jaapv Posted June 9, 2009 Share #21 Posted June 9, 2009 Advertisement (gone after registration) Sorry but the statement "non-destructive" turns on a flashing red light for me.When ever I've heard the word it has meant damage. I have my doubts there as well. But the fact remains that you can convert from RGB to LAB and back again at least 25 times (the number at which I stopped testing) with no perceptible change to your file. At any rate Scott Kelby and his gang claim the transition is non-destructive. It is certainly not like aRGB-sRGb or even worse - RGB-CMYK, which will truly harm your files and is irreversible.

I follow you, the LAB color corecting just have a special "look" to it. Does anyone adjust color/white balance by boosting saturation, adjusting for the most even balance and then turn saturations down again? Link to post Share on other sites More sharing options...
