Digital BW, The Print

Eric,

I'm not arguing that direct grayscaling is the best method.  I am just stating what the 
default is in my CS2.  If you do the check I mentioned it will show you that is exactly the 
case. I  have also read it elsewhere, but I can't find reference to it at this point. You guys 
need to come up with some authentication for your opinion- it sounds to me like you just 
think it is improbable. 

Personally, I choose to use direct grayscale because you can drive yourself crazy seeing 
what tweak works the best using channel mixer.  I have found it much more effective to 
convert to grayscale directly  Image>mode>Grayscale and then work on the image in 
curves.  I find it gives me much more control.  You wouldn't think so, but for me, it does. 
Like anything in Photoshop there are many ways to achieve what you want.

Regards,

Lincoln
