settings you can use to help you
capture the level of highlight and
shadow detail you want. In addition,
there’s a D-Range Optimizer bracketing
function that records images at three
different optimization levels to allow
best-shot selection.
D-Range Optimizer for rich tone
gradations in high-contrast light
When photographing scenes that
contain extremes of light and shadow,
it can be difficult to capture the full
range of tonal gradations that the
human eye can see. But with the
900’s D-Range Optimizer function,
the camera analyzes the scene for
you, and automatically adjusts
gradation reproduction parameters to
assure optimum exposure balance,
with richer highlight and shadow detail.
In Standard mode, the D-Range
Optimizer analyzes the overall image
before performing the optimization,
and in Advanced mode,
5 it analyzes
each area of the composition
separately. On the 900, improved
algorithms provide even better
performance, with a choice of
Advanced Auto and Advanced Level
3 high-precision metering modes
for greater shooting versatility
The 900 is equipped with a 40-segment
honeycomb-pattern metering sensor that
uses advanced algorithms to ensure
balanced exposures under a wide range
of lighting conditions. A convenient 3-way
switch on the back of the camera allows
you to choose between 40-segment
honeycomb-pattern metering, center-
weighted metering, or spot metering
according to your shooting needs.
Versatile white balance settings
for superior color in any light
The 900’s versatile range of white
balance settings can be instantly
accessed via a button on the top of
the camera. In addition to Auto white
balance mode there are user-tunable
presets for Daylight, Shade, Cloudy,
Tungsten, Fluorescent, and Flash
lighting, as well as an adjustable
Color Temperature mode and three
user-configurable Custom modes.
White balance bracketing, which
records a single frame at three
different white balance settings, can
also be set via the Drive mode menu
for easy best-shot selection.
Exposure effect simulation
Another advanced function introduced
for the first time on the 900 is
Intelligent Preview. Using this function,
you can simulate the effect of various
D-Range Optimizer, exposure
compensation, and white balance
settings, and display the result on the
LCD monitor without actually taking a
picture. It’s a great way to fine-tune
image adjustments in advance when
working with a tripod and complex
shooting setups.
Quick access to exposure modes.
Standard exposure modes accessible
from the top-mounted mode dial
include Program Auto, Aperture
priority, Shutter-speed priority,
Manual, and Auto.
Exposure bracketing up to ±2EV
for secure “best-shot” capture
Exposure bracketing can be set via
the Drive mode button to enable best-
shot selection from a series of images.
In keeping with the 900’s high
performance standards, the range of
selectable options includes 3-frame or
5-frame bracketing in 0.3EV, 0.5EV,
or 0.7EV increments, as well as new
3-frame ±2EV bracketing that makes
it easy to create stunningly realistic
high dynamic range composite images.
