The Gossen Repro is a specialised attachment for the Gossen Lunasix 3 and compatible exposure meters. It was developed for copy photography, such as photographing or reproducing documents, drawings, paintings and photographic prints.
The attachment helps determine the correct exposure for reproduction work. It can also be used to check the uniformity of illumination across the subject, helping to identify differences in brightness between the centre and the corners. When used with the Lunasix 3, an exposure correction of three stops is taken into account.
A useful specialist accessory for photographers working with reproduction, as well as collectors of Gossen exposure meters.
