HDR with chdk and Ubuntu

I recently purchased a Canon PowerShot sx40 hs. It didn’t take me long to install chdk, an alternative firmware available on Canon’s PowerShot line. One of the features I was most interested in was bracketing. Bracketing is the technique of taking a number of pictures of the same subject with different settings. Once you have a number of bracketed pictures, you can create HDR images by feeding them into a program such as qtpfsgui.

sudo apt-get install qtpfsgui

… with the universe repository enabled if you’re running Ubuntu.

I realize I’ve thrown out several terms that you may or may not be familiar with. Rather than spending time walking you through each, I’ve provided links to the appropriate documentation. Instead, I’ll use this space to show off a few images I was able to produce.
