colors can not be defined objectively -- the spectrum response curve of the film or CCD are different from rods and cones in our eyes. Even more, each person sees different colors from each person. So you can always find pictures 没经过任何加工 but have spectrum properties you need.

While your pictures are very colorful, the colors in 薛野's picture No.1 are quite uniform, which exclude out the possibility of 各单色频道的HISTOGRAM分布可能极其不同; Colors on 薛野's picture No.2 are quite distorted because most of us agree that the color of the the sky is blue instead of purple.

Although I believe 薛野 manipulated his pictures with software, it is very difficult to provide real evidence. Even we don't use software, we can always shoot the photos at different season, different light conditions, or use different cameras or different films. The worst thing is not lying, but presenting only partial truth.
