发明名称 Close-up attachment for a digital camera
摘要 A kit for modifying a digital camera of the type including a built in flash, to perform close-up photography includes a mounting plate attached to a camera around a camera lens, a lens plate having a secondary lens selectively attachable to the mounting plate so that light entering the camera lens is first magnified by the secondary lens. A bracket assembly is selectively attachable to each lens plate to indicate the location of the focal plane and the size of the image frame. A flash attachment adapted for close-up photography includes a flash output window, a power switch, a mode switch and a flash intensity switch. The flash attachment is secured to the camera and wired thereto so that the mode switch may control which flash unit, the flash of the camera or the close-up flash, activates. The flash intensity switch is a rheostat and controls the amount of light emanating from the flash source to the subject, according to the distance between the camera and the subject.
