Digital BW, The Print

Hello Mark,

I don't know if this will help your client, but I use a Canon Pro-1 (8
mp) and have it set to BW mode.  So the preview screen and the EVF
both show a BW image.  Because I shoot in RAW mode, while the captured
image looks BW, all the color info is still there, and if I want to I
can put it back in color mode when the RAW conversion is done.  I've
found that I have better control over the Color-to-BW conversion using
Channel Mixer, etc. when I start from the color version, so I usually
do this.  However, if your client wants to avoid the BW conversion,
the RAW file can be converted still in BW mode, and on the Pro-1 the
results are quite good.  

So this gives us the best of both worlds.  We can visualize and shoot
in BW, but have full control at the conversion stage.  I don't know if
other models/brands do this, but I suspect they do since RAW mode is
supposed to preserve all captured data.  I hope this helps.

Regards,
Clayton
