Yesterday it was mighty damp in New Hampshire--enough rain to raise
the level of the lake about 4 inches (10cm). The evening reward was a
spectacular double rainbow. I did my best to shoot it, but had only
grabbed my camera with the 16-45, and had left behind my bag with the
10-17 in it; so I couldn't get the whole thing in one shot.

Now, the question: the sky is much darker outside the rainbow than
inside it, but that wasn't apparent to the naked eye. Also, the
diagonal dark streaks weren't apparent. Can anyone explain these
artifacts?
Cheers,
Rick
The sky is lighter inside of of the rainbow.

The dark/light streaks appear to be reflected crepuscular rays.
