Which do you use? What are the pros and cons of each?
I have always used sRGB no reason, just never changed it.
Which is better for CS5 6-bit and Lightroom 3.41 64-bit?
Thanks in Advance

I prefer Adobe RGB for serious editing and printing. sRGB is what I use for the web. Here's a decent comparison of the two color spaces.

Paul- sRGB has a smaller colour gamut than Adobe RGB so I've always understood that it's better to edit in the bigger colour space. However, I strongly suspect that in the double-blind experiment with prints no one could reliably tell the difference!

I maintain the Pro Photo space converting to Adode RGB for (most) printing and sRGB for web.

OK Don, you have now thrown in Pro photo which has a bigger gamut again than Adobe RGB and sRGB. It may indeed prove itself in a double-blind experiment against Adobe RGB and sRGB but again I frankly doubt it. These urban myths tend to be established out of faith in the theoretical outcomes, but the properly controlled experiments to prove they work (or not) have rarely if ever been done. I use Adobe RGB through most of the post-processing phase because I believe that theoretically it must work better than sRGB. I haven't got the foggiest idea if it actually does so.

John,
I agree in real world viewing it may be very difficult even for a trained eye to see any variation in color when comparing Pro and Adobe RGB. I maintain Pro Photo as my working space so that I can maitain as much image integrity as possible as long as possible. Hopefully, when printers and monitors catch up I will not have to redo my working images.
Warm Regards,
Chas
Don,
Color shifts from Adobe RGB to sRGB should be very minimal. We had a thread about this earlier. If you see significant color shifts with such a conversion, your system may not be properly color managed. See:

Good discussion. I have assigned Pro to my Light Room conversions, and save the LR edits as Pro Photo. Then in PS I convert to my Adobe RGB color space for final processing for print. Of course for web I convert yet again to sRGB.
Roger,
Agreed, but LAB involves converting from Pro Photo or Color Match and then from LAB back to Adobe or sRGB for use .... as no converter will do so from RAW. Yet another step in the conversion process. And, are these back and forth conversions in LAB really non-destructive?

Any conversion with integer data involves some round-off, so none are technically non-destructive. But with 16 bits/channel (or more), I would bet you could never see the difference, and it would be tough to measure any real destruction.
The other question, does any digital camera have a larger gamut than Adobe RGB? For example, the 1D mark IV seems to have a color gamut much smaller than LAB:

(not sure where the prophoto gamut boundaries are on this plot.

Hey Don if I had one of your Color shifts I'd try to correct it too!!![]()
