In Photofiltre, it's dead easy to extract the gray tones from an image to boost up the colours. It's often better than just increasing saturation or so.
But since I have Photoshop CS3 I'd like to do it there. It must be possible to do something like that too. But how?? I just can't find the right way?
Anybody here knows the answer?
Select --> Color Range or do some magic with Calculations to create a selection based on luminance.
