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.
Set in [17. Slow Shutter Speed NR] or [18. High-ISO Noise
Reduction] in the [A Custom Setting] menu.
Slow Shutter Speed NR
Auto: The camera determines the conditions such as the shutter
speed, sensitivity, and internal temperature, and automatically
reduces noise as necessary.
On: Reduces noise only when shooting at slow shutter speeds
(under 0.3 seconds).
High-ISO Noise Reduction
Select the level of noise reduction from [Off], [Weakest], [Weak], or
[Strong] when shooting with a high-sensitivity setting.
