The first one is desaturating because the embedded colour profile is AdobeRGB. You need to convert the colour profile to sRGB before uploading it.

The other one has been converted to sRGB.

Maybe the site is stripping colour space. I Know some sites will strip it IF the image needs to be resized so perhaps PS is doing the same. Maybe try uploading the image to PS again but this time size it within the recommended bounds.


Russ I resize all my web images 720 longest edge cause thats what facebook used to accept as the largest before resizing.

PS is 760 so it wont resize

Actually have just checked this and the exported image says unclaibrated

it started off as sRGB

I will have to see what CS5 is doing once I save the image to JPEG from the .PSD

thanks guys

The embedded profile IS AdobeRGB and that's DEFINITELY what's causing the desat. NOTHING to do with Purestorm, image resizing or profile stripping, EVERYTHING to do with how various browsers that aren't colour managed render images that don't have an sRGB colour profile.

If you configure your Photoshop colour management policies as per this link you'll get a much clearer view of what's going on:

Just remember to convert (edit/convert profile) from your working AdobeRGB(1998 ) colour profile to sRGB before outputting any jpgs for display on the web. Or just include this step in an action that outputs jpgs.

Or, if you wanted, you could just set sRGB as your working profile and let Photoshop convert the colour profile (if it needs to) when it opens the image for editing. That way you won't need to convert when you output your jpg. That's fine if all you ever do is display your images on the web, but if you print them you're probably better off working (and archiving) in AdobeRGB.

I have checked the exported image and not the image that is uploaded to here ... the images says it is defo uncalibrated..

so whether uncalibrated is AdobeRGB I don't know 

I have never had this problem before .... but now you mention browsers I recently changed from using firefox to chrome 

so maybe its like you say the way chrome reads the colours.

thanks for sheding some like

Take a look here and you'll see that Chrome isn't colour managed and also how marked the difference can be if the image's colour profile isn't sRGB:

It would be great if everyone used colour managed browsers but the majority of people don't.

Currently the only way to ensure that everyone sees your image the way you intended it is to convert it to sRGB.
