No! This magazine contains so much crap, the latest example is the
slide film test in 7/97, they found that you have to add 1,5 stops at
10s for Kodak Elite 100 II! My pesonal observation is that this film
does not show any reciprocity failure up to several minutes!

The german datasheets about Kodak IR-films claim that this films must
be loaded in total darkness, so its no wonder that ColorFoto writes
the same.

The author writes that the due to the lack of the antihalation layer
the filmbase guides light in the 'box' (sorry don't know the term).

BTW: Once I had the chance to see how good antihalation layers work.
     My trusty old Minolta X-700 crashed on concrete and the back
     opened, it took some seconds to close the back. Seven
     frames were exposed (five were total ruined, the two other
     showed partly).

Wow, -30 DIN, thats 0.00125 ASA! Using the 'Sunny 16' will give you
800 seconds exposure time plus reciprocity failure ... try a long
time exposure with one or two hours ...

BTW: Does the negative show any IR-effect?
