This demonstration serves two purposes; it shows the importance of post-processing in general, and also demonstrates some of the programs I use (or rather, the results they produce).
Sure, it's easy to spend hours on just one image, but here I wanted to show what can be done quickly and easily, and what a difference it makes. Certainly I could have improved the image further, in particular the choppy water annoys me, but that's not what the demo is about.
As for artistic choices, there's no avoiding them; that is to say, what looks good and proper to me may not be what you would do. Still, I did not seek an "artistic" look here, but to merely enhance the image.
