Before I load up my beautiful roll of Kodak HIE Infrared film, I thought I should be completely clear on how to shoot it. I know that with film, the only filter you really need is a red filter, but my question is on exposure. Will the internal light meter be reasonably accurate, or do I sort of guess on exposure? Also, if anyone knows anything about the Nikon 2020 body, does it fog IR film, or will I be fine? Thanks!
