JPG from Lightroom - colour is cack

[Coolhand]

I've just spent a while PPing some shots to upload onto photobox and I had them looking splendid. I exported from Lightroom as JPG, at 100% quality using sRGB colourspace (LR and PS are set to use ProPhoto) and the flesh tones have gone horribly wrong, they look like they have a strong magenta cast.

Is this just a result of switching to a narrower colourspace? Or am I missing a trick?

Yes. Make sure you monitor is caliberated to sRGB and stick to that.

Or ensure if you work in ProPhoto your monitor is calibrated to that. There is little point in Pp'ing in Prophoto if your output device is calibrated to sRGB and vice versa - you can put colours out of gamut.

Don't mix colourspaces!

You should be able to get the sRGB output very close with the correct conversion though (perceptual encoding works well)

This issue comes up in various forms wherever folks dick around with colourspaces. Should be a sticky!

Keep it Simple - if you don't understand colourspaces, stick to sRGB end-to-end, its what most of the world uses from printers to monitors.

PS - "You" is a generic "you", not you in particular!

Nice one, thanks for that!

I think the main problem with this is that Lightroom uses prophoto by default rather than sRGB.

I had exactly the same problem when I used LR

I know - there is some logic to it in theory, but it causes no end of problems (as this thread - and numerous other "why do my prints / jpgs look crap?" - threads tends to show)

Its 99.9% colourspace related.

I think one needs a VERY good reason to stray outside sRGB unless you have output needs that requires something else. If you do need to work outside sRGB, then the monitor must be profiled for that colourspace, with an appropriate sRGB conversion algorithm so the rest of the world sees it how you see it.
