Summary:
The introduction of blue or UV sensitive contact films and papers for roomlight handling has presented new requirements for exposure light sources. High intensity lights with enhanced blue and UV output are now used in quarters that are often limited in ceiling height, space, and ventilation. New housing and cooling designs assure safety and comfort. Reflectors have been designed to cover large areas under such confined conditions. Combined with the quality of new sensitized materials the results have been remarkable and favorably compare with conventional contact work produced in a darkroom. Consistency of exposures through accurate light integration has become more difficult with varying enclosures and high ambient illumination levels. Using appropriate filtration and moving the sensors closer to the source a high degree of repeatability has been shown. A look into the future highlights microwave technology as one option for further exploration.
