RE: infrared pinhole

Hey Gordon.
Not a lot of IR but what the heck, get something resembling a Wratten 25 red
filter or even a Wratten 15 orangish filter & use the old film holder slide
trick to figure out some speed & if it works. I might use a regular camera
that you know is IR tight.
In case anyone doesn't know about the slide trick, it's just like checking
an exposure on paper in a darkroom. Expose for a while push the slide in
some, repeat till clean, ah done. Note the changing sun & light as you go &
just guess....

Let us know how it goes.. I've seen it around & never thought of just using
"regular" light to expose it.
Good luck

Subject: [pinhole-discussion] infrared pinhole

I recently bought a large volume of KPGraphics RRD 680 recording film - ebay
it was cheap :)

Its intended for use with a red laser - its only senstive to far rad and
infrared light.

I think it may act like infrared film. I've never used infrared film - even
in a lens camera.

Does anyone have experience doing infrared with a pinhole camera. Its
november and cold here in saskatoon - can I expect to get much infrared
radiation?

Gord
