my ninja reflexes came in handy that one time!
anyway how many of you guys use the AdobeRGB colour space in your Creative Styles selection?
i use it on my a700 and set LR and CS4 both to AdobeRGB as well and when saved to jpeg the colours are consistent. but when uploaded it becomes a little dull (now that i can actually notice the colours).
I know i can counter this by saving with sRGB colourspace but the Save to Web option in CS4 is a little tedious!
has anyone printed the same image saved in AdobeRGB and sRGB and notice a difference?
if there isn't a difference, i wouldn't mind streamlining the camera and my apps to sRGB instead!

The AdobeRGB colourspace is larger than sRGB so the rule is to edit in AdobeRGB at 16-bit depth. For the web convert to 8-bit sRGB. I find this best done in CS3/4 with an action.
For instance I have an action for DCRP posts which ...
Converts to 8-bit
Converts to sRGB profile
Resizes to 800 wide (Scale styles//Constrain//bicubic sharper interpolation)
Saves as a JPEG to my DCRP folder
This takes place in no time at all and is dead simple to set up.

and that maintains your colour on the saved jpeg and after uploaded to the web?

Adobe RGB colour space has a significantly wider colour gamut than sRGB; it was designed (back in 1998) to encompass most of the colours achievable on CMYK color printers. sRGB is considered adequate for most consumer applications and having all devices use the same colour space is convenient in that an image does not need to be converted from one colour space to another before being displayed, however sRGB's limited gamut leaves out many highly saturated colours that can be reproduced by printers or film and is not ideal for high quality applications. That's why the wider gamut Adobe RGB is being built into DSLR's and is favoured by professional users.
So the answer to your question is no; converting to sRGB is a destructive process which chucks away some colour information just like using jpeg compression chucks away your pixels.
Web browsers use sRGB and don't understand AdobeRGB, so unless you post in sRGB the browser will render the colour in unexpected ways.

thanks Peek. seems like the only colour space aware browser is Safari and Firefox has a plug-in to enable it.

Yeh! I don't think there'll be any rush to change the status quo.

I just did what this said but I don't know why.LOL
Enabling Color Management in Firefox version 3
By default, color management is disabled in Firefox 3. To enable it, just enter about:config in the address bar, promise to be careful to the popping window and type “color_management” in the filter. Change gfx.color_management.enabled to true. This means that Firefox will honor the profiles embedded to the images it displays.
The next thing you can do is point gfx.color_management.display_profile to your monitor ICC profile (if you have one available). This way, Firefox will optimize its color rendition for your monitor.
Close and restart Firefox to have your options taken into account. You can check this link to make sure it is properly working – the mountain image at the top should look normal (and not 4 quarters with different weirdo colors) .

I didn't think to say, but if you are not au fait with "Actions" in photoshop, I could send you the one I recorded if it helps. PM me if you want it.

Thanks Peek I was going to ask and got side tracked with changing what ever I just changed in Firefox.LOL
