In several courses I teach students make presentations standing next
to a projection screen (computer projector). I'd like to get a record
of the presentations in which both what they're projecting and the
students are visible. It seems to me this ought to be possible by
having the students stand next to the screen and lighting them with a
luminaire that has a cutoff so that they're illuminated, but not the
screen. From my reading the device for this kind of control is called
a "barn door".

We'll be recording several days of presentation at a time using a
digital camcorder (Panasonic PV-GS39).

My questions:

1) Does anyone have experience doing this kind of work, and if so,
does what I propose make sense?
2) Do you have recommendations for the kind of lights and barn door
(or other device) I should purchase. I don't have a signficant budget
for this so price matters.

Thanks

Jim Mitchell
