ColtSeaversWhite Balance has always confused me - you've just made it so clear! Making sure my battery is charged up and plan a day of White Balance experiments tomorrow, as I'd been meaning to take photo's of places i'm passing with my dog: and i've been lazy recently, with having the iphone on me, and left my camera behind.
Going to miss your tips but have just bookmarked Everest Trek and will follow your progress with interest. Just in case things are too hectic to post tomorrow - Have fun! Sounds like it will be a once in a lifetime experience :)
