Difference between revisions of "RGB Filter for Compact Cameras (Q36246)"

Reveal the hidden IR spectrum world with a RGB filter. Sky turns red, black clothes and hair look blue, flowers glow in the light blue bushes and a whole lot other neat stuff :) The way this works is that the negatives create pictures by blocking the red, green, blue colors and when you stack a whole bunch of fully exposed films together, only other wavelengths go thru. And when camera\'s sensor can detect (and show) IR light, you\'ll get pictures exposed with only infrared light. (I first saw this in a HackaDays article years ago but in that they also removed IRfilter from the sensor. I haven't done that so exposure times are measured in seconds -> CHDK comes handy)
