The heat will affect the film no differently than any other film. In other words IR film is not sensitive to that part of the IR spectrum.castilg said:Be carefull as to not leave the camera or film in the mid day heat ,the long exp time may fog the film.

This is so much easier than what I've planned. Why does the plate on the left have 10 mm of rise? How does that make the picture different?
Did you figure out optimal focal lengths, how far to extend the bellows, when you chose the pinhole size?
How do you visualize what you're recording, a template on the ground glass? There should be a formula here, maybe the pinhole designer site can help me think this through.
Did you decide on the size of the viewing pinhole by-guess-and-by-gosh? Do you know how big they are?
The plate fits under the latch, right? I can't bear the thought of putting tape right on my camera!
Thank you for your patience!
