Help with Photoshop Modes (RBG, CMYK, LAB)

jamesl

Hi All,

I was wondering if someone could explain, or point me to some good tutorials explaining the methodology behind working in the different modes in Photoshop. Currently, I do all of my work in RGB mode, but I'm wondering if I should starting diving deeper into the other modes in my processing?

Any advice is very appreciated!

Every image has 10 channels - R, G, B L,a,b, and C, M,Y, K

Understanding the different channels content, can be useful in editing images.

An extensive discussion of LAB, based on Margulis' book " LAB - The Canyon Conundrum" begins here - http://www.dgrin.com/showthread.php?t=18203&highlight=Lab+thread+RUTT

A discussion of CMYK is contained in the discussion of Margulis's "Professional Photoshop"here - http://www.dgrin.com/showthread.php?t=48066&highlight=Professional+Photoshop+rutt

Reading these two threads and the accompanying book will keep you busy for a while These were not light reading for me.

I am moving this discussion to Finishing School, since it is really about post processing, rather than shooting technique.
