Alien Skin Xenofex 2, Effects Plug-in Software for Photoshop, Macintosh & Windows.
Superb!
Xenofex is a collection of plugins for graphics applications such as Paint Shop Pro and Photoshop, it should also work with the free Irfanview.<br /><br />The collection comes with lots of presets and the interface is very easy to use, with a series of sliders in each dialogue box which when moved displays the end effect in a preview window.  My favourites of the plugins are Little Fluffy Clouds and Constellation but the Puzzle is nice and so is the Mosaic.  I often use Little Fluffy Clouds to replace a poor quality sky in my photographs.<br /><br />The quality of the applied effects is very high and gives an impressive finish to your images.<br /><br />These are great plugins to use and once you have them you will wonder how you managed without them.
