Re: Rheinfalls-Color & WB Problems


+1 @ artifacts ... I tried to push a bit too much playing with the blues/cyans before I noticed I had created a problem along the way.

The problem is that people think the light is homogenized to \"one color\" ... but it is more of a gradient as the angle of reflection changes from pointing at the cool blue sky to pointing at the warm yellow/red sun (time of day dependent). Items that are \"flat\" (i.e. consistent angle of reflection) like the house tend to only reflect \"one\" of the sources, whereas waterfalls, are anything but \"planar\".

Waterfalls by their very nature have part of them in a horizontal plane (the river/stream) and other parts in a vertical plane (the fall). Combine that with the churning of the water and you\'ve got a myriad of reflective surfaces pointing at a myriad of gradient color (sky, sun, foliage, etc.) For this reason, efforts @ a \"global\" color correction in mixed lighting is an unrealistic expectation, imo.

Take your scene and CRANK THE SATURATION TO 100% ... you\'ll see what colors are \"in play\". In this case, you can see the waterfall has areas that are BLUE (deep shadows where no direct sunlight reaches), YELLOW (areas that don\'t reflect up toward the blue sky), GREEN (areas that receive both blue & yellow) and \"white\" in areas that \"match\" the assigned WB.
