A few more shots.
Nesting Barn Swallow
A long way off but I like the light
I think your post is a Great example of the variation in pop and micrp-contradt that occurs that is directly related to the quantity of available light (EC value) and not just ISO. Notice the diminished appeal of the first shot vs the rest where the first photo had 5 stops or more less light. Just a fact of life of digital sensors. (less dynamic range and color resolution at lower light levels.)
Over in the focus thread it would probably be a good example to keep in mind when they do analysis.
