I have a Nikon D40 with the 18-55mm Nikon Lens. I just got it yesterday and I already ran into a challenge. I'm trying to take pictures outdoors. It's very sunny and bright. I'm shooting in A. I want to see the beautiful blue skies in my photos, all I get is a bright white glow. help! what should my white balance be? exposure? iso? f? Thanks separate question. How come when I change my metering settings, I am unable to take any pictures? Thanks in advance!
