INFRARED PHOTOGRAPHY

For me there is no infrared photography who completed the lesson , without understanding how light it is and how it works . The usual light source is sunlight we feel in our solar system and of every thing that emit energy or power . For scientists such energy ranging from x - ray to the radio waves , they are called the electromagnetic spectrum .WavelengthEach electromacnetic spectrum have different wavelengths . Spectrum is in the category of light waves into three broad categories , namely :

    Ultraviolet light
    Looks light eyes ( visible ) and
    Infrared lightThe distance between the waves rose up to the wave down is called wavelength , the size is so small that using size nanometers or 1/1 millionth of a meter .Visible light eyes and do not look eyein our daily life we see what is called visible light eyes , red, yellow, green and blue that we see it included into the category of visible light eyes . But not only the light waves of light that we can see , but there are also ultraviolet and infrared light , where the light can not catch with our eyes . Only the eyes visible light which is dispektrum ( sd 400 700nm ) , because the human eye can only capture wavelengths along it . The spectrum is divided to several colors ( red , orange , yellow , green , blue and violet ) , short wave will be in the category of blue waves , starting at a wavelength of 400nm while light waves are included in the wave Infrared light with a wavelength greater than 700nm . Infrared light itself was divided into two light "near infrared " ( 700 - 1200nm ) and " Far Infrared " (greater 1200nm ) .

Actually, every object that we can see and have seen these objects reflect the colors mean colors that fall into these objects. If we look at a blue object means the object reflects the blue light that falls on him and absorb other colors .Infrared photographyEssentially an infrared photography is a photography technique that try to capture infrared colors reflected by the object image . In this case the photographer who photographed with infrared techniques to try to capture the light with a wavelength of 700nm ( nanometers ) or infrared light from objects that you want to photograph . Infrared look at photos of brightly colored leaves and dark -colored sea , this is caused by the many herbs that reflect infrared cayaha fell to him and the sea absorbs infrared light that falls on him.Infrared photography on the film .On infrared photography using film , special film used to record only infrared light , infrared films are some examples : Konica 750 Infrared films , Kodak High Speed ​​Infrared and Maco IR 820c . Use of infrared films is quite difficult because the films are sensitive to heat and infrared light slightest . To beautify the images Infrared photographers can pair # 25 filter in front of the lens and infrared will produce a better picture because this filter will be whiten the color of plants and blacken the sky and the sea (assuming the photos printed on paper in black and white ) .Infrared photography on digital camera .On infrared photography using a digital camera , to get a photo infrared we need to block all visible light and ultraviolet sensors that capture only infrared light reflected by the objects we photograph .To block the light - light and infrared light is needed to get a filter with a certain material that can resist all that is under 700nm light and let through light having a wavelength greater than or equal to 700 . Such filters are called infrared filter .
