Originally posted by Wheatfield I'm kinda old school. I still convert via adjustment layers. I haven't found the one button conversions give me what I want, so I end up fiddling more after that than I do with either the Channel Mixer or Black & White adjustment layer.
Anyway, if your screen isn't calibrated, you really can't trust it to give an accurate assessment of the final print, be it B&W or colour.
i dont know what program you use,
but with adobe lightroom, you hit the b/w button and all the tones go into a grayscale, ie, no more colour,
regardless of your monitor calibration.
but wait folks! thats not all
you then can still adjust each of the 8 colours individual grayscale range
and you can still add exposure, contrast, brightness and all that other junk
you have your entire histogram that you can screw around with.
these things matter more with calibration, but at the same time you can trust the histogram to avoid blowout.
it is your choice to under use the tools in front of you, however this bares no impact on their actual effectiveness.
