I can't know which model you have but Gphoto (from memory) or other photo tools can do this.
In short, do your research on your camera or soon to own camera first.
Is it possible to connect a digital camera to a computer (like USB2, Firewire, anything) and taking pictures every, say, second and send them to the computer immediately? Like a super high definition but low fps webcam?
Everything helps, thanks in advance!
