Hi. I'm going to the Morton Arboretum park tomorrow (http://www.mortonarb.org/main.taf?p=0) to shoot some landscape. I have read a lot about landscaping but do you have some pointers from practical point of view? This is my first time shooting landscape. Should I use automatic WB or not? I'll be shooting using Nikon 18 - 50mm with D80. Thanks for your help. Marek.
