Infrared photography involves using available light, but specifically the part of the spectrum that our eyes are not sensitive. The light we see is a very small part of the electromagnetic radiation, part of a given length. To one side we have small waves, the famous ultraviolet, X-rays and gamma rays. Those for the other longer, the infrared, microwaves and radio waves latter. The infrared photography is rather used because it is outside our ability to see it, but we live it flooded. The sun and artificial light sources generate a large amount of infrared light, but particularly so does the heat. Any body temperature exudes a certain amount of infrared radiation and that is why this type of photography is associated with night shots or the ability to see in very dark situations. A unique feature of this range of the spectrum is that it is not easily deflected. If you put a prism in front of a light source, this will leave the beam and separate colors, in addition to altering your trip. Infrared light, however, will travel through this without distortions and continue your way straight. How infrared photography works? This quality makes little surprisingly, the infrared light from passing through your skin smooth your clothes which, in combination with a specially prepared camera can see through your clothes. A camera that has the ability to capture infrared light is practically a machine voyeuristic. If you take a photograph of a person-alive, since it has to generate some heat-with an infrared filter, you will probably end up with an image of the same person, but naked. Of course, the matter does not work perfectly all the time and the picture will not be clear, but the details important will be there. A thick or a shirt covered with dense thread will block all light. But fine fabrics, simple fabrics and nylon are especially vulnerable to infrared light and this passes directly through these materials, sending a naked picture of yourself to any camera this around. The interesting fact is that all cameras are sensitive to this light to some extent. Being part of the spectrum we can not see, capture the image with this information adds artifacts in our perception should not be there and concluding in an image without contrast and acutance. To solve this problem the manufacturers put IR filter in front of sensor that block much of this. Some cameras exploit this flaw But other cameras exploit this flaw and marketed as night vision devices, the Sony Handycam probably as a flagship product. In 1998, the company sold this model with the ability to remove the IR filter using a button, which made her sensitive to this light and allowed to see at night. The engineers did not realize until after it sold, nearly one million units of the camera could be used to see through clothes, issue which forced Sony to withdraw from the market and develop a version that was not as effective in time to capture this light. But all is not lost for the modern evil. Infrared photography or cameras are still marketed and, here comes the interesting part, companies are almost exclusively dedicated to the lenses that can see through clothing. Kaya Optics advertises its products as a powerful IR filter, but directly as a lens that sees beyond the ordinary. Their products can not only show how to see through clothes, but also through paper, ink and even even thick fabrics such as coats. If you want to be more discreet and want to do infrared photography special with your mobile, provide a version of a flexible material is printed the optical filter, which placed in front of any camera phone becomes a real X-ray machine or more While triple X.
