User manual SONY CCD-TR94

[. . . ] You will soon be producing home video that you can enjoy for years to come. To prevent fire or shock hazard, do not expose the unit to rain or moisture. 7 Getting started Charging and installing the battery pack . 42 Wiping away a still picture (CCD-TR94 only) . [. . . ] You can select from the following 15 values: F1. About the depth of focus field The depth of focus field is the in-focus range measured from the distance behind a subject to the distance in front. The depth of focus field can vary with the aperture value and the focal length. Zooming in telephoto position offers a smaller depth of focus field while the depth of focus field in wide-angle position is greater. You can select the shutter speed between 1/50 and 1/10000. When you select a faster shutter speed, movement appears clearer with less shaking. The aperture value is automatically adjusted according to the selected shutter speed to maintain appropriate exposure. This mode is most effective when you shoot the picture with high-speed movement. Note that the shutter speed is indicated in the viewfinder as, for example, "100" for 1/100 shutter speed. You can select from the following 16 speeds: 1/50, 1/75, 1/100, 1/120, 1/150, 1/215, 1/300, 1/425, 1/600, 1/1000, 1/1250, 1/1750, 1/2500, 1/3500, 1/6000, 1/10000. For a faster shutter speed, select a larger value indicator in the viewfinder. Note on gain level When you select a gain level that is too high, the picture may be distorted. If you want to record a dark picture brightly, or represent the movement of the subject lively, set the shutter speed to 1/25, 1/12, 1/6 or 1/3 (Slow shutter). Press SHUTTER SPEED repeatedly until the shutter speed value indicator disappears in the viewfinder. When recording with slow shutter function You cannot use flash motion, overlap, wipe, still or luminauncekey function. When you shoot in manual adjustment mode, we recommend you to keep the exposure fixed to make a clear picture. This section shows you what the exposure is and how to adjust each item with the exposure fixed. Total EV = EV from aperture control + EV from shutter speed control + EV from gain control The total exposure value can be varied or maintained at a constant level by controlling the aperture, gain and shutter speed. Use the following graph to select the setting. [a] Vertical axis: Aperture value (F value) [b] Horizontal axis: Shutter speed (per second) [c] Diagonal axis: Gain level (dB) When the aperture value is F11, the shutter speed is 1/50, and the gain level is 0 dB, adjust the aperture value manually to F5. If you change the aperture value from F11 to F5. 6 in the above example, the exposure from aperture control becomes brighter by +2 EV.
