This photo was taken from one of the many lookouts on the Blue Ridge Parkway in North Carolina. This road presents many opportunities for great landscape photography, particularly in the fall.
I arrived early to this lookout with the intention of getting some blue hour and sunrise images. However, when I saw the light arriving in this area with early fall colors I thought this would have been the photo of that morning. So, look at the composition and just wait for the moment the light lit the top of the trees.
The haze on the mountain in the background provides a clear idea of why they are called "Blue Ridge Mountains".
