GREAT Little Program!!!
If you like the background image softness you get with long lenses (especially in portraits) this is the program for you!!!!. Only took about 10 minutes to figure how to make it work (although it could use some sort of quick built-in tutorial) and the results are truely remarkable.
A heck of a lot cheaper than a 300mm lens!!!
