For shooting subjects in low level lighting conditions. EVS (Enhanced Vertical definition System) Shutter speed currently selected in the Standard or ECS mode Improved vertical resolution. However, the sensitivity and dynamic range are reduced. 1) Only for the DSR-450WS/450WSP 2) Only for the DSR-450WS 3) The SLS mode can only be selected when the CCD scan mode (page 108) is set to I (interlace scan) (DSR-450WS/450WSP only). Notes • Whatever the operating mode of the electronic shutter, the sensitivity of the CCD decreases with increasing shutter speed. • When the automatic iris is used, the iris opens wider as the shutter speed increases, thus reducing the depth of field. • Under artificial light, particularly fluorescent or mercury lamps, the light intensity may appear to be constant, but the red, green, and blue intensities are actually changing in synchronization with the frequency of the power supply causing flicker. Using an electronic shutter under such lighting could make the flicker even worse. Color flicker is particularly likely to happen when the power supply frequency is 60 Hz. However, if the power frequency is 50 Hz, setting the shutter speed to 1/100 can reduce this flicker. • When a bright object is shot in EVS or ECS mode in such a manner that it fills the screen, the upper edge of the picture may have poor quality because of an inherent characteristic of CCDs. Before using EVS or ECS mode, check the shooting conditions. You can turn on or off the EVS mode on the SW STATUS page of the PAINT menu. To select the shutter mode and shutter speed Use the SHUTTER switch to select a shutter mode or a standard-mode shutter speed. To set the shutter speed in ECS or SLS mode, with the SHUTTER switch set to ON and the ECS or SLS mode selected, use the MENU knob for adjustment. You can use the SHT ENABLE page of the OPERATION menu to narrow the range of choice in advance, or to select in advance whether or not you use ECS/SLS mode. To set the shutter mode and standard mode shutter speed Once the shutter speed is selected, it is retained even when the camcorder is turned off. 1 Set VF DISP MODE to 2 or 3 on the VF DISP 1 page of the OPERATION menu.
