    Default Hv20/30/40 quick reference card

    This wasn't made by me but I felt it was worth posting for those few members that have a HV Camera. I hope you find it useful...

    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).

    Looks like a lot of good sense, Wil.
