TimeStamp Analysis Program This is a simple java program that processes a set of JPEGs resulting from KAP sessions, telling you the interval between each photo and the next, the average interval and some general EXIF info (derived from the first image in the session). The program runs under Windows XP, Mac OS X and possibly Linux and seems to cope with cameras from Canon, Pentax, Nikon, Samsung, Hewlett-Packard, Sony and Olympus (it probably works for most camera that support EXIF).
CHDK As a tribute to those who've created CHDK - a mechanism for enhancing the power of many of the newer Canon Powershot cameras, I've done some work in that area myself.
CHDK2 The Gentled CHDK2 lets you connect two servo channels to the USB port of a CHDK-enabled Canon camera. Scripts running in the camera can detect joystick movements on the two channels and carry out a variety of actions in response. I've written a number of scripts for the CHDK2 as well as a "how-to" document on scripting.
