One of my favorite HDR nature images is one I took late last fall (early winter) of a tree surrounded by frosty blue-green grass. I have gone by that tree a couple times since. Finally I went by a couple weeks ago while the trees were blooming. The top blog image is a new HDR of that tree with spring colors all around. The second image is the original image shot in the fall. I find that I really like both of these images. As I noted before, good subjects are worth revisiting many times.
