Two weeks ago, it was frigid and there was snow, last week it thawed and the streams swelled with melting snow. I went to my favorite creek for a look. Inspired by another photographer’s images of flowing water, I tried closeups of the churning water. There’s a long exposure that shows the scene and silky water, then closeups of bubbles.
When I pointed my lens in the middle of the flow at a high shutter speed, it captured motion and streaks of bubble detail. Looking straight down into the water next the the flow, I could capture more detail, bubbles breaking, and the changing dark surface of the water. Click a thumbnail to see an image at a larger size:
