发明名称 Close-up camera apparatus
摘要 Apparatus for converting a camera for close-up photography, includes a flash hood attachment for the flash unit of the camera for reflectively spreading a beam of light from the flash unit to distribute the light over the field of view for very close subjects. Other attachments provide for reducing the light received by an auto-exposure system of a camera, for blocking a portion of a viewfinder window to correct for parallax problems, and for covering the lens of the camera with a pin hole to convert the camera to a fixed focus camera, all for converting a conventional camera for close-up photography.
