How do I customize a camera for x-ray , green screen, see through vision.?

I once saw an article in Popular Science and some free newsperiodicals. The camera was capable of seeing through peoples clothing.How do I customize a camera for x-ray , green screen, see through vision.?
Oh brother, is that legend still going on? You need to perform surgery on your camera (like ruin it for regular photos) to modify the sensor chip. Then you'd mount a specialized filter on the lens. Finally, you'd need to have your subject in the correct IR lighting.



There are/were Sony videocameras with Nightvision, that with the proper filter allowed for "x-ray" videos.



Better yet, read articles in Pop Science with tongue-in-cheek, as they've run articles on flying cars and such for years.
It is the heat (IR) that some cameras sensors can detect that gives the illusion of "seeing through" clothing.



The cameras that have this characteristic are rather old. Newer cameras have a "hot mirror" that absorbs all the IR light rays that enter the lens before it gets to the sensor.How do I customize a camera for x-ray , green screen, see through vision.?

Infrared is not heat, nor is it X-rays. However, infrared wavelengths do pass through certain materials. Generally, such IR viewing works best on a camcorder, not on a still camera.



To prepare your camera to see in IR, you'll need to first determine the filter size of the lens.



Next, you need to purchase the appropriate filter that blocks normal light, but lets IR pass. You also have to hope that the camera doesn't have too strong an IR blocking filter. Get the wrong filter and you'll need exposure times measured in minutes.



As it is, you'll need exposure times in the range of 15 to 30 seconds to get good IR images, because what little IR gets through doesn't affect normal images but it's too weak for a normal exposure time. Try for a filter in the 720 nanometer range which isn't blocked too badly.



Switch your camera to a night vision mode if it has it, and/or a black and white mode.



Camcorders do work best, especially in night vision mode, for IR video work.



Alternative: get a camera specialized in IR work, like the

FUJI FINEPIX IS-1 VISIBLE PLUS IR KIT



Another alternative: have your camera altered to remove the IR blocking filter. There are companies which do this, although I can't vouch for them:

Good luck!
Just put your X-ray specs in front of the camera lens.
