CPOL + IR?

[Markw]

Will a CPOL filter have any effect on the image produced from an IR-only DSLR?

Thanks,
Mark

I don't know. Will it? Polarization (waves) - Wikipedia, the free encyclopedia

IR is just a wavelength of electromagnetic radiation humans cannot see.

Okay, but I doubt that will tell me the effect it will have on an IR image. I understand that, but I would like to know if anyone knows the specific effect it will have on an IR image.

Mark, on your site link, the 3rd image(s) of the clouds side by side....if you cross your eyes the image becomes 3D. Which neat, because it wasn't intentional. :lmao:

Light is light, the wavelength doesn't matter. In other words, even the wavelengths of light humans can't directly see, can be polarized. http://en.wikipedia.org/wiki/Electromagnetic_spectrum
