a piece of green transparent acrylic and red transparent acrylic work phenominally well as an IR filter. Better than a piece of exposed negative film. pictures soon. I bought 2” square samples for a dollar at a local plastics store. No need for an expensive IR lens. Really.
Awesome! how thick were the acrylic? is the order (green first then red?) important? Possible to post some pics on how you fit them to your cam? I have most of the parts ready except for the filter. :(
Would love to try this out. Thanks for sharing.
