Pre-processing to Reduce Distortion Improves HDRs

This is a study about technique and not composition. I could have run this test on anything, but the pink amaryllis flower my wife Rose put in the window (they're blooming in Virginia right now) inspired this shot.

 

Back to the point. Any distortion in the images used to make an HDR will be amplified after the images are merged. This picture is the result of pre-processing to eliminate chromatic aberration, geometric distortion, white balance, and other distortion before merging the images to make the HDR. To fully appreciate the result look at the edges and high contrast parts of the full-sized version.

 

9 shots at 2-stop intervals.
