Lightroom slideshow export - colour probs

I'm trying to export a slideshow as a pdf slideshow file to use as a demo. However, I'm experiencing colour probs....

When I view the show on my laptop the colours are really washed out.... I'm sure this must be a colour space issue but I can't solve it. I have lightroom set to work in AdobeRGB matched to my camera. When I export from lightroom for web etc I convert to sRGB as part of the export process. My guess is the pics are being exported as Adobe RGB rather than sRGB and hence looking crap! I did try exporting the image files as sRGB files, creating the slideshow using these files then exporting the pdf - but no change.

Have done a bit more digging...

If I use the slideshow module to 'export jpeg slideshow' the jpegs which come out have no colour space tag added to the file. However, exporting via the std export and converting to sRGB on the way tags the files with the sRGB colour space setting.

So the prob seems to be that anything I create via the slideshow module has no colour space attached and therefore looks washed out on another machine - even when the files it was using are sRGB files...

Anyone know a work around. Frustrating because the pdf slider show does just what I need - but not if all the pics look washed out!

Gave it a quick try on my laptop (worst display I have ), and this is indeed what appears to be happening:

The images inside the PDF are sRGB, but there's no profile embedded.
Preview (which is color managed!) and Adobe Reader (not sure if it's color managed) assume that "no profile" means "Monitor Profile" (Safari is equally stupid in that respect)
Really, really silly. What makes it even more silly: If I open the pdf in PSCS4, then *assign* sRGB, and then resave, the .icc profile is embedded, and the image displays correctly.

Do you have PSCS4?
In Bridge CS4 you can also make a pdf, and you can embed a profile there...

Alternatively; try to find some software that let's you assign sRGB to the pdf.

This is stupid programming on Adobe's part. No other word for it really.

Edit: Just filed a bug report on this, since IMO it's a bug, not something to request as a new feature

Thanks for confirming it wasn't just me! And for pointing me towards bridge.

I exported a slideshow as pdf from there and it works fine. No as much flexibility as to the look which lightroom provides but at least it works.....!

Cheers
