I'll have a closer look at the originals and especially the histograms. I did a little processing to try to decrease the very blue overall tone, and this may have added some exaggeration of area-to-area differences. I'll also post a higher- quality jpeg version to minimize posterization. This probably would have been a good scene, with poor overall contrast, to have shot as RAW. Oh, well, the weatherman says an additional 2-4 inches tonight, then 3-6 MORE on Weds, so I can perhaps re-shoot the scene.... --howard Oh yeah. Sensor spots. I noticed.
