Shooting Functions

Dynamic range is the ratio that indicates the light level expressed by the
CMOS sensor pixels from bright areas to dark areas. The larger it is, the
better the whole range from dark to bright areas will appear in the picture.
By expanding the dynamic range, you can expand the light level
expressed by the CMOS sensor pixels, making it more difficult for an
overexposed area to occur in the image.
To expand the dynamic range, use [D-Range Setting] in the [A Rec.
Mode 1] menu. (p.199)
Expanding the Dynamic Range
Noise Reduction
When you use a digital camera to shoot with a long exposure or high
sensitivity setting, image noise (image roughness or unevenness)
becomes noticeable.
You can reduce image noise by using Noise Reduction. Images shot
with Noise Reduction take longer to save.
Slow Shutter Speed NR
Reduces noise during long exposures.
Set in [18. Slow Shutter Speed NR] in the [A Custom Setting 3] menu
(p.86).
High-ISO Noise Reduction
Reduces noise at high sensitivity (ISO) settings.
Select [Off], [Low], [Medium], or [High] for [19. High-ISO Noise
Reduction] in the [A Custom Setting 3] menu (p.86). You can set the
sensitivity at which to start noise reduction by setting [20. High-ISO
NR Start Level] in the [A Custom Setting 3] menu (p.86).
On
The camera determines the conditions such as the shutter speed,
sensitivity, and internal temperature, and automatically reduces
noise as necessary.
Off
Reduces noise only when the exposure mode is set to p and the
shutter remains open for 30 seconds or more.
