ive tried for so long to understand this and i just cant. I have a spyder 2 callabrator for my LaCie 19" screen, but it never seems to work 100% correctly, my prints come back form the lab looking dull or colour casted...and i just cent get my head around it.

Does anyone have a website or a book they can reccomend that can teach me the basics without making my brain hurt too much??
