Slow Shutter Option Board for the HDW730S series camcorders powerfully enhances the operational and creative versatility of the HDW730S camcorder in both ENG and EFP applications. With the HKDW-705 equipped, the HDW730S 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-705 allows operators to produce creative pictures when shooting a moving object with the intentional use of blurred images. *The shutter speed can be adjusted to a 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 16-, 32-, or 64-frame period.
