If you follow my work at all, this may look familiar. As I'm wont to do, I revisited this with new tools and techniques. Starting from the original RAW file I gave this the HDR treatment. Thus you will see greater range and contrast across the entire photo. This is particularly noticeable on the back of the egret's left wing.
I also chose a different crop in order to get rid of the little bit of uninteresting sky that I found slightly distracting as well as a more open view. What you see above is the photo formatted for a desktop background. The print looks a little different and can be found in my Imagekind storefront.
If you would like the 2560x1600 image for your own desktop, please feel free to grab it here.
