<p>Herma, that simply indicates that Photoshop for some reason was set <strong>not to preserve the embedded profile</strong>, which is not the default. Properly configured you shouldn't have to worry about this.<br>

<br />Ian Lyons has a good article on the subject: <a href="http://www.computer-darkroom.com/ps12_colour/ps12_1.htm">Photoshop CS5 - Color Management</a><br>

Scroll down to Color Management Policies , Fig. 5 and on.</p>

<p>"But after the editing is done, it still has to be exported out of LR into something more usable, such as sRBG."</p>

</blockquote>

<p>What's "usable" depends entirely on where the image is going next. For web use sRGB is perfectly fine, as it is for most mass-printing services, since they often assume sRGB anyway.<br>

However if I was going to pass that image on to someone else for further edits or high quality printing, I would opt for ProPhoto in order to preserve as much of the image's original colour information as possible.</p>

<p>"It took me a while to figure out why colors shifted so much between Lightroom and CS5."</p>

</blockquote>

<p>Since both applications are colour managed, you should <strong>not</strong> see any difference. If you do, that usually indicates a problem.<br>

By the way converting images and bringing them back into LR in sRGB for further edits is not a good idea: you'd want to maintain them in the largest colour space for as long as possible.</p>

<blockquote>

<p>"I will change the color space to sRGB and see if that fixes the problem and let you know."</p>

</blockquote>

<p>If you have been uploading images in a larger colour space (e.g. Adobe RGB), then that is most likely the answer and you should definitely switch to sRGB for web exports.</p>

<p>A lot of sites that offer upload facilities, actually just strip any attached colour profiles <strong>without</strong> performing a proper conversion to sRGB in the process, which would explain the difference in appearance even when viewed in a colour managed browser.</p>
