Hey everyone, sorry about the off topic post but I recently bought a new Canon point and shoot, the A720IS. I discovered during my online research that a open source code for Canon cameras exists that allows these little point and shoots to do some amazing things. I've installed it but was wondering if anyone on the list is familiar with it? It's called CHDK I'm particularly interested in the manual exposure overides and the timelapse and "lightning" shots that this will allow, seems to have a steep learning curve and I'm impatient and wouldn't mind having a local guru to help out. Thanks! Howard
