Abstract

This invention relates to a media exposure device for directly exposing a photographic print medium to radiation emitted from the device. The media exposure device comprises a plurality of radiating members (12), each radiating member including a set of radiating elements (26), the radiating elements (26) in the set being spaced in a predetermined pattern; each radiating member (12) being fixed in relation to at least one other radiating member (12) such that corresponding sets of radiating elements (26) of each of the radiating members (12) form a continuous set of radiating elements (26) in a predetermined alignment, and radiation modification means for modifying and emitting from the device radiation originally emitted by the radiating elements, the radiation emitted by the device being focused onto the print medium by the modification means at a distance which is within a particular range of distances from the device thereby to expose the print medium. A media exposure system and method, and method of manufacturing the same are also disclosed.
