Aquarium Timelapse


Aquariums can be stunning. 

Some time ago (Sept. 2010), we had this aquarium at work.
I thought it was pretty static (...and boring) until I made this time-lapse video:

The video is composed of  photos taken at intervals of one minute from one another.
It shows that despite having very few fish in it, this aquarium is filled with life.

Making this time-lapse movie was a breeze; it did not require messing around with electronics, utilizing special camera controls or buying software.  All it took was my fairly basic Canon camera (nothing fancy!), free software and... curiosity.

Taking the shots was by far the most fun part - the camera volunteered to do it automatically for me:
Turns out, many Canon cameras have a brilliant feature for 'temporary hacking' them - the "Canon Hack Development Kit" or CHDK.
CHDK essentially unleashes the camera's full powers without permanently modifying it -- for free!
You could make it take RAW images, detect motion, even play mini games. It rocks.
I used one of the intervalometer scripts, it worked on the first try.

The photos had enough resolution to allow for 'zooming in' on interesting areas. So the next step was to crop multiple photos at the same coordinates, and I didn't want to do that manually.... JPEGCrops came to the rescue.

To combine the shots together to a movie I used good-old Windows Movie Maker.


Thanks for reading!
