One of my favorite Photoshop plugins is Fractalius. It is a fun plugin to play with and create very interesting results from all sorts of imagery. Lately, I have been using it on some winter photographs to create abstracts, such as the Fractalius results on the snowdrift above, or I have been applying it to some of my winter trees, silhouetted at the edge of day, for an alternate version of those images. I quite like the results of using Fractalius on some of these landscape imagery. Hope you do too!
