Panasonic NV-GS500 Operating Instructions - Page 40

Record mode Manual shutter speed adjustment ≥Avoid recording under fluorescent light, mercury light or sodium light because the colour and brightness of the playback image may change. ≥If you increase the shutter speed manually, the sensitivity lowers and accordingly the gain value increases automatically, which may increase the noises on the screen. ≥You may see vertical lines of light in the playback image of a brightly shining subject or highly reflective subject, but this is not a malfunction. ≥During normal playback, image movement may not look smooth. ≥When recording in the extremely bright place, the colour of the screen may change or flickers. If so adjust the shutter speed manually to 1/50 or 1/100. Manual iris/gain adjustment ≥Set the shutter speed before setting the aperture (iris/gain) when manually adjusting both settings. ≥If the value does not become "OPEN", you cannot adjust the gain value. ≥If the gain value is increased, the noise on the screen increases. ≥Depending on the zoom magnification, there are iris values that are not displayed. ª Shutter speed range 1/50 to 1/8000 seconds: Tape Recording Mode 1/2 to 1/2000 seconds: Card Recording Mode The shutter speed closer to 1/8000 is faster. ª Iris/gain value range CLOSE (Closed), F16, ..., F1.7, OPEN (Opened: F1.6) 0dB, ..., 18dB Value closer to [CLOSE] darken the image. Value closer to [18dB] brighten the image. Values with dB are gain values. ª Card slow shutter mode ≥If the shutter speed is set to 1/2, 1/3, 1/6, or 1/12, then the card slow shutter mode will be activated. ≥If the power is off or the mode dial is operated, then the slow shutter mode will be cancelled. ≥In the slow shutter mode: ≥The white balance is fixed. ≥Focus in manually. ≥If the [AUTO/MANUAL/FOCUS] switch is set to [FOCUS], then the shutter speed will automatically be set to 1/50 and the subject is focused in on. After that the previous shutter speed will be restored. When the subject is focused on, [MF] flashes. MF ≥If the scene is low in brightness or contrast, the subject may not be focused in on. ≥While the movie camera is focusing on the subject, you cannot operate any control on it with the exception of [OFF/ON] switch, mode dial, [AUTO/MANUAL/FOCUS] switch and [POWER LCD] button. 40 VQT0T47
