Black and white version
Thanks for your comments and encouragement. Yes, this is the 18-50mm EX Macro. I've been quite happy with it so far.
So, here's my attempt at converting the scene to BW. I really have almost no experience in this, so I feel quite vulnerable here. Still, I appreciate any comments or suggestions.
I used a Channel Mixer adjustment layer in PS to make the change. I didn't think to record the RGB percentages. That lone tree becomes even more significant here.
