Re: [Rollei] Infrared film for the Rollei

[Nathan Wajsman <wajsman]

Hi Philippe,

The Rollei is ideally suited to IR since you do not have to look through
a lens with an almost opaque filter on it.

My favorite IR film (both 35mm and 120) is the new Maco 820c, made by a
company in Hamburg, Germany. It is less extreme than Kodak's IR film but
gives you more of an IR effect that the Konica or Ilford SFX films.
Check out:

The recommended filter is Heliopan 665 or 695, which yields a speed of 6
or 12. I know it is slow but anyway you are going to be using a tripod,
so it should be OK. You can also get nice images with a dark red (29)
filter. I am pretty sure all of these are available in Bay I mounts from
Heliopan (or their equivalents from B&W), or you can get an adapter so
you can use regular screw-in filters.

As for focusing, I usually do not worry about adjusting focus. There is
some formula out there for how much closer you need to focus with a
given distance and focal length, but if you stop down to f8 or smaller,
then it should not matter.

On my picture-of-the-week web site:

I have some examples of pictures shot with this film (35mm version).
Look at weeks 34 and 42.
