No two people in the world see color in exactly the same way. And while no one else sees color precisely the same way you do, you might expect that your digital camera can. Unfortunately it doesn't, because variations in color that the human eye can distinguish greatly exceed those that your digital camera's sensor can discern. This is why Tribeca Imaging Laboratories developed DCF Full Spectrum, a Photoshop compatible plug-in designed to adjust the colors in images taken with your digital camera to make them more closely resemble those you remember seeing. According to the company, DCF Full Spectrum is a "color difference model" that adjusts the RGB color model values of an image to more closely match human color perception.

DCF Full Spectrum, accessed through File>Automate, is easy to use with just three presets: DCF Full Spectrum for overall correction, DCF Portrait for improved color accuracy and lowered contrast, and DCF Vivid for more saturated colors with accentuated highlights and shadows. From the main DCF Control Panel, you can make adjustments manually to tweak the chromaticity of different hues by moving individual sliders for red, yellow, green, and blue. The main control panel also provides sliders for Spotlight and Fill, which provide some lighting control. DCF Full Spectrum can save profiles you create for individual cameras that can be recalled later and applied to other images taken with the same camera.

True to its word, Tribeca Imaging Laboratories DCF Full Spectrum doesn't affect exposure, color temperature, or white balance. DCF Full Spectrum works very well: The results are subtle but the improvement in overall color accuracy is clear. The DCF Full Spectrum plug-in from Tribeca Imaging Laboratories delivers on its promises and does it affordably.
