Please forgive my lack of knowledge..

I'm finishing up a film, and the colorist has done everything from apple color, from a FCP sequence of quicktimes. The director exported all the .r3d files to .movs to edit with, then the colorist colored from that.

Now there are a few shots that are overexposed 1-2 stops, so I offered to bring down the .r3d files and re-export them. Its been working fine, I've been bringing down the ISO and everything has been looking better. But I just noticed that the exposure has been set to 1, not 0, and the "tint" bar is at -20. Are these automatically there for a reason? Or should I set them both back to 0? I'm afraid to touch the tint bar because the color looks fine the way it is, and I don't want to mess anything more or make things harder on the colorist.

I apologize again for my lack of knowledge, and thank you ahead of time for your patience.
 
An exposure of +1 will be pushing the image deliberately towards over-exposure. Tint is to correct for white balance from light sources that are not pure black body radiators. If the whites look white, then the tint is correct.

Ok thats what I was thinking, no reason to have the +1 exposure. But if the whites are white I shouldn't touch the tint right?
 
If the whites are white then leave the tint.

One more question.. Everytime I open up one of these .r3d's in REDCINE-X, the exposure is pushed one stop. Was this some kind of accidental in-camera setting? The ISO and color temp open up to what was set on camera, but so does the +1 stop.

And if thats the case, they've exported every clip like this. The final color graded version looks fine, aside from the few over-exposed clips i'm bringing down. But if each of these clips were exported +1 stop exposure, should I re-export them all over?
