The Magical World of Infrared Photography
The perception of color is a purely psychological and subjective colors, as we see, there are no out objectively, but that originate through the retina, in our inner mental screen. The range of the light spectrum, between 700 and 1,200 nanometers, which captures infrared photography is invisible to the naked eye, and applications ranging from art to science, as we shall see.
All hot objects emit infrared radiation
Infrared photography, therefore, need a SLR camera and a film sensitive to the wavelength emitted by objects to be photographed. All hot objects emit a greater or lesser extent, infrared radiation.
The beginnings of infrared photography can be traced back to an implementation in the military system to detect camouflage known through aerial photographs. Although its use is more widespread in the field of astronomy and telescopes by IRTS able to photograph some of that 90% of invisible matter in the universe. It also has application in medicine to detect and diagnose some types of cancer. But today is widely used in the field of artistic photography.
Spectral or Surreal Worlds
Due to the nature of pictorial shades obtained with infrared photographs, artists such as Seth Mayer, Lindsay Garrett, Donald Aaby or the prestigious Simon Marsden, with instant cutting gothic worlds have managed to create spectral or surreal.
Fictitious or strange colors white and black
Among the most popular infrared film, infrared include the Kodak, and Ilford SFX 200. A color resulting in a fictitious, and other strange black and white tones.
Experimenting with infrared cameras
With the boom of digital photography, the classic technique of infrared photography has been losing popularity. Today, infrared experiment with digital cameras is possible in some cases disabling the filter to these “hot mirror” that protects them from the radiation. With this simple operation can get some digital equipment market, by attaching an infrared filter, get infrared pictures.
Suitable filters are needed to allow only the passage of the infrared spectrum
Infrared filters are tasked to suppress ultraviolet radiation and all or most of the visible spectrum, passing through the lens of the camera only the infrared spectrum. Without the IR filter, the film would absorb the entire spectrum and leave the negative unusable.
In the market you can find various types of infrared filter, so as the case or personal criteria, such as those sold by Hoya (R72) or Cokin (P007), for example. They differ in the amount of infrared that leak. The more infrared spectrum, the effect on the film will also be more pronounced.
The digital photo editing software as an alternative
Another way is to experiment with photo editing software like Photoshop or other celebrity. Although this alternative is widely reviled by the real purist fans of this photographic technique. However, no doors to the field put no limits to the imagination …
