In the example below, the first image is the original plate in log color. The second image
has been converted back to linear color, and therefore looks more natural to the eye.
A Color–Mult node is applied to the log image and to the linear version with an
extremely slight red color.
Note: You are invited to view the online PDF documentation to see the color images.
It is difficult to gauge the result in the first image, since it is still in log color. The second
image lends a nice tint to the pink clouds (assuming you want pink clouds).
When the log image is converted to the more natural linear space, the “slight” red
multiplier applied before the conversion has completely blown the image into the
red range. This is bad.
