Of course, while making these refinements I also modified some of my HDR images, including those from my last blog post - such as the Midland Valley Bridge image. So here is the latest (and final) version of that image:
If you're waiting for me to reveal what these settings are....it's not going to happen yet. They're not exactly secret or anything, all adjustment settings within Lightroom, but they are what I identified (through experimentation) to be the most pleasing to me, so in essence they have become my "style". If you spent a few hours in Lightroom and played with the various settings, you would likely find "my settings combination" but you may also find your own style in the process. And to me, this would be much more preferable as it's better to do your own work than it is to copy what someone else is doing.
I can use these settings both on bracketed multi-image HDR sets and also on single (RAW) images to give similar results. They have been tested on both types and give good results, dependent on the original image(s).
