Kodak 4 x 5 infrared

Recommended Posts

I live in a southern Ontario town and I asked 2 local camera stores if

they can get me Kodak infrared 4 x 5 b & w film. They said yes - but

the minimum order is 20 boxes. I have read in this forum that this

film is supossed to be discontinued. Can anyone shed some light on the

present status of this film and where I might buy 3 or 4 boxes? Thanks

.... Jack

Well, here's my suggestion: if you really can get fresh HIE (I guess Kodak will custom-make small runs) you should see who else on this forum would like to go in on a run of 20, and split the cost. Did the store owners say how much it would cost? I'm a starving student, but I might even be interested (how fun is food and shelter compared to infrared film?).

Someone above mentioned whether all bellows are "safe" for

infrared expsoure. They are not.

 

Some years ago I found out the hard way that my Wisner bellows

(both normal accordian and bag WA) made of red kid leather will

not block IR radiation and ruined a weekend's worth of shooting.

Wisner does offer a synthetic bellows specifically for IR, but it's

neither as long nor as flexible as the otherwise excellent kid

leather ones.

 

As far as I know the Wisner is the only brand with this problem,

though I'd recommend testing (with an IR sensitive digital

camera) before shooting any camera in question.

 

Hope this helps.<div>003hR7-9331184.jpg.73c55d23d363efd1fef4da2ba52856ca.jpg</div>

I'll take a couple of boxes too.

 

I recently shooted Konica IR 750 in 6x12 size with my Sinar F2. The bellows are safe. But this film is only sensitive up to about 820 nm. Kodak HIE are sensitive up to about 930 nm. You can try the bellows as follows:

 

- First do this: put a TV remote control into the bellow, and point it to your TV, at one inch before the TV sensor, the bellow between the remote control and the TV sensor. If you are able to change the programms, your bellow is not IR proof. If you are unable to change the programms, the bellow MAY BE IR proof up to 904 or 1060 nm, depending on the IR Diode type. In this case, try the following test:

 

- cut a piece of HIE 35mm and depose it into the bellow, with a small object over part of it, like a penny. Let the camera before the sun one or two hours then develop the film. If the print of the object is visible, the bellow is not IR proof.
