Beautiful animals for sure Steve, and as usual, you have done a great job capturing their images. The busy backgrounds don't really bother me much, as they show the horses and riders in a real-world environment. You might get better overall shots out on rolling pasture, with beautiful mountains for backgrounds, but you would also probably not get many shooting opportunities. :wink:
In checking for Lost Highlights in NC4, many times I didn't miss the right exposure by much, other times they were off by as much as a 1/2 stop. btw, I'm using Fred Miranda's D2X CS Pro Sharpening plugin for PS, and really like it. For web shots, I usually set it to High ISO, Level 1, Low Halo, then check the Save as a Layer option, then dial back the opacity slider to anywhere from 50-80%. For full size shots, it's a much stronger setting.
