Dan Margulis and PS elements...

[Niels Rasmussen]

Hello everyone and a belated happy new year to you all. I've read quite a bit about Dan Margulis' book on the LAB colour space in this (and other) forum. I'm making an assumption that to get the best from his book, one would need the full version of Photoshop (CS4, CS5 etc). Is my assumption correct? I currently only use Elements 7 which, for 99.9999% of my pictures, works just fine especially with my beloved CM plug-in. How much in the book can be used with Elements? Many thanks, Niels rasmussen
