Our Art Club wishes to be able to 'video' art demonstrations and then project close up work in real time much larger on a screen nearby.

I suspect that an HD webcam could be used to connect to my laptop and then onto my computer projector (both of which I already have).

I don't need to record the demonstration, just be able to project it at large size whilst it is happening.

Simultaneous sound capture and amplification through the PC would be an advantage.

I think it would need to be mounted on a tripod some 10 feet away from the subject but focus on an A3 sheet of paper on an easel.

Has anyone any experience of this and can recommend equipment that would be suitable.
