I was on vacation in Romania a while back, and they have some beautiful old-growth trees there. I was walking up a trail and came upon a huge old tree that was just perfect, and the sun was to the left behind the tree shining through the leaves making them glow an emerald green. I have never been able to sucessfully capture "glowing" trees, and this time was no different. They always come out looking dull. Anyone have pointers on how to capture that glow?
