Re: MACO IR 820 fogging problems

[Eckhard Stephan <eckhard.stephan@xxxxxxxxxxx>]

Hello everyone,

I found out the reason why my MACO IR 820 was fogged: The plastic
container of the film as well as the tin cassette itself are NOT
IR-PROOF. I fogged the film while I let the firmly closed container
stand outside the fridge for about half an hour to acquire room
temperature. Fortunately it was only one roll...
This evening I performed a simple test: I cut off two little pieces of
film from a fresh roll of Kodak HIE in my darkroom. I put the first one
in a HIE plastic container, which I know to be IR-proof, and the second
one in the MACO container. Then I turned on the lights for some minutes.
After that I developed the two film pieces as usual. The film from the
Kodak container was fine, whereas the one from the MACO container was
completely black.

This means that YOU MUST NOT OPEN THE TIN CAN OF MACO 135-36 EXCEPT IN
ABSOLUTE DARKNESS.

Hopefully this warning doesn't come too late... 
  
Cheers, 

Eckhard
