Whoa! Thanks Baldy! Sorry for the delayed response, I was out riding for a few weeks. The pano was shot with a Pentax K-5 and a Pentax DA*16-50 f2.8 lens at ISO 100, f 8.0, 16mm and from an unstable lightweight tripod. The shot was 4 wide and 5 RAW exposures each. I merged each set of brackets to HDR in Photomatix Pro then stitched them with Microsoft ICE. I used Lightroom 3 to process the images before HDR and for the final processing of the finished stitch. As to your last question, I'm not sure which photo you are specifically referring to. If you want, point it out of the Slideshow Gallery here, I can tell you more about it. I don't have much from Zion posted, as I've never been very successful shooting there, so it's probably from the Grand Canyon or somewhere in Southern Utah. Thanks for visiting my homepage and for the compliments. I shot a few more pano series recently and hope to add more to this great thread soon.
