Mississippi River, Mud Lake
When I took our dog for a walk to the Mississippi River this morning I was almost tempted to leave the camera at home. It was just a gray and cold day. I hardly ever go without a camera to the river and I was glad I didn’t change my habit today. The photo was taken from almost the same spot as the one in my last post, which I called “Dynamic in the sky”. Well, there was no dynamic in the sky at all today, but the cold temperatures we had earlier this week, followed by some warmer weather, had broken up some ice upstream and a lot of drift ice was piled up. The river is about 2.2 km (1.375 mi.) wide at this point, but the Wisconsin side looks much closer due to the compression effect of the 200 mm lens.
Another occurrence that had an impact is heat shimmer. The cold air above the ice is mixing with warmer air and makes it impossible to see the ice on the other side of the river really sharp. I shot this with f/8 and focussed on the piled up ice on the Iowa side of the river. A smaller aperture, like f/16 wouldn’t help a bit in this matter.
Snow, ice, and a gray overcast don’t go very well together and in order to make this image work I left the white balance a little more on the colder side.
