First off, here's the full-color jpeg that I started with:
|ISO 200 20mm f/3.2 1/320sec|
Cropping. A bit of lighting adjustment. Switch to monochrome - I think this is a much more interesting image. At first it was the color that caught my eye, but it's the pattern that's most interesting. I wish I could have take 10 more like this, really isolating the wheel.
