My new Mac has a few tricks in the photo software dept, which I've been messing around with in my spare time - of course I have HEAPS of spare time - and the results are pretty cool. This one is a neat little filter in PhotoShop which makes a nice image look even more dramatic. Here's a couple of examples (click on the pics to enlarge).
