I was reading a photo book on digital photography and it mentioned Infrared and digital cameras. I had no clue the ccd element was sensitive in this range. ( you can find out if your camera is by observing your cameras active rear viewing screen and aim your tv's remote control unit at the lens. Actuate a key and if you can see the remotes led flashing, your almost set. Some cameras have this sensitivity disabled.)Lastly you need to shell out 40 bucks or so for an infrared filter. Mine is a Hoya (Ifrared) R72. The two photos here were taken as such: One without a filter, then made into a greyscale image in Photoshop. I corrected for grey levels. The other with the filter, converted to greyscale and corrected for contrast,gamma etc. The exposures were set by the camera. No data. Hope you will like to explore this. I will post others soon.
