4x5 film holders

["phillip geller" <filje@xxxxxxxxxxx>]

FYI
After doing some new tests with the maco ir in 4x5  i looked
at my film holders with a sony camcorder in nighshot mode.
What i discovered is that all the holders and dark slides are ir safe.
The taped bottom flaps can leak light but it appears to be negligible.
I have all kinds of holders  Riteways Lisco Regals Fidelity etc.
The odd thing is... The newest most expensive type of holders -
Riteways with the locking darkslides and film index numbers inside-
reflect IR off the black painted metal on the inside. They look
light grey in IR compared to all the others which are really black.
Also all the light traps appear  black and not white in IR like
some of the 35mm cassettes.
