Photoshop does not convert via 'save for web'
For the most part I found this an interesting and accurate article. However, one of the changes to CS3 I've been begging for is the autonatic conversion of any working space to sRGB when "saving for web".
Anyone can try the following: I opened an AdobeRGB image and immediately saved it via "save for web". I then opened this 'converted' jpeg and it appeared desaturated next to the original. Since the new file was not tagged with any color space, I opened the "assign color space" dialog (with preview enabled) and tried sRGB and AdobeRGB. AdobeRGB was the color space that matched the original, so I can only assume no color space conversion took place during "save for web" (as your article implies).
BTW ... another peev of mine is that "save for web" also strips the metadata. I can understand this when one would like to make the file a small a possible. However, sometimes you want the copyright and other info maintained, and one wishes there was a preference somewhere. As a result I never use "save for web", rather I understand what I need to do (and want) and use "save as" instead.

Excellent, helpful article
This article was a pleasure to read and I learned alot in a short period of time! Good job!
Thanks for excellent tip
This was certainly the easiest to understand explanation of Colour Space in Photoshop I have ever read. And I really appreciated the tip about setting Document Size to show in the status bar. I, too, was constantly checking Image -> Image Size, but no more. Thank you.
helpful, but did not work completely
I thought this article was very informative and helpful. However, after implementing everything suggested, the originally defined problem is not fixed comletely. At least not on the Mac. I created a brand new image with the sRGB IEC61966-2.1 profile. If use save for web - the JPG looks dramatically different than if save the JPG with the sRGB profile - at least in preview and Safari. So in Safari is is displaying an JPEG with the sRGB IEC61966-2.1 profile differently than a JPG with no profile. In Firefox they look the same.
I also exported PNGs. One with the "save as" commad and one with the "save for web". The interesting thing is the the save for web PNG I made is different even in Firefox from the way the other images look. So the save for web PNG looks different than the save for web JPG, or the profile JPG, or the PNG made by using Photoshops save as command.
The BIG disappointment is that the way Adobe displays the sRGB image in Photoshop is by default dramatically different than what the save for web version looks like in Safari and in Firefox. This is also true for either the Macintosh RGB or the Windows RGB Proof mode. However, if I switch to the Monitor RGB then I can see a pretty close approximation of the how the final exported save for web graphic will look on this same computer.
Where my NEW frustration is coming in over this is the crazyness that Adobe is now potentially adding to the mix with Flash. It seems Flash 8 may be supporting color profiles which will make it easy to have graphics end up not matching when they are embeded in Flash vs. being displayed by the browser. I really don't know how big of an issue this will be, and I am not 100% sure it is true yet. But if it is, this may be good material for another article.
