Therefore it enhances the creative capabilities of each photographer especially when taking photographs of unusual scenes or under exceptional lighting conditions. The Mastersix combines all advantages of modern microprocessor technology and the know how Gossen has acquired from 50 years of manufacturing light meters. The microprocessor interlinks various light metering processes for supplying useful photographic or photometric measuring information. The Mastersix can measure incident light, reflected light and also flash light. The meter is a part of a system, there are 9 optional attachments available which expands the use of the equipment enormously.
