and back was a damage free process, that is, you would end up with the same color co-ordinates when you arrived back from Lab mode.
"RGB>LAB>RGB is damage free, but CMYK>LAB>CMYK is not. The damage isn't all that great, so in many images it pays to come out of CMYK so as to take advantage of LAB's strengths; sharpening, however, is not one of these cases. .... Dan Margulis"
But you sould know that nosense knows much more than Dan Margulies.
i do, as do most people, but that's not the point.
read the thread before you say more stupid stuff.
chris murphy and andrew rodney in that thread pointed out dan margulis' errors, and many, many other people do so in other venues. dan is often wrong.
And your documents to prove hime wrong are:
in the above link. duh. are you that stupid?
there are other references, but that one will suffice.PeterNnospam
It so happens that I often switch between LAB and RGB, and have never see a loss.
just because you can't see a difference doesn't mean there isn't a difference.
there's no visible loss with jpg at its highest setting, so according to you, jpeg is lossless.
idiot.
talking to yourself again. I ask for proof and you call me names. There is an obvious conclusion to be draw.
