Ripple Patterns

I wandered down to the Nepean today, something I hadn't done for ages. This particular image was one I'd idly shot for sort of cutaway "coverage". Upon close examination, later, I noticed all of these stripey fringes to the watery shadows. Can you see them? I couldn't figure out where they'd come from at first ... until I realised that I had been standing under the motorway bridge. Extra 1 shows what you see when you look up. Enough said I suppose.

Anyway I have posted a few other "impressions" from the moment.

N.B. I have cropped the image so that the fringes are more visible on phones.
