Note: Pan uses a process called HDR, short for high dynamic range, which involves merging several images into one to improve contrast and, I’d say, overall coolness. Here’s a good tutorial on it. And here’s a link to Pan’s own site, from which longtime readers of this blog will note I have, er, borrowed before. (With permission.)
