First, what the heck is CHDK??! Basically, it's a "firmware enhancement" for a whole list of Canon PowerShot cameras (supported camera model list here). You follow a process where you copy some files onto your memory card, and instead of your camera booting the "regular" operating system, it boots from the memory card instead.

OK, so what does all THAT mean? Basically, today's digital cameras have operating systems -- software -- that runs many of their features. In fact, software is some times one of the main difference between "lower end" cameras and the higher end Digital SLRs. By loading this software onto your camera, you get access to a whole host of other features. The CHDK in Brief page has a list of those additional features -- the three of most interest to be so far are 1) enabling RAW mode, 2) exposure times as long as 65 seconds and 3) exposure times as little as 1/10,000 of a second. There are all sorts of other scripts that can actual be loaded and run on the camera as well. I'm interested in checking out the intervalometer aka timelapse scripts.

So, I spent perhaps 3 hours on Friday, cursing and swearing after the first 30 minutes, swapping my SD card between my computer and my camera, trying to get this stuff working. Looks like most people that are messing with this are on Windows or Linux, and getting this working on the Mac presents some special challenges.

Here are the steps (and yak shaving) that I had to do to get CHDK running on my Canon S5 IS. This assumes that you won't run screaming from using the Terminal, and are at least going to be OK cut and pasting commands in.

This past weekend I did my first dedicated AdHack session. James and I professed our love for our Canon S5 IS cameras (see my initial write up after I bought it). We ended up with 15 minutes of video, taking turns explaining different features of the camera. The video itself was taken with each of our cameras, and then just roughly spliced together -- we might post process it some more with some subtitles, and maybe even some example photos and/or stills of some of the functions, but it works pretty well for now. Shame on other potential AdHackers that didn't brave the snow to hang out and make social media with us! :P

Oh, and I fiddled with the Brother printer that Monique is reviewing and got the wireless working (although this beast they call PictBridge is still pretty mystifying).
