The HKDW-905R Slow Shutter and Image Inverter Board** powerfully enhances the operational and creative versatility of the HDW-F900R camcorder. With the HKDW-905R equipped, the camcorder can slow its shutter speed down to a 64-frame period*. During such a long frame period, electrical charges accumulate on the CCDs, dramatically increasing sensitivity. This helps camera operators to shoot in extremely dark environments. In addition, because more picture blur occurs when shutter speed is reduced, the HKDW-905R allows operators to produce creative pictures when shooting moving objects, through the intentional use of blurred images. The image-inversion function of the HKDW-905R board also allows the use of a variety of image-inverting lenses, the Anamorphic Lens Adaptor, and cinema lenses with 2/3-inch adaptors. *The slow-shutter function and the image-inversion function cannot be used simultaneously. The shutter speed can be adjusted to a 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 16-, 32-, or 64-frame period.
