Re: [Avid-L2] Color in import.

That was my doubt, because mathematically I didnt realize if for scaling
0-255 into 16-235 some colour data was lose.
I usually work importing as RGB because I check the colour with a matrox
mini, so in the TV I see exactly the re-scaling of 16-235 to 0-255.
Thanks a lot for answer.
