Subject: [Leica] IR flash units?

I think the Kodak Gelatin filters are expensive because they're "optical
quality". You don't need optical quality gel on the front of a flash.

I've used both optical and non-optical quality gel to make filters for
lenses. I can't tell a difference. 

I have homemade IR filters in every size. I removed the nasty UV glass
from mostly junk filters replaced it with cutouts from gel I've had
forever. I never shot enough IR to justify buying expensive IR filters.


Filters that use a screw-in retaining rings work best. Cheaper (most
newer) filters use tension rings. You can't tighten them down on the
gel. 

I used to go to a camera show at least once a year for projects like
this. Haven't been to one in a few years, though. Are they even still
around?

Calumet Photographic has much better prices on the 87c gels.
