Preparing scans for web: RGB mode
I have recently got CS2 and am trying to get to grips with it.
My question about preparing images for viewing on-line, including this forum is:
I understand that it is best to convert to sRGB at some stage, either through the profile or automatically through 'save for web' or via 'Image Ready'.
What I don't understand is this: I've just recently (yesterday) re-calibrated my monitor, via systems preferences, I have an emac. But when I look at the proof set-up, through 'View' and click "RGB Mac" the image lightens significantly. I know that macs display images lighter than PC's but I don't understand why I notice such a change when I myself have a mac.....There is also quite a (different) shift when changing to sRGB - so which proofing set up is it best to go for, as the final intention is to change to sRGB?
Bearing in mind it is best to make all alterations before changing final RGB profile, it seems it's important to understand how it will finally look when you are making those changes.
I'm trying to get to grips with at least knowing how my image should or could look on-line, as far as I'm concerned, even if obviously impossible to take into account everyones different monitors.
Thanks for any advice!

In your situation ignore Proof Setup in CS2, it's used for estimating how a soft-proof will look on paper - you're dealing with monitors.
Most colour management people will tell you to calibrate your monitor to a gamma of 2.2 - even for Macs. It's explained more in depth in the book Color Management from Real World http://www.colorremedies.com/realworldcolor/index.html.
The method I have been using is to convert all files to sRGB from my Working Space of Adobe RGB (1998) and use Save for Web to optimise them. I'm not an expert in this field but I work closely with someone who is and this has worked well for me. His other advice for the Color Settings in CS2 is to set them as follows:
Working RGB: Adobe RBG 1998
CMYK: US Sheetfed Coated v2
Gray: Gray Gamma 2.2
Dot Gain: 20%
