Hummm, two different answers to the same question. This probably happened because I did not ask the question properly or gave incomplete
information.
What I’m doing is the following:
I’m scanning 35mm color film using vuescan software. This program lets me save the image as a TIFF file. I then go into PS and load the Tiff file. This is when I get the three choices mentioned
1) Leave as is (don’t color manage)
2) Assign working RGB: Adobe RGB (1998)
3) Assign profile: (A pull-down of many profiles appears here.)
[] and then convert document to working RGB
I just tried it all three way.
Options (1) and (2) both resulted in an image on the screen that was way
too
red.
Option (3) resulted in good looking colors when I assigned the profile for the CRT that I’m using to view the photo. I created the above "CRT"
profile
using Monaco. I was a bit confused. I thought that maybe I should use
the
scanner profile from which the file was created. It looks like you choose the profile for where the image is going to.
Thank you both for the help.

In Vuescan, simply set it up to save the Tiff in AdobeRGB98, and make sure you have the correct monitor profile selected for viewing purposes *within* Vuescan. Thus, you won’t end up with a warning dialogue and everything will look the same in PS, assuming that you are using the same monitor profile. Your set-up in which you [apparently] have two separate monitors *and* profiles can be problematic – but more on that later.
The bottom line is you’re confusing your monitor profile for a "working color space." The reason you see this warning dialogue is because you have set up your Color Settings to do so: this is a *good* idea. If the file you’re bringing in doesn’t have a profile embedded in it, this is the warning you see; otoh, if it comes in embedded with a profile that is different from your working space, it will give you the option to leave it alone, convert it, or re-tag it with another profile.
My hunch is the source of this file is either a scanner or digi-cam, no? If you have a profile for the device, the *best* thing to do is to tag it with the profile, and then convert it to the RGB working color space of your choice. If you do not have a profile for the device that captured the image (as will likely be the case with Vuescan), the next best thing to do is to simply *convert* to that same RGB working color
space (usually AdobeRGB98 or sRGB, depending on how you set your Color Settings). Or, as I said, simply assign that colorspace in Vuescan and be done with it.
Either way, the purpose of this whole exercise is to end up in a neutral color space [i.e., grey balanced] with as little change to the appearance of the image as possible. If you use accurate profiles all the way through the work flow (input device>monitor>output device), and use a grey-balanced working color space, you will end up with images that require very few adjustments, *other than your creative edits.* In a nutshell, this is what color management is all about: WYIP is WYS is WYG.
Regarding your monitors, you must be using separate video cards for each otherwise you’d only have one profile that can be applied at any one time. What most folks do is to set up all the tools on the one that is either not profiled or is inactive, and assign the working canvas (the image itself) to the profiled monitor that PS is currently using. Check to see which monitor profile PS is using by going to Color Settings, Working Spaces RGB, then look at Monitor RGB – it’ll name the profile there that is currently active in PS. And, if Vuescan uses one monitor profile and PS uses another, you will be totally lost..so, make dead positive certain you have the same monitor profile (matched to the *correct* monitor) used all the way through your workflow.
Oh, and do yourself a big favor and buy a comprehensive Photoshop book. "Real World Photoshop" is a good one, but there are plenty of others as well.
