We finally got some much-needed rain here. This is an area that floods naturally with heavy rains and then slowly releases the water into the flood-prone Russian River, to help mitigate flooding. Once or twice a year there is a rain heavy enough to flood it to the right level for good photography, followed by a clear night that will allow ground fog to form. By tomorrow the level will be marginally low, and it will probably be cloudy instead of ground fog.
Canon 5D Mk III, 70-200 f/2.8 at 70. Big Gitzo with Wimberley II. ISO 1600 (should have been lower), f/9.5 1/500 sec. Full frame. Basic LR adjustments then to PS CS6 for some darkening of the highlights and lightening of the shadows, with Nik Detail Extractor, set not to give so much detail as just a slight shadow-highlight balance.
The horizon looks slightly curved but it's an effect of the trees on the right and left being a little closer than the ones in the middle. I always debate about fixing it but it isn't really possible because it isn't really curved -- there is a discontinuity on both sides.
