Was watching the Bourne Supremacy last night. The entire movie has for want of a better term, a green tonality to many of the scenes. What you'd expect to be grey concrete has a green cast, everything has a very metalic green/yellow feel to it, but the skin tones all look pretty much normal.
It sort of has the feel of sodium vapour lamps in a way. Very much like the way the 'inside of the machine' was shot in the Matrix, if I remember well, too.
This image has much of the same tonality going on. Any suggestions, pointers, or guideance on how to attempt that sort of feel in an image ? What are the general approaches or techniques used for that sort of retouching ?
