It's really old asphalt. Hasn't been re-oiled in years. It's also shot in very early morning light...if you can call it that. Well before the sun came over the mountain. I had the metering set to the middle setting (not point-of-focus and not whole frame) so I think the camera got a little tricky putting a little more light on the background. Would have looked a lot darker had I metered only on the iris. I think??
Thanks William. Neat thread and very worthwhile push.
