Breaking apart

What you're looking here is the Leptothrix discophora bacteria broken apart by rain drops. Maybe many of you know this already, but this bacteria is basically a natural oil stain that forms in small ponds during rain. The difference between this kind of oil stain and that produced by the fuel spills that we see so often in the urban environment is that, once hit by any object, the natural oily sheen breaks apart permanently, while the fuel spill flows back together. Needless to say, it was amazing to watch this happening and I had only seconds to shoot it. I consider this one of the more unique images (not that I have many) in my portfolio and I'm quite fond of it. The section you see here was larger than 4 inches, so I hope it belongs here.

450d, 70-200, f4 and handheld as I didn't have enough time to make the whole setup for a proper shot. But it came out quite nicely and I'm looking forward to have the chance to shoot it again. And yes, converted to b&w.
