4x5 IR sheet film availability

[thomas_kienstra]

I was wondering if anybody here could tell me who still supplies infra-red black and white sheet film? I understand Kodak produces the HIE only in 35mm, and I believe Ilford's is the same way - 35 only. Any 4x5 stuff out there? And if so, who still sells it? Thanks for any advice...

As far as I know, Macophot is the only current supplier of 4x5 IR

sheet film.

Ilford SFX is available in 120, and Konica is available again, too.

Here is my impression of Macophot: It's OK, but it has quirks.

I tried Macophot when it first came out using my favorite developer,

Xtol. (I've heard D76 gets better results) The test rolls of 35mm I

shot wound up having a speed in Xtol of 1-1/2 to 3. Also, the film

does not like to be wet. Only let it be wet for 30min at most. After

that the emulsion becomes foggy, like there's a zillion air bubbles

in it. I gave away my last roll instead of shooting it.

Hello Thomas

 

<p>

 

I don't know whether this will help but here in the UK a dealer

called Mr Cad (www.mrcad.co.uk) sells Maco 820C 5 x 4" sheet film. I

have used some in 35mm format but have not processed them yet and

therefore cannot advise of the results.

 

<p>

 

According to a book I am reading by Hugh Milsom (called Infra Red

Photography - A complete Workshop Guide) it should give results

similar to the Konica film.

Mr Cad sells the Maco IR for £36 UK pounds for 25 sheets.

The Macophoto 4x5 film IR 820c is available in the US. Try your

favorite retailer, or B&H, Calumet, Adorama, ....

The manufacturer's website is http://www.mahn.net/

Compared to Kodak HIE, it has an anti-halation background so you won't

get the same halos around highlights. It doesn't go as deep into the

IR, so you may need a filter with a cutoff at a longer wavelength to

get the same effects, such as white vegetation.

I've been fairly pleased with the Maco 820c IR film in 4x5 (which is

the main format I use the film in). Try it and see. Not only less of

a halo than the Kodak offering, but less severe IR effects -- at

least with the IR72 filter. I have a web page on the film with exx

from 35mm format at

http://darkwing.uoregon.edu/~epederso/Photo/IR/Test.html

I'll be updating that page next month after I finish some tests with

IR filtered strobe light.

It's the only game in town for 4x5 IR work, so if you are interested

in such, then you need to find a way to make the film work for you!
