HDR

I'm playing around with HDR photography just a bit. It's a digital post-processing technique that uses multiple exposures of the same scene (ideally, tripod mounted identical shots) taken at different exposures. Essentially, for shadows it uses the over-exposed image, for highlights the under-exposed, effectively extending the dynamic range of the camera sensors.

The technique first requires that the shots be aligned precisely - or if not identical, manually lined up. With my little tripod I was able to take some good sequences that align well. Next there are a bunch of different algorithms each with a number of settings that I don't understand yet at all.

For now I just chose a few that look interesting, in full original 6M pixel resolution. Neither looks like the actual scene. I like the sky in the first one especially. The second one looks like it was shot at night in a full moon perhaps.
