Is this correct sub-site? I may need a site map.
My question concerns black and white conversions of RAW images in Adobe Raw. For me it is guess work as it is difficult to incrementally adjust the sliders with any wisdom. Is there a method to this madness? Do we just adjust until it looks OK? Is the blue channel useful for a specific tonal section. Please advise.

Mark,
If you want to convert in Adobe Camera Raw, you'll go nuts until you upgrade to ACR 4, which is included in CS3. ACR 4 has a tab devoted specifically to grayscale conversion. More flexible and much much more intuitive to use than ACR 3. The difference is so big that I wouldn't even waste any time playing with ACR 3 for a grayscale conversion. Just bring it into PS in color and use channel mixer. In channel mixer just keep your total percent (RGB) close to 100. Keep in mind you can use negative values. Play until it looks pleasing onscreen.

Amadou: Can you define "pleasing on screen"? I can find pleasure in so many directions.
