Just been for a bike ride - lent my bike against the wall and was fascinated by its shadow. Have downloaded Topaz Restyle this week - Northy mentioned it. It has so many choices but ended up with this high contrast shadow - moved a few sliders around and Ta Dah!
Wonderful shadow! Love the effect here. I have also been using Topaz Restyle and really like what it does. I found this article on it very interesting - http://tinyurl.com/ncxx2bo.
