9/15/2010: Mousam Marsh HDR Panorama

So, what would happen if you combined HDR with Panorama? This is 12 exposures, 4 sets of 3. I processed each set of 3 exposures in Photomatix for tone-mapped HDR, then the 4 HDRs were stitched in PhotoShop Elements, using its excellent Panorama tool. The pano was then taken into Lightroom for final adjustments (straighten, levels, sharpen, etc). If you look at it large enough (which I recommend anyway as the little image here does it no justice) you will see that the fence posts on the left center are not perfectly aligned (the wind was blowing so hard I had trouble holding the camera still), but, in general, for such a complex process (and no tripod), I am happy with the results, especially for a first experiment. This is a sweep of about 180 degrees, from Great Hill, past the mouth of the Mousam River, and all the way around to the Route 9 bridge…the equivalent of 4 28mm fields of view.

Canon SX20IS at 28mm equivalent field of view. Exposure sets separated by 3EV, auto bracket with the center point adjusted to –2/3rds EV using Exposure Compensation. Processed as detailed above.
