ABSTRACT:
The close-up photographing apparatus includes a range determining frame having a guide plate at a front end thereof. A frontal opening defining a photographic object area is formed in the guide plate. The range determining frame allows a photographic object placed in the frontal opening to be at an optimum distance for a best photographing result. The guide plate allows the apparatus to be placed flat on a table or the like supporting a photographic object. The apparatus further includes a strobe light for lighting the object in the frontal opening, and an aperture member defining a small aperture opening which achieves a large depth of field and a proper photographic exposure in cooperation with the strobe light. Thus, the apparatus incorporates all the necessary conditions (distance to the object, lens position, aperture opening, shutter speed and lighting intensity) for close-up photography at a high magnification factor so that a clear picture of a high magnification factor can be taken easily even for an inexperience person.
