Re: [Digital BW] Time to dive in- Start with a calibrated workflow!

2002-08-30 by Bill Morse

Hi Jerry and Julian-

Jerry, AFAIK, you would only have to profile your monitor to a 2.2
workspace.  In my system, I use Optical to profile my monitor (also a
Mitsubishi  ;^), using Adobe98 as the target profile- with a 2.2 gamma and
D65 color temp.  My default PS workspaces are A-98 for RGB and 2.2 for GS.

I have never seen a convincing argument for or against 1.8 or 2.2- for me
it's primarily one of compatibility- most modern equipment (recent scanners,
digicams, etc.), seem to be set to a 2.2 space by default, so in cases where
no profile is applied, or is unknown, a 2.2 space will result in fewer
"upsets."  On the other hand, when I scan with a older Scitex scanner
(designed for a Mac system), I assume the gamma to be 1.8, and set my
monitor to match until I convert to a 2.2 space in PS.

But what do I know...  I'll wait 'til some helpful soul shows me why I'm
half-baked  ;^)
