Moving the Sterling Engine around to position it for shots, I caught the reflection of the brass wheel off the top of the base in my camera's live view. I thought it looked interesting enough to stop, compose, and take some shots to see how it would turn out.
I like how it's pretty much the polar opposite of tack sharp. It offers a dreamy impression of the Engine's flywheel and piston rod instead of a realistic representation.
It's Monet instead of Courbet, and not an area of photography I've considered.
But maybe I should.
