Heather moorland above Haworth (view large)
I am intrigued by the difference you can make to an image by some careful selective enhancement, and I keep experimenting with this. The art seems to be in not going OTT - you need a good eye as well as an understanding of what Photoshop can do. In this image I selected in turn the sky, the foreground and the middle ground and tweaked levels, saturation and colour balance on different layers, until I liked what I saw. I've also been trying different blending modes and in this case I used 'Colour Dodge' at about 50% opacity, just on the heather in the foreground, which added quite a bit of 'zing' to it I think.
Judge for yourself - the original image is here, it suffered from trying to balance the bright sky and much darker moorland, so that it all looks a bit dull. Any comments? I'm learning.
