A friend is looking to use either photo paper of
photo film in a performance art piece he is doing and he wants
something with an exposure time of about 5 minutes...meaning a change will take
place and be seeable by th audience in that much time.
Is there such a matter? I explained that some of
the time length will have to do with the stage lighting but I just didn't know
of films or papers that take that long to react to light.
Any ideas on what might?
Thanks,
Lea
