Auto HDR
The Auto HDR function captures the
expanded detail of high dynamic
range photos. When you press the
shutter button, it instantly records
three frames at different exposures
and composites the best details
from each—in the highlights, mid-
tones and shadows—to create a
single image with wider dynamic
range than any single exposure
could possibly capture. The resulting
image is breathtaking and ideal for
post processing. You can select the
exposure range, making adjustments
in 1EV steps up to a maximum ±6EV.
No tripod is necessary when shooting
because subject movement is
precisely compensated for.

Multi Frame NR
The Multi Frame NR mode is extremely
effective at suppressing noise in dark,
challenging shooting situations.
Candlelit rooms, for example, can be
vividly captured without using a tripod
or flash. By seamlessly compositing
six images, this mode achieves noise
reduction equivalent to a 2-stop lower
shutter speed. Noise is lower than when
shooting normally at the same ISO
speed, and sensitivity equivalent to
ISO 51200 becomes possible when
shooting at the highest ISO speed.
Compatible with any ISO setting, the
Multi Frame NR mode can also be used
in combination with all P/A/S/M modes.

Dynamic Range Optimizer ( DRO )
In difficult lighting conditions, DRO
analyzes and corrects your image
in real time to expand its dynamic
range and achieve smoother, more
natural gradients with more detail in
the highlights and shadows. If a backlit
subject's face is dark, for example, it
recovers details hidden in the shadows
and delivers a naturally bright image.
DRO can be used effectively during
continuous shooting and lets you
choose the amount of correction up
to 5 steps.
Exposure compensation
and bracketing
Achieve just the right exposure by using
Exposure Compensation to increase
or decrease the exposure in 1/3 or 1/2
stop increments ( between -5 and +5
EV ) . Or use Auto Exposure Bracketing to
record three or five images at different
exposure values, compare the results
and choose the best one.
Exposure modes
The clearly labeled mode dial on top
of the a99 provides quick access to all
available exposure modes ( Program
Auto, Aperture priority, Shutter speed
priority, Manual exposure modes, Auto
mode and 8 Scene Selection modes ) .
