I had a few minutes before work this morning to try out HDRSoft's Photomagix software. The program takes digital photos taken at different exposures and combines them into one image, a process called high dynamic range imaging, or HDRi.
For my first attempt, I used three photos of the park near my house that were only 1 EV apart, so the result may fail to awe you:
Here's one of the three originals from Monday evening, at the "correct" exposure:
The HDR image looks better, but not that much better. In the next couple of days I'll experiment some more, now that I have a better idea what I'm looking for and how to shoot it.
