I took this image of the Illinois River Valley a couple of evenings ago of the early color change. I am not a landscape photographer so I am looking for help of what I might have done to improve the image. It was a beautiful fall day the contrast between the shade of the trees in the foreground and the river in the distance were nearly 7 stops different. I took 6 images with about a stop between each exposure and merged the images using Photomatix, then may some slight changes in PS. The shooting info was as follows: Nikon D800E, Nikon 24-70mm at 48mm, ISO-100, f/20. ANy help will certainly be welcomed.
