Useful CHDK add-on that allows for time-lapse photography
Saved by: Paul on 8 May 2016
A temporary (or permanent) set of tools which you can use to enhance what a lower-end Canon camera can do. You put it on the SD card that goes in to the camera, then load it in when you need it.
Motion detection add-on for the Canon Hack Development Kit - adding motion detection triggered photography to Canon cameras that don't already have it (i.e. pocket or 'bridge' models.) Works fine with my Powershot S2IS model.
