IR film and EOS cameras

[Jon <mr645@xxxxxxxxxxxxxx>]

One of the top wedding photog on the west coast, who is also well known
for infrared bridal images  recently did a test using Kodak HIE in his
EOS A2e camera.  Here is a copy of the post from the AOL message
boards.  I would be interested in hearing if anyone has had different
results.

Attention all you infrared shooters, or wannabe infrared shooters:

A week or so ago we had a discussion here on whether one could use Kodak
High Speed Infrared black and white film in a Canon A2 camera. It seems
that the camera uses an infrared tracking beam for film advance. (I
suspect other newer cameras have a similar system as well.)  

I said I would test to find out.  Well, the results are in.  (Sorry for
the delay, it's been kinda wet out here lately.)

The Canon A2 DOES fog the Kodak black and white infrared but mainly in
the non-image area (sprocket holes), where the fogging is quite dense. 
There is a very very slight fogging into the close edge of the image
area but in my opinion it would have little effect on the actual images.
It is very slight and only along the edge of the image area.  At the
most it might require some slight burning in on the print at the very
edge if you were printing that area off of a thin, underexposed infra
negative.  I exposed the film to images and also ran some frames with
the lens cap on to see the fogging on clear, unexposed film.  

My conclusion is that I would not hesitate to use Kodak High Speed
Infrared film in a Canon A2 camera.  Have fun, shoot away!  Remember to
load and unload the film in complete darkness with ANY camera.

Incidentally, my exposures tested best at full sunlight at 1/30-1/60 @
f/11 and flash at ISO 100, on automatic.  With a 25A red filter.  D76
straight 8.5 min at 68 degrees.  For the daylight shots I did not use
the camera's meter, just set manually.

Have fun all you infra folks.  Glad to help out here.  And Tom .....
remember the red filter!  :-)

Best regards,

Rick Rosen
