Subject: Re: Digital sensors and white/colour balance.
does ACR just boost the blue channel to compensate and thereby making
the blue channel look noisier than the others?
The answer here is definitely yes. See my post in another thread on this topic with an example (look to the end of the thread):
Here is an interesting thread on the RobGalbraith discussion forum that discusses some of these considerations and is highly rated:
If you want the best results under tungsten illumination, consider using the proper color conversion filter to bring the color of the illumination closer to daylight. Unfortunately, with available light photography you can't afford to use 2 f/stops and the blue cast and dim image in the viewfinder would be unwelcome.
