Bill ee, did you do anything besides saturation? I really like how the sky pops with the highlighting and rays.
If you like, DxO's Optics Pro 5.3 will automatically correct for that lens disortion of the straight lines near the edges curving. I use DxO for my RAW conversion and automatic correction for geometric lens and body errors and then use PS for more serious adjusting. The DxO allows lots of adjustments to saturation, contrast, dynamic range, straightening horisons, etc., so most of my images don't go into PS. I find that DxO does a much better job than Canon's software and is much easier to use for these type adjustments than PS.
Getting rid of lens distortion used to be no big thing to me, until I processed my first batch through DxO and saw the before and after. Now I notice it on the images of others and have become an apostle for DxO. Sorry, I'm not meaning to take away from a nice image.
