Latest Patents
Michael H. Riley holds a patent for a "Reflectance based microfilming process." This process addresses the challenges of variations in the fade or background coloration of materials during preservation microfilming. The method involves developing a characteristic of the camera-based workstation that relates an exposure meter output with a sequence of variations of the light source used. A pseudo background target of constant hue, such as beige, is utilized to ensure accurate filming. The process also incorporates a sample card with color samples that fall within the relevant spectra of the materials being recorded. Reflectance densitometer readings are taken for each sample, and the data is compiled to allow operators to adjust exposure based on the background hue of the materials being filmed.
