Colour Space exporting

It's hardly a sexy subject - and nothing to do with actual photography - but it's an important part of showcasing photography: which colour space should I use when exporting photos from Lightroom?

Ladybird II, originally uploaded by David Romanis.

Annoyingly, I've discovered that I've been using the 'wrong' colour space (or "color space" as Lightroom calls it) - AdobeRGB strips the photo of some of its vibrance and saturation and the picture becomes a little duller.

I performed a simple experiment earlier on, exporting the original RAW file from Canon's Digital Photo Professional (DPP) software to create a JPG, dropping it into Lightroom, then after a few tweaks, exporting using different colour spaces.

In order of closeness to the original shot, from closest to furthest away, sRGB was best, then AdobeRGB, the ProPhoto RGB.

sRGB is pretty much the same as the shot I opened in DPP; the AdobeRGB shot desaturates slightly; the ProPhoto RGB export might as well be black and white. Almost.

So, note to self: export from Lightroom using sRGB. Glad I found that out after having only exported 16,000 pictures...
