B/W & Ferns

I've been playing around a little with photoshop to convert my digital color images to black and white-as I've written before, the woods right now are so green, too green, so I start to look for textures and patterns instead and it matters little what the actual subject is.  Ferns are cool.  iphoto does a good job in B/W conversion, but I thought I try PS and see if it could be better using color channels.  It is, just a few more steps.
