    Color infrared. A color infrared image, composed of near infrared, red, and green energy displayed as red, green, and blue highlights broad leaf and/or healthier vegetation as deep red hues, while lighter reds signify grasslands or sparsely vegetated areas. Color-infrared film at large scale (,) is favored for the task. East German investigators have used spectrozonal (multispectral) aerial photography at scales ranging from , to ,) Walker and Dahm25 developed a method for measuring environmental stress.

Usually a near-infrared band is the longest wavelength being displayed (this is especially true for MSS and aerial color infrared photography). Since vegetation is brightest in the near-infrared, vegetation turns out red. Using red for vegetation in digital data makes the digital data color scheme similar to that for color infrared film.

    The speed of the film is also an important factor: the slower color films may not be used where the terrain is too dark, such as areas of ubiquitous heavy vegetation or predominantly dark rocks. The two general types of black and white films used most frequently are the panchromatic and IR-sensitive films.

Mapping vegetation complexes with digitized color infrared film: Wisconsin power plant impact study / By Warren J. Buchanan, Frank L. Scarpace and. Color-infrared (CIR) film, sometimes referred to as "false-color," is the most common form. It was originally developed by the military for detection of camouflage, a concept based on the ability to distinguish between real vegetation and surfaces that have been merely painted green or covered with freshly cut brush or green netting.

The result looks like the world as humans see it. A false-color image uses at least one nonvisible wavelength, though that band is still represented in red, green or blue. As a result, the colors in the final image may not be what you expect them to be.

Overstory vegetation was to be mapped using more than color infrared aerial photographs ofscale in film transparency format recorded from a flying height of approximately m for the NPS by a commercial contractor (using a Wild RC20 photogrammetric camera, f=15 cm) in late October of and when the leaves were still on.

Color infrared (CIR), or false color film, is sensitive to green and red in the visible portion of spectrum of light and extends into the near-infrared region of the spectrum. Vegetation is distinctly red to magenta in color infrared images because vegetation is highly reflective in the near-infrared portion of.

Healthy green vegetation is a very strong reflector of infrared radiation and usually appears bright red on color infrared photographs (depending on how the film is developed). Natural color images are recorded in the natural colors seen by the human eye in the visible portion of the spectrum.

False-color infrared images are recorded using part of the visible spectrum and part of the near-infrared, but the colors in the resultant photographs are arbitrary and not natural. Infrared film commonly is used and is less.

The normalized transmittance vegetation index (NTVI) is linearly related to the LAI upto a value of 6 based on measurements from 42 spring wheat genotypes. LAI assessed from digitized color infrared films showed that spectral sensitivity of film is too limited to resolve differences among the 42 genotypes.
