I made the jump from CS2 to CS4.

I am having issues with the color space assignment. I work in sRGB most of the time. When I use proof colors (in CS2) I can match the final output.

In CS4, I do pretty much the same thing, save for web, upload to DPC. But the uploaded image in the browser looks must more contrasty and saturated than the jpg opened in CS4.

I reedit the image in CS2 and the uploaded image looks almost identical to the saved jpg.

Any help is appreciated.

Are you checking "convert to sRGB" option in Save for Web?

I think it is checked by default, but it it already is sRGB, would that switch have any effect?

It may not already BE sRGB: I'm not an expert on this but there's sometimes some confusion where it says it's in one color space but it's actually in another; like you could be editing in Adobe RGB and displaying in sRGB or vice versa. If the output to DPC looks different from what you see on your screen in CS4, and if the "convert to sRGB" actually IS checked in SFW, then there's a good chance that the colorspace CS4 is displaying is not sRGB, regardless of what you think it is. I know people have gotten tangled up in this, but it's never happened to me and I'm not sure of how to check it out, especially since I don't HAVE CS4...

It may have something to do with the "proof colors" option and what it's set at...

I have proof colors set to Monitor.

Seems like it is a lot more tweaky than in CS2.

Thanks for your help Bear. Anyone using CS4 out there?

Are you using GPU acceleration? If so you need to go into the options, enable the check button that allows the GPU to color manage, uncheck it, then check it again...

I think its called a bug.

I just started using CS4 about a month ago, so...FWIW, when I started using SFW in CS4, I checked to see if there were differences in proof colors "Monitor" and "Windows - (no color management)" and there were definitely differences from the original image when I used Monitor. Depending upon the image, I got color changes, for instance in one image, the purple turned to blue, and a kind of "grass green" turned to "olive green" with Monitor, but the color was dead-on with Windows. I had a few images show contrast changes as well, but not huge changes - the tone was just a bit different. I stick with Windows now because it seems more reliable in reproducing the image.

Hope this helps a bit.

It has the ProPhoto RGB colour profile tagged.......if your browser is able to manage colours, then you will see it as bright and vivid colours. If not, then you will see it as dull, desaturated, somewhat muted.

Then, my next recommendation is that once you've finished editing your photo, in whatever colour space you prefer, you Edit-Convert to Profile-sRGB, because that is what non-colour-managed browsers assume, and so what the rest of the www( ie, most DPC voters ) will see.

There really is no difference between CS2, 3 and 4 on this.

Bottom line - use Firefox 3. Ensure colour management is enabled. Convert to sRGB just before saving for web.
