With regards to HDR, I have been a proponent of Photostudio 2 by Unified Color for a few months. They have just released a new version called "HDR Expose". The few things I didn't like about Photostudio, they have completely revamped and fixed with the new version. I played with the program a little bit and ordered my license. I think the results are more realistic, however, you can spice up the saturation if that floats your boat...It all works in 32 bit and has a Lightroom and Photoshop plug-in. Below is the link to the review done by Terry Reinhert photography. It's worth a look.....Big Jim
