Digital BW, The Print

Thanks to everyone who provided advice on matching the monitor and
print.  Two adjustments got me reasonably close.  First, I used the
advanced rather than the easy mode for the Xrite oneeye2 software and
second, I reduced the luminance of the monitor substantially.  While
the controls on my Dell 24" monitor would not allow me reduce the
brightness sufficiently to get to the target luminance of 90 cd/m(2),
I got most of the way there. I still need a slight brightness
adjustment curve to align the print and monitor, but that is easy
enough. Furthermore, since I use monitor's DVI connection to my Mac
for photography and the VGA connection to a PC for work, the dimmer
setting does not pose a problem.

Just curious why you used that target, I have all my monitors set for  
120 cd/m.

Display brightness (technically "white luminance") needs to be set to relate to your ambient light and proofing light. 90 cd/m would be good for near darkness; like old CRT workspaces. 120 is good for dim but not dark conditions, more common today (mostly because LCDs make it possible).

I am dim (pun intended).

Hi Mark.  Here's my perspective on monitor luminance.

I use 90 cd/m2 regularly for white luminance, even on my LCD.  I
generally start with my normal viewing environment (where the picture
is hung) and work backwards.  Most display environments (homes,
offices, etc) are fairly dim, and 90 has always worked well for me.  

The next step backwards is the viewing light or booth, which I try to
keep at a fairly low level, so that it comes reasonably close to
approximating the final viewing environment.  Stepping backwards, that
translates into a lower monitor luminance.  They are all equal
partners in the chain.

If I were viewing my final prints in a very bright environment, or
under dedicated spotlights, then I would consider a higher white
luminance.  They are all parts of a "complete system".  But, I have
found that using high white luminance often translates to dark, muddy
prints, unless of course, you proof AND display them under bright
light conditions.  Usually, people who complain their prints are too
dark solve the problem quickly and easily by lowering their monitor
luminance (assuming they are printing with accurate custom profiles).

It makes no sense to me to look at a print in a very bright viewing
booth (except to get a look at details), then display the print in a
relatively dim environment.  The print will just end up looking dark &
muddy, with loss of shadow detail and separation.  

I advise people to use whatever works for their "system", but if they
are complaining about dark looking prints, try a lower luminance and
see if that works for them.  In my experience, more often than not, it
does.  

Regards, Lou

Mark,

Basically advice from various members of this group.  It does seem to
work. I have know way of knowing how close I got to the target.

That should be I have no way of knowing.
