The image did change without the filter, but I wanted all visible light removed so I took a small piece of photographic film (negative) of a white picture and put it in the place of the old filter. I think I once read that should only block visible light.
Here is the result. I think what you see are near infra-red NIR (IR close to red) images. It sure is not a night vision camera. It actually needs daylight to see anything at all. With an infrared lamp it would work as a night camera though, but no cool "heat" images. Here is the world in (near) infrared through my webcam:
the grass is all white:

Been sogging again Annom? :)
Wow, very cool! The grass being white is a good indication of capturing NIR because vegetation reflects highly in this wavelength.
What does it look like without the photographic film? Do you get a CIR like image?
You don't get heat images with NIR, you need longer wave infrared for that.
interesting expiriment!
indeed interesting. probbely a stupid question but what makes the 10 euro bill lighting up?
wiki not a stupid question, I was wondering the same thing. Strange material probably.
Thermal infrared is from 8000 to 15000nm btw.
