Been interested to find our more about finding a suitable IR low-pass material to fit my Sigma Fisheye and stumble across some net article saying that exposed film are possible.
Has anyone tried using exposed film as IR filter?
I tried to use the blacken part at then end of an old processed negative but the resulting picture us like something through a red filter. Leaves on the tree were not white.
Just wana ask if anyone has tried this before and how's the photo.
The article is here.
