Title: Siegfried Barbieri: Innovator in Photographic Technology
Introduction
Siegfried Barbieri is a notable inventor based in Brixen, Italy. He has made significant contributions to the field of photographic technology, holding a total of seven patents. His work primarily focuses on enhancing photographic processes through innovative lighting and color measurement systems.
Latest Patents
Barbieri's latest patents include an illuminating system for photographic color enlargement or copying. This system features a light source that generates a beam of light with a specific energy distribution across three wavelength ranges. These ranges differ from the spectral sensitivity of photographic copying materials. To address the disparity between energy distribution and spectral sensitivity, color filters are incorporated into the beam of light. One filter influences the wavelength ranges with the highest energy levels, while a second filter targets the range with the largest energy excess.
Another significant patent is an apparatus for determining the color composition of printing light in a photographic enlarger. This apparatus samples and measures light within the intermediate diaphragm chamber of the objective lens. It utilizes color-sensitized photoelectric transducers to determine the color content of the light. The design includes a light conductor that can be adjusted and features a removable diffusing element for enhanced accuracy.
