Hello David, and thank you for your suggestion.
That would work I think. There are some Canon cameras that can be controlled by the animation software via USB, so you're seeing the shot in real-time on your monitor. Also, things like 'onion-skinning' can be very useful when moving the object you're animating.
Unfortunately, Canon has disabled that on this model, in favour of some very dubious features. I'm sure it's a very good camera, and it's made even better with the CHDK, but for what I want it's a disappointment.
I haven't tried triggering the camera with the CHDK and a USB remote cable, as described on this site, but that could be a way to go.
For now it's back to the web-cam for my animating efforts.
Thanks again,
Steve
