HV20/30 QUICK REFERENCE CARD
First,
read the Instruction Manual. Even if you skim the rest, slow down and read pp.45-52.
RECOMMENDED BASIC SETTINGS FOR NORMAL SHOOTING
IMAGE EFFECT: NEUTRAL, LOW SHARPENING, SOFT SKIN DETAIL or CUSTOM with most values lowered from their defaults are preferable to NONE or VIVID.
AUTO-FOCUS: Normal (through the lens)
DIGITAL ZOOM: OFF
ZOOM SPEED: VARIABLE
ASSIST FUNCTION: ZEBRA 100% (only deliberately overexposed areas such as bright lights or reflections should show zebras)
HDV 60i or HDV PF24: As dictated by project. SD modes are not recommended.
For shallowest depth of field, the camera should be placed far from the subject and zoomed in while using the widest possible aperture. In bright conditions ND filters or variable polarizers may be used to lower exposure. However underexposure must be avoided because the camera may add as much as 27dB of gain and/or drop to 360° shutter with no indication given to the operator. Similarly in bright conditions an internal variable ND filter is added automatically which holds the aperture at f/5.6 for 11 clicks of exposure adjustment. The HV loves light and requires at least 55 footcandles/600 lux (1000 watts tungsten at 12 feet) to achieve f/1.8 0dB gain.
SEMI-AUTOMATIC SHOOTING
CINE mode is preferred because it allows IMAGE EFFECT and WHITE BALANCE to be set and because it flattens contrast and preserves more highlight and shadow detail than other modes. However because it will raise shutter speed above f/8 and may add gain or drop to half shutter in low light, checking and locking exposure is required when using CINE mode in very bright or low light or when wide apertures are desired. Set light meters at ISO 100.
The following modes never add gain, but disable manual IMAGE EFFECT and WB settings and may drop to slow shutter:
SUNSET,
SPOTLIGHT and
PORTRAIT modes.
(MOSTLY) MANUAL SHOOTING
Set Exposure program to “
Tv.” Select shutter speed (180° shutter = 1/60th for HDV 60i, 1/48th for HDV PF24). Press
FOCUS to select manual focus (
MF appears on screen). Press
FOCUS ASSIST in REC/PAUSE mode to magnify center of picture (cancels on recording). Preset or custom WB and IMAGE EFFECT may be used. Set light meters at ISO 80.
LOCKING EXPOSURE
Note that the HVx0 has no “exposure compensation” mode; exposure either remains locked where set or adjusts automatically. Likewise gain cannot be discovered or controlled directly: operators must verify that the camera adds no gain with either of the following procedures. Gain is never added except at f/2.8 and below. (See table 1).
Table 1 Available apertures with possible gain indicated in red.
TRY TRY AGAIN METHOD
Camera must be equipped with a MiniSD card. Zoom to desired framing. Half-press
PHOTO button, f/stop and shutter speed are briefly displayed on screen. Lock exposure (press
SET, scroll DOWN to EXP, scroll UP and press
SET to select, scroll LEFT/RIGHT to adjust). Half-press
PHOTO button again. Below f/3.2, if exposure increases (picture gets brighter) but f/stop stays the same, gain is being added. No more than one “click” of gain (approximately 7dB) is recommended, with none being preferable. Press
SET again to lock (blue exposure bar remains onscreen).
EXPOSURE TARGET (CELL PHONE) METHOD
Alternately, fill the frame with a source known to produce an exposure where the rightmost click of available adjustment (+11) is WFO f/1.8 with 0 gain (such as a blank cell-phone text message screen or sheet of paper held about six inches from the lens illuminated by the camera’s onboard LED light), lock exposure and adjust. Half-press
PHOTO button to verify f/stop and shutter speed. Press
SET again to lock (blue exposure bar remains onscreen).
