This is a slightly modified photo to enhance the composition. There was a cluster of greenish-brown leave at the bottom center of the image. They weren't helping things; I made them go away.
Are there ethical issues with doctoring a photo like this for artistic reasons? It's not photojournalism, it's not part of any smear campaign.... Personally, I am okay with this sort of manipulation. I don't do too much creative enhancement to my photos, but quite often this is because it is too hard to do anything more than erase a leaf from a solid blue background. In this case removing the leaves helps make the photo more about color and focus and less about the tree itself.
