Why must I manually convert to sRGB?

I noticed recently that when I save for web (CS3) it is changing the color of my pictures. I noticed that CS3 has the option to convert to sRGB when you save for web.

I have "Proof colors" checked, working space is sRGB, and camera is set to sRGB. So now to avoid changing the color when I save for web, I have to manually convert it before I do my editing. Since everything appears to be setup correctly, why do I need to do the manual conversion?

The only change I've done is calibrate my monitor with the Huey Pantone Pro (big difference!) and Proof Colors makes a big difference. Previously it made little difference whether Proof Colors was checked or not. Perhaps all along I should have been manually converting to sRGB?

Thanks!

Where do you find sRGB in cs3? Is it the same as "windows RGB"?

I'm at work now so am going from memory...

I believe under the Edit menu is where you setup your working space. Windows RGB is under Proof Setup, but I don't remember which menu, but I think it's under View.

Proof colors shows you what it could look like if you converted to that color space. It doesn't actually change the space. If your image is sRGB and your working space is sRGB, turning on soft proofing set to sRGB shouldn't produce shifting. There also should be no major shift regardless of having convert to sRGB checked in the SFW optimize menu.

That makes sense, but there was still the shift. What I still don't understand is why I can't bring the sRGB image into CS3, with a working space of sRGB, and then still have to convert to sRGB. Does CS3 change the image during conversion?

Your settings must be off because if you bring in a sRGB image into a sRGB working space and then save for web there shouldn't be much difference (there will be some minor differences because of JPG compression) regardless if you select the convert to sRGB option or not.

You said there's a big difference when you have soft proofing on. In this case that indicates a problem. When you get home you should post your color settings.

I just read that when you convert from raw there's a setting for colorspace. I'm thinking that it's set wrong - I'll report back later. Thanks.

That's what I was gonna ask; are you converting from RAW? If so, you need to specify colorspace in that conversion or it will default to (I think) Adobe RGB...
