Edits were done in iPhoto.
(1) Increased the black level to +10%. This has the effect of adding richness to the hues and strengthening the contrast between the sunlit and shadowy areas.
(2) Sharpened the image (+40%). Clarity in the original was very good. It seemed possible to improve it slightly by further sharpening.
(3) I had to reduce the image size slightly to fit within the TE limits.
