Infrared light is not visible to the human eye/brain system, therefore no infrared light is perceivable as "color", or even "monochrome" to the human eye. Infrared light is a range of wavelengths of the electromagnetic spectrum that are outside the range of wavelengths that produce a chemical response from the cones in our retinas.

Oct 9, 2014 · The composition is called CIR (color infra-red) And it uses IR->R G->G B->B There is a known phenomena in vegetation called the 'red edge' which causes vegetation to reflect more light in a narrow spectrum in the IR due to their chlorophyl content. scientific explanations aside, this is really useful: many satellites use this for agriculture ...

The color filter array is typically right on top of the sensor, under an infrared filter panel. After removing the IR filter, the CFA can be mechanically scraped off of the sensor: Effects of this destructive process are detailed here.

Feb 12, 2014 · Yes, infrared photography does record infrared wavelengths. Usually, a filter is used to make sure no visible light gets recorded. Sensors and films are not based on human eye, so their limitations are different. We can see the infrared light on resulting photographs because it is displayed in some other color(s) than infrared.

Sep 1, 2015 · About filters: knowing now that infrared photography could not exactly be what you mean, if you desire to snap pictures with an analog camera loaded with infrared (color) film (assuming you still have one - since they have been discontinued) and you want to use a filter to obtain "infrared pictures", then buy an infrared filter. This kind of ...

Jul 30, 2012 · Finally, if you want to do an image that shows light red color, dark blue colors and the heat over the objets, you must buy a 650nm, 680nm or 720nm filter. If you want only the heat you must buy 850nm, 950nm or 1000nm. i.e.: 650nm-720nm. 720nm-1000nm. In adition of all of those complicated things.

Sep 16, 2018 · \$\begingroup\$ The most characteristic thing in IR photography is that green plants reflect large amounts of infrared light which is visible on photos as white, snow-like colour. Here with the 680 nm filter there is no sign of white colour, only dark grey or even black - see the last photo where white balance is correctly set.

With infrared I would strongly advise shooting RAW and setting white balance in post. When I started shooting infrared, I found the standard Lightroom adjustments didn't have enough latitude to white balance infrared, so I had to create a custom camera profile. The point is that the color shift you get is extreme.

Oct 24, 2021 · ¹ The 'red' filters of a typical Bayer mask are actually a yellow-orange color. This mimics our retinal cones. Our 'red' retinal comes are actually most sensitive to a lime-green color of light! The 'green' cones are usually most sensitive to slightly yellowish green and the 'blue' cones are actually most sensitive to a violet-purple color.

Jul 17, 2012 · I have some frames of a security IR camera. The images are black and white. Is there any way to represent these images with colors. I use GIMP in Ubuntu operating system. Thank you!
