Most professionals do some level of experimentation and home-brewing, we just know how to discern quality and chose what works. Try different blocking materials on the same sensor and see which ones have the least scattering/best IR transmittance. Refine it and share your results... ignore those who tell you not to use your minds and experiment.

Unexposed slide film is no good as a filter as it still has layers of red/green/blue dye emulsion that have not been dissolved by processing. slide film records the actual image in it’s dyes and emulsion ,normal film records a negative that is used to print ‘positives’ on photo paper.

This afternoon I've just got developed film for IR filter. But maybe i misunderstood, I went to camera shop, bought 1 roll of film, after that i requested them develope that film. But when got bach developed film, it looked like clear & red color. I try to take picture with that developed film cover and picture look like red filter (my camera is Canon 350D). I think I had mistake, before develope film, maybe i need to roll out film. This is correct or not, please instruct me. Thank you and hearing from you soon Dear all

It does deteriorate and is easily damaged... and who knows what actual wavelengths are being passed. I now use glass IR filters on the camera, but I still use developed unexposed film as IR filters on strobe heads... Makes the flash less obtrusive ;) I'm a serious photographer (I don't take myself too seriously though) I've put pieces of panty hose behind 20,000 dollar lenses (film) because it gave the right "look"... so there.

This idea does work, it's a given, but why would you do it? Have you ever wondered why professional lenses are thousands of dollars? There are many reasons why, one of them is that it will give you quality/sharp more detailed image. Adding film over, or even worse - taping it on the back of your lens, will only take away from the quality of your current lens, or it will slightly distort your image. "You" might not notice, but take it to a professional photographer and tell him/her what you've done. IR filters can be expensive because those expensive ones will try to match and blend with the quality of your top of the line lens. That is why, there will be less or no distortion at all, and it will not take away from everything that your "top of the line" lens has to offer - if you use a real filter that was designed for you lens. (There are different lens/filter sizes.) Adding this nonsense to your lens is like wearing the wrong glasses. You get your eyes checked once in a while, and if you need glasses, as you get older, your prescription will change, and your glasses will change optically. If you wear the wrong glasses your vision will be slightly distorted. Once you put the right ones on, you will notice the difference and will dispose the old ones. Your lens is your third eye, so wear the right glasses if you need so. I read a lot of these comments here, and I don’t think there is one serious photographer here.
