Lighting for 2d shots

well we are doing some compositing and colour tests. interesting problem creeps up.
we need to adjust the brightness and contrast for certain shots to make sure the characters come across.
problem is if the shot is within the same room and we are cutting from wall A to wall B would it be a big NO NO to have different shades or light levels?
coz i envisage a jump in surrounds (akin to a jump cut) and think it is a problem.

solution is to use the same contrast levels for all shots within the same continuity but in some cases the lighting seems insufficient.

you guys have any suggestions?

Are the room's layouts fixed? If not, you could apply additional props giving light where needed. Just an idea ...

actually the room layout is more or less fixed. what i can do is mess with the colours and look of things.
but what im afraid of is making a mistake or mistakes by making adjustments to scenes and then having an issue with discontinuity i.e. same room different lighting (usually would be an issue with close ups or close mid shots i reckon) with long shots its not that much of a problem (as long as the layout dosent re occur very often in the same set of shots)

am i making any sense?

Of course you do. To retain continuity, colour keys may be helpful. I'd suggest making small sketches of the various layouts you're going to use, or print out downsized copies of them, and roughly apply colour to those first. After you're done, place your colour keys next to each other, or pin them to a board at eye level. Take a step back and observe carefully. It should give you a good first impression of whether or not there are significant changes.
The guy who taught me background painting in school suggested painting thick black frames around the motifs - that way the colour you apply gets into focus more and it will be easier for you to concentrate on a motif and its colour design as such.

I do not understand why you can not take two different passes on your scene. Shift the color, or whatever you need to, on the second pass then join the best parts of both scenes.

Thanx Jab, your idea is something ill def keep in mind.

Wontobe. its not a question of what looks good really, its a question of ensuring that there isnt a jump in continuity really.

im already doing what you (wontobe) suggested because thats ideally my only choice. but i wanted feedback in terms of how sacriligious you guys think it is.
coz ive seen some films etc where this point is pretty much disregarded .
