ante Posted November 26, 2005 Report Share Posted November 26, 2005 Many digital cameras have a larger receptive spectrum than the human eye this is why we can see IR through a camera! Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted November 26, 2005 Report Share Posted November 26, 2005 Ante is right but:I can just about see a dim light from the LED on my car's central locking remote control.LEDs often emmit some visible light too, whether you can see it or not depends on the wavelength of the LED, whether it has a filter and how good your eyes are at the red end of the spectrum.
