Q: What do these look like when you first find them and before cropping and other digital enhancements?
A: These are before and after versions of "Rainbow Bridge".
Q: Do you always have to aimlessly wander cold, wet streets or parking lots looking for these things? Why not just place a few drops of motor oil yourself, either closer to home or better yet, in a warm indoor studio set-up?
A: I get asked this all the time, which frankly surprises me a little. Searching on foot and discovering a prime specimen is half the fun; almost like finding a precious stone or a fossil! And it's not completely random; there is a methodology to this. I try to frequent locales where leaky, clunker cars congregate, for one. Meanwhile, unless it really detracts from the image, I don't remove most road debris or dead leaves before taking pictures. Surreptitiously dropping toxic oil on damp ground and waiting for an asphalt nebula to form would be both cheating and illegal.
