Chroma, Area and Y level, plus a level adjust-
ment for softening skin tones, enable the
operator to achieve the most natural results.
Iris: The Iris Limit function can be set from
OFF to f/9.5. With the Canon 20x HD Video
Zoom Lens, the multi-level iris control
becomes available beyond the iris diffraction
f-number (f/9.5) all the way up to closed
(Iris Limit set to OFF). It can also be controlled
using LANC with the optional Canon ZR-2000.
Gain: Gain val-
ues can be fine
tuned in 0.5 dB
increments from
0 to +18 dB,
enabling the
operator to opti-
mise sensitivity
when shooting
in low light.
Additionally,
-3 dB and +36 dB
settings are available. The gain limit can
also be set during AGC, so that levels can
be judiciously adjusted, for example, when
shooting in the dark. While selecting a WB
or Gain setting, a new function ensures
shockless transitions.
Colour Correction: Colour Correction enables
the user to control R or B gain (-6 to +6)
in 16 areas as well as selected colours set
at the Hue, Chroma, Area, Y level while
shooting. Selective Noise Reduction lets
the user apply noise reduction to targeted
colour areas. The Menu selection bar uses
numbers to simplify EVF Setup, Skin
Detail and Colour Correction.
White Balance: The camera's high-precision,
through-the-lens, 128-segment white
balance features an increased adjustment
range of 2,000–15,000° Kelvin. White
subjects are captured white, even in difficult
lighting situations, such as candle light.
Several automatic modes also deliver accu-
rate colour in a variety of shooting situations.
Auto — The camera accurately and
automatically adjusts white balance.
Outdoor — White balance is adjusted for
bright sunlight (5,600° Kelvin).
Indoor — White balance is optimised for
incandescent lighting
(3,200° Kelvin).
Colour Temperature —
White balance can be
selected in 100° Kelvin
intervals in a range of
2,000–15,000° Kelvin.
Program AE
Modes
The camcorder's 7 pre-programmed Auto
Exposure modes cover a wide variety of
shooting situations. Ideal settings produce
top-quality results quickly and easily. To
simplify operation, Manual Mode is located
next to OFF on the Power Dial.
Full Auto: The camera takes over for point-
and-shoot simplicity, setting focus, shutter
speed, aperture, gain, white balance and
AE program shift to achieve ideal results.
Auto: This mode offers all the convenience
of Easy Recording, but allows the operator
the option of manually changing the settings.
Shutter Priority: The user selects the shutter
speed and the camera automatically selects
the proper aperture for correct exposure.
Aperture Priority: The user selects the
lens aperture, and the camera automati -
cally sets the proper shutter speed for
correct exposure.
Manual: This mode allows the user to
select aperture and shutter speed in any
combination. The viewfinder indicates the
relation of selected combinations to the
exposure as metered by the camera.
Spotlight: Perfect for an automatic solu -
tion to a typically tricky situation: when the
subject is illuminated by a concentrated light
source (such as a spotlight) and the back-
ground is relatively dark, this mode auto-
matically adjusts exposure to compensate.
Night: As ambient light levels begin to fall,
the camera uses slower shutter speeds to
achieve optimal image quality.
Viewfinder
The XL H1S and XL H1A are equipped with
a 2.4-inch widescreen combination EVF/
LCD monitor (approx. 215,000 dots) for a
clear, high-resolution image. The XH G1S
and XH A1S provide both an EVF (approx,
269,000 dots) and a separate flip-out 2.8-
inch LCD monitor (approx. 207,000 dots).
Numerous viewing functions are provided
to maximise convenience and boost the
quality of capture. Aspect guides provide
industry-standard picture formats, while
Histogram and EXIF displays offer real-time
brightness information for highly accurate
adjustments. The operator can choose to
display up to 8 characters of the Custom
Preset name and the SDI bit map display
may be turned on or off. All viewfinder
display information can be removed to
leave a clear, unobstructed viewing area.
A Magnifying function (operable with the
Photo button) enlarges the viewfinder
image, making it easier to perform fine
image adjustments. Remaining memory is
displayed when using Focus Enhancements
External Hard Disk Recorders.
Enhanced Operation
Versatility and convenience are hallmarks
of Canon professional camcorders. Still
images can be "grabbed" from footage
either while shooting or during playback.
These images can be saved on the memory
card for subsequent transfer. The camera's
power LED illuminates green when the
camera is powered up and ready. Playback
mode preserves the letterbox format,
allowing an accurately proportioned view
of captured footage. A default write and
protect function prevents accidental deletion.
Marker colours may be specified at the user's
discretion. The camcorders also support
9 languages: German, English, Spanish,
French, Italian, Polish, Russian, Chinese
(simplified) and Japanese.
