Digital BW, The Print

Hi,
I'm wondering why I ever (partially) forsook my first love of BW and started doing colour as well ...

This problem relates also to toned BW prints, so I raise it here.

I've just printed a colour mural - one that I've done five or six times in the last year and *never* been satisfied with - and printed it, after evaluating the tones under a full-spectrum fluorescent light and outside on a partially cloudy day, calibrating the clouds against the ones I was looking at in the sky.

Well, it looked perfect outside. The problem is that prints are normally viewed under incandescent lighting ... which makes the clouds marginally mauve when I view it inside, with the lights on.

So I may finally admit defeat and end up doing it in BW with QTR ...

The question is, should one evaluate hue under a full spectrum light or daylight, when in reality it's going to be viewed under normal household illumination?

thanks,
Richard

Richard ­ if you have the luxury of knowing ahead of time the lighting under
which the mural will be viewed, why not correct it under that light source?
That way you will have the satisfaction of knowing that it will appear,
installed, as you envisioned it.

If the clouds in the sky don't match your prints, maybe you need to move ; )


 

If the clouds alone are the problem, remove or greatly diminish the color
from the clouds.  There was an extensive discussion about light sources,
color temp, etc.  some time back. I view prints under several conditions and
weight the results toward the tungsten/daylight environment that most will
be seen under. And in either case, color or B&W, the exact hue of your
clouds will not for most viewer determine whether it has merit to be viewed,
but rather the whole context of the image on the wall.

The 2100 mixes all its light grays from Light Cyan, Light Magenta, and 
Yellow, and yes, they can show pink or green edges as you change light sources...

But even a dead neutral printed with color inks will change with light 
source. An Epson 2400 would print these same tones with light gray ink as the main 
component, and the the shifts would be eliminated, without "killing" the tones 
of the clouds...
