Introduction to Color Filters in Forensic Photography

Abstract

A filter is a transparent material that absorbs some colors and allows others to pass through. A color filter is the sheet of transparent material which modifies a light beam by absorption of some colors with respect to others. A neutral filter absorbs all wavelengths equally and merely serves to reduce the intensity of a beam of light without changing its color.  The color filters are mainly used to enhance the quality of the particular object when captured. It only allows the particular frequency of light to pass on and radiate only such amount of light.
