Anybody here using Mac OS X?

If so, please excuse my beginner's ignorance... In general, I'm fairly confused 
about color management as relates to workflow. I'm trying to use Jeff 
Randall's workflow (1160; FS-N) on a Powerbook G4 (with the crappy built-in 
Powerbook monitor ... it'll have to do for now) with Mac OS X 10.1.5.

What I'm wondering is what settings I should have in the ColorSync system 
preferences panel, where I'm supposed to set the gamma (Monitors system 
panel or Photoshop, or both?), which profile to choose in the Displays system 
prefs and whether I should choose adjust/calibrate the display after choosing 
a standard display profile like Adobe RGB (assuming that's the correct one).

Other problems/questions: I use a Polaroid Sprintscan 4000 with Vuescan... 
which color space should I be scanning in (I'm mostly scanning B&W negs, by 
the way)? Should everything be set to the same color space?

What about printing... the ColorSync system panel has output color space 
options, the Epson printer driver has color space options, Photoshop has 
color space options... I'm thoroughly flummoxed.

Any help from fellow OS X users would be most gratefully received.

Welcome to OS X! I'm in Jaguar now so I think Apple improved ColorSync from 
10.1.5.

To set System Monitor Profiles - Go to the Displays in the System Preferences. Go 
to the Color tab and click on the Calibrate button make your own monitor profile. 
You should be using 2.2 Gama. Start of with the default monitor space - should 
be named something like Apple Powerbook Profile....then Calibrate. 

Adobe RGB is not a monitor space - it's an image space - so don't choose it for a 
monitor.

Use Abobe RGB for your color space in Photoshop and in your scanner software if 
need be. 

Also go to:

This website has a wealth of info. Go to the Feature Articles pulldown menu and 
you will see articles related to Color Management, Photoshop 7, OS X and Printing 
to an Epson printer.

Hi Peter,

There are quite a lot of options in many different places but by and large
you want the generic choice.   I use the Roark workflow not the Randall one
but I think for the most part they work alike -- just different ink sets and
different curves.  

Here's what I use:
System Preferences>Colorsync:   all generic profiles (RGB,CMYK,Gray)

Photoshop > Color Settings:    Web defaults or possibly use Adobe RGB
all color management policies OFF.   (Gray should be Gamma 2.2)

All my scans and files are "untagged".

When printing -- the Print Dialog should have under Color Management
Source "Untagged RGB" , Print "Same as Source"

(you might also read the Roark flow for any other questions)

--------------
I think about the most helpful thing is to work with the 21stepNew.jpg
file found under Files>ImageProcessing.    Looking at it on the screen
you should see separation for every step and printing it out you should
also get a similar result.
