As I’ve already alluded to in a previous post, I’ve been using the CHDK firmware supplement with my Canon PowerShot A550, which on it’s own is an outstanding camera, alhamdulillaah. This firmware add-on, though, really takes the cake!
One of the features made possible by CHDK is the ability to run scripts which take the enabled features of your camera and do interesting things with them. One such script enables one to take a sequence of images of a fixed interval over a period of time – i.e., time-lapse photography! So, over the past two days, I’ve gone-ahead and played with this feature a bit by just collecting images from my office window while I diligently “worked”.
Through the script menu, I was able to setup the time-lapse to take one photo every second. As my office is on the 4th floor of large cubic structure in the suburbs of Columbus, Ohio, I had a nice view that combined parking lot-and-street activity with some nice cloud shows. That both days were signficantly overcast actually proved to make the videos more interesting – so much so that the last image sequence was pointed more towards the sky to capture the natural splendor up above.
Note: All videos are in free and open source Ogg Theora format. If you do not have a player that supports this already installed, then I recommend the VLC free and open source player. Most users of a GNU/Linux or other *nix-based systems will probably not need anything special to player, so this note is mostly for Windows users.

This was my first image sequence out of my office window. The white balance is really off, unfortunately, because I didn’t attempt to adjust it at all. Subsequently, the entire image sequence has a color hue due to the tinting of the office building’s windows.
My second image sequence came out a little better with regards to color, because I set the white balance to “overcast”. This is still not as accurate as it could be, however.
The third image sequence is the longest, and first one from the second day. This is a sequence of 600 images in total! I manually adjusted the white balance for this and the next sequence, and as such, the color appear much more natural & realistic in these two sequences.
The last & final image sequence for this batch was really just something I did without giving it much thought. Amazingly enough, it turned-out to be the most interesting until the end when it gets cut off (due to lack of space on my SD card) – the direction of the clouds began to change! This sequence in particular encourages me to try to stake-out a day with excellent cloud activity and just setup the camera to capture as long a sequence as is sane.
I hope you’ve enjoyed this post and these clips as much as I did making & manipulating them. I’ll make another post explaining how I captured the images & converted them into videos. Feel free to post comments and/or questions should you have any.
