9/23/2010: HDR Marsh Pool Panorama

This is another experiment in HDR Panorama…and this time I had a tripod with me! It does make it easier, and, despite the lack of a true panoramic head, I am pleased with the results. I especially like the rendering of the sun on the pines at either side, which would have been quite impossible without the HDR treatment.

Canon SX20IS at 28mm equivalent. 9 exposures in bracketed sets of 3. All at ISO 80 and Programmed Auto. Bracketed 2 stops, with the center exposure moved down 2/3EV via exposure compensation.

Each set of 3 was blended in Photomatix, using tone mapping. In this case the smoothing had to be adjusted to a minimize the light sky band along the tree line. The 3 HDRs were then taken in to PhotoShop Elements 7’s Panorama engine, where they were automatically combined. I also a darken brush along the tree line to smooth the sky line a bit more. Finally, the image was saved as a PhotoShop file and taken into Lightroom, where some Recovery was applied for the sky, added Clarity and just a bit of Vibrance, and the Sharpen narrow edges preset. I also used the selective luminance tool to intensify the little bit of fall color in the tree line and bushes on the left. This is a LOT more processing than I generally apply to any image, but perhaps, if you view the Pano at larger sizes on my SmugMug site it was worth it (click the image above, or here, and use the size controls at the top of the window…though it should auto size to your monitor).
