Several years back when I was helping the S&O team set up at the
Formulary, Mark and I used a bank of UV tubes, like the ones used by
many alt printers, to make an exposure. I don't recall my exposure, but
it worked great. I however, was only trying to light a small table top
set up with a 24" light bank.

Subject: Wet Plate, Hot lights & Strobe
I'm wondering if anyone on the list has used wet-plate collodion with
artificial light-- either hot lights or strobe. Since daylight exposures
range from, let's say, 4 sec. to 15 sec., what would a hot light
exposure be?
I guess with strobe you could use several pops with the lens open, etc.
Now that I think of it, can anyone give me wet-plate exposure guidelines
for
natural light? As I understand it, a light meter is not really useful
with
collodion, but a starting point might be an ISO of 1. Also, the
sensitized
collodion seems to vary widely from batch to batch, or as it ages. Any
thoughts?
Folks seem to say that the only way to judge exposure is by "trial and
error," but that's both time wasting and expensive.
