Chapter 2: Operations in DV mode Adjusting the shutter speed 1 Set the AUTO/MANUAL switch to MANUAL to select manual mode. (Page 54) 2 Press the SHUTTER button. • SHUTTER ON is enabled after switching to MANUAL mode from AUTO mode. The shutter speed switches between the standard (OFF) shutter speed and the shutter speed you have selected with the SPEED SEL -/+ button each time you press the button. • With artificial lighting and especially fluorescent lights and mercury-vapor lamps, the luminance changes in synchronization with the power line frequency. When this frequency is 50 Hz, mutual interference will occur between the camera- recorder's vertical sync frequency (approx. 60 Hz) and the lighting frequency (50 Hz). This means that the white balance may change periodically. Before shooting in areas with artificial lighting or adjusting the white balance, set the shutter speed as follows. Progressive mode Shutter speed 50 Hz 60 Hz OFF (60i) 1/100 1/60 (OFF) 30P 1/50 (OFF) 1/60 24P 1/50 (OFF) 1/60 • The shutter speed appears at the left of the screen during SHUTTER ON. 3 Press the SPEED SEL -/+ button to adjust the shutter speed while in SHUTTER ON mode. The shutter speed changes as per the following table. • As the shutter speed increases, camera sensitivity decreases. • With auto iris control, as the shutter speed increases, the aperture widens and the focal length decreases. • Because the focal time increases at slower shutter speeds, we recommend using a tripod. 65
