Noise Reduction

Long Exposure NR: Photographs taken at shutter speeds slower than 8 s are processed to reduce noise. As the time required to process images to reduce noise after capture is roughly the same as shooting time (shutter speed), the time required until images are completely recorded increases accordingly.
High ISO NR: Photographs taken at ISO sensitivities of ISO 800 and higher are processed to reduce noise. “High”, “Normal” (default), “Low”, “Off”
At ISO sensitivities of Hi 0.3 and higher, a level of noise reduction lower than that achieved with a setting of "Low" is selected.
