Here is a quick & dirty test negative of 8x10 Svema 100 on my light table.
Exposed at 2 seconds @ f16 with an IR720 filter.
Developed in Rodinal 1+50 for 13 min. @ 68°F.
My cellphone and my light table don't get along, so please disregard the yellow fringing on the left side of the image.
I made this exposure to test the IR response of the film, and to test for Wood Effect in direct sun and in shade.
I look forward to using an inexpensive IR-sensitive b/w film in 8x10!
Well, that's way more promising that I'd expected. This looks like it was shot in the shade ... what are the results like in direct sun?
I need to throw a few rolls of this into my next order and give this a try. I'm curious what the spectral sensitivity curve looks like, and how deep the IR sensitivity goes!
This might give me an excuse to dust off my spectrosensitometer project and actually get it put together, especially now that I have a 3D printer and can build it as something other than an ugly lash-up
