to use all 4 cores of my CPU at the same time. Amazing. It still takes a few minutes depending on the effect and effect strength, but without multithreading it would've probably taken about 4 times as long.

“This new development version of GIMP is a bit of a game-changer as it arrives with some long-anticipated CMYK-related features. The way they are implemented will make some users happy, but some users might feel annoyed. It’s got to do with early binding vs late binding…”
