High ISO NR
Photographs taken at high ISO sensitivities can be processed to reduce "noise" (randomly-spaced
bright pixels).
Option
[High]
Reduce noise in photographs taken at all ISO sensitivities. The higher the sensitivity,
[Normal] the greater the effect. Choose the amount of noise reduction performed from (in order
from high to low) [High], [Normal], and [Low].
[Low]
Noise reduction is performed only as required. The amount of noise reduction
[Off]
performed is always lower than when [Low] is selected.
