ABSTRACT:
A video presenter for radiating light toward an object, such as a film negative or transparency, includes an illuminating unit detachably installed within a pallet supporting the object for photographing. To obtain a superior-quality image by uniformly passing light through the object, a recessed portion is formed in the pallet and the illuminating unit is detachably inserted therein. The detachable nature of the illuminating portion permits it to be used apart from the video presenter for other purposes. Further, the illuminating unit may include a diffusion panel for diffusing light emitted by plural light sources; the diffused light being directed upwardly to illuminate the object.
