I ask this because if you look at the wall below the window at the far end (bottom of the picture), it has a definite (quite strong) blue hue - while in the lower picture it's much more neutral tone. This suggests to me that the picture was "too blue" initially. I'm not discounting the presence of more scattered light, but AWB can really mess with the color "perception" of a digital camera. I would want to see the RAW images before drawing the conclusions you reach. | |

Your analysis really interests me, and I'll certainly use that kind of approach on other image processing problems, thanks a lot for providing the code ! | |
