HDR

A few weeks ago, I started experimenting with HDR (high dynamic range) images, using QtPFSGUI. They were a bit of a pain to create at the time, because I had to manually adjust the exposure for each shot. Since I started to use CHDK on my camera, I was able to do some bracketing, which made incrementing between exposures or f-stops significantly easier. I spent a little time this afternoon in the backyard experimenting some more. While most of the groups of shots turned out ok, one group really came out nicely. Here's the mid-exposure shot from the group:

Here's the final result after compositing the HDR (best viewed large):

Now that I've got the basic technique figured out, I've got a few ideas on how to experiment further and hopefully produce some even more interesting HDR images.
