FWIW, the one in post #424, Whisky Sunset, is a color negative.
In a nearby town, one of the banks on Main Street has brushed aluminum exterior wall panels. I shot somewhat down the wall and the light vertical lines are where the panels meet.
Tommy, yes, yours is VERY abstract and TOTALLY minimalistic. So much so that I don't seem to see a picture at all... Maybe it shows up the moment I post this, if so, I apologize in advance.
