Strange picture, this. It almost seems asif it was a table top composition, there are some strange effects with regard to depth-of-field and unexpected shifts in focus. Intrigueing, though, nice one.
Nice capture of our little snow storm, Greg. The overall image looks a little flat to me. I have been trying the method outlined by Ray Wearm in his article "Colour to B&W In Photoshop: ...", with some very good results. I use Channel Mixer also and his method is a good alternative.
