Here are five renditions of one photo from The Mill of Kintail. The first is the original, unretouched version.
The next one has my usual adjustments that better reflect what I'd like the photo to look like. I tend to saturate the colours a lot in these drab winter photos.
This is the same as above but highly sharpened. Look how much sharper the tree branches are: perhaps too much, but it was an experiment with highpass sharpening.
Sometimes, a young fella just wants to play around and see what pops up on the screen after applying a filters at random (next two photos).
