Playing around with CHDK
I own a Canon Powershot A540, and I’ve been putting it through its paces this summer. There are a few ways in which I’ve sort of hit the limits of its capabilities; for example, I can’t do the typical slow-shutter-speed waterfall photographs because the aperture only goes down to f/8 (although I could probably hack it with a makeshift ND filter or something). Interestingly, the capabilities of these cameras are in part set by the firmware, and so there is an open-source firmware enhancement project called CHDK which aims to both unlock the full featureset of the hardware and augment it with more featureful software.
