I love Moab. I haven't got to spend much time photographing, but would like to get in some backpacking/photography there.
How do you achieve the six shot pano's?
I shoot vertically (portrait) at 40mm (80mm full frame equivalent with my m4/3 Oly). You can capture a similar scene with a wide-angle and crop, however the look is much different. Wide-angle lenses push the background way out, while telephotos compress the distance bringing the background closer. My 40mm (80mm) gives a pretty good representation of what the eye sees.
1. Shoot in manual mode (can't have the exposure changing across the image)
2. Make sure your focus point is in the foreground
3. Stop down for higher depth of field
4. Overlap each shot about 25-33% (use a landmark each time)
5. Stay as level/vertical as possible
There are several software options available for stitching. I used Hugin for these two.
