Here we go Shankar..
It was pleasant surprise to see lots of action on stagnate water. To start with ‘Algae’ at the bottom was holding some sort of bubbles, occasionally letting one or two bubbles which formed hemisphere on top of water surface. I was trying to capture bubbles locked with algae and also bubbles floating on water surface. It was after a while that I realized reflection on floating bubbles formed nice pattern when out of focus(first pic).
And then bursting bubbles caught my attention. After several failed attempts to match bubble burst with click, I was lucky enough to capture this shot where we can see bubbles locked at the bottom and also ripple created by the burst. (Just for records, this was captured approximately after 0.024 milliseconds after the bubble burst!!! Just kidding
) Looking forward to explore more!
