Thanks. Ive been messing around with a RGB colour map, but so far didnt get any wiser. I guess it takes a lot of time to get the insight. I have seen the flash bundle at Cornucopia, and I would like to buy it actually, but i dont have a credit card... And I dont have any inspiration to create the winning Winter Wonderland Contest picture, where this flash bundle is the price... ;) Ill just have to work hard on my patience then...
