The slight noise increase caused by altering the channel mixer is measurebating and doesn't even show up on the print. You get much greater control by converting to b&w post production. The increase in noise is caused from the fact that you are amplifying each channels noise when you change the RGB relationships in the channel mixer. The more drastic the change, the more noise you will see.Kent Frost said:I beg to differ unless you're simply converting to grayscale. When I refer to converting to BW, I'm referring to using the channel mixer to achieve the effect of having used colored filters. If you've done it like that, then you should be able to see the loss in quality when viewing the image at actual pixels because of the way you'd be boosting or lowering the three channels that make up your total clarity. In the Rebel XT and the 20D, you can shoot in grayscale mode in the camera with the use of all 3 color sensors, giving you same effect when you use actual colored filters, and you'll have the use of total clarity.
