For No Reason Here Is A Library Story

Photo-editing is not something I do much of.  So forgive me whoever this still belongs to (somebody's film project here in Springfield I take it), but I decided to play with your lighting in photoshop to see what I would do post-production. I had two goals, one was to improve the overall contrast and saturation, which is easy enough, but secondly I wanted to see if I couldn't fake a lighting change as though either the window light or the interior fixture light were dominant over the other. If I weren't working with a facebook jpg the quality I might be able to find out if it's possible to do it without the artifacts all over. On each I used a blue or red curve-corrected layer set to "color" blend on top of a channel extracted from either the blue (window) or the red (ceiling fixture) channel, which then had an opacity of 95% or so on top of the original layer.  The resulting color is a little flat on the alterations, looks like basic cable's use of chroma subsampling (where they preserve the black and white value but compress the color ranges, which is why when somebody has a five o'clock shadow it looks like somebody rubbed grey makeup on their face).

I like the idea of the blue one best but it's just not very good.

The red one wasn't a far leap at all, I may go back in on it later when I figure out how to do range-based (highlights, midrange, etc.) adjustments.
