These links from my Bookmarks should help you out for awhile. I thought I had more but can't find them. Enjoy the read.

Thanks for being so helpful you two. ;']

Thanks for the links (good ones)
For now i have bought two books
I will read these  before i go somewhere else
I think an hardware guizmo will be interesting but i think these are expensif (maybe spider express will be not too $$)

I bought I Spyder v2 the other week cause I was having trouble getting consistant colours and it was driving me crazy.

I've done one calibration and schoo; is still out whether its improved the siuation. You have to be REAL patient work with those devices. I will probably have another go shortly, like any thing I suppose the more time you use it the better your supposed to get :-)

I'm glad those links helped.

Regards
Peter
