The Hutchcolor scanner target, developed by consultant Don Hutcheson, has 500 color patches and is made to the full gamut of the Agfa, Fuji, or Kodak film or paper on which it is made. The Hutchcolor scanner targets, also available on Agfa, Fuji, and Kodak film and paper, consist of 500 color patches imaged to the media's full gamut. With these color gamut limitations in mind, color consultant Don Hutcheson, who used to be an engineer with the British high-end scanner manufacturer Crosfield (now part of FujiFilm), designs and manufactures his own targets. Thus the film you're using may be capable of brighter, more saturated colors than those represented in the IT8 target. The IT8.7 targets are made to a specified color gamut that all color print papers or films, respectively, can achieve. print, 4x5' transparency, and 35-mm transparency. The IT8.7 targets available from Agfa, Fuji, and Kodak include a 5x7-in. Scanning targets include the industry-standard IT8.7 targets, which were first developed by Kodak as the 'Q60' targets and then turned over to the American National Standards Institute's (ANSI) Committee for Graphic Arts Technical Standards (CGATS). Scanner profiling targets include (clockwise from lower right): the standard IT8 288-patch target, the 500-patch Hutchcolor target, and GretagMacbeth's i1 RGB scanner target. These programs apply smoothing to the color target capture, and look outside the color gamut of the profiling target so that bright, saturated colors in subjects will be covered by the profile.

You can profile a digital camera with a scanner-profiling program, but GretagMacbeth and Monaco have separate utilities for profiling digital cameras. Leading programs for scanner profiling include those from GretagMacbeth, Monaco, Creo, and Heidelberg. This works best for repetitive studio shots, such as catalogs, where the lighting, subject distance, and other variables don't change. Since a digital camera is basically a scanner attached to the back of a lens, you can also profile your digital camera. If several scanners are profiled to match the original, then these scanners produce calibrated output and agree with each other. The result is scans that match the original. The program then builds a profile that corrects the scanned colors to agree with the actual colors. A profiling program compares the colors in the scan with color measurements of the target, which represent the 'actual' colors. It works by scanning a color target of several hundred color patches.

It's no wonder that no two scanners match!Д¬olor management software helps scanners and cameras to actually 'see' in color. These devices don't 'see' in color, but in shades of gray that are recorded as RGB values.

Color scanners and digital cameras 'separate' continuous-tone photographs by recording them through red, green, and blue (RGB) filters.
