Long Exposure NR (Long Exposure Noise Reduction)

Gbutton ➜ Cshooting menu

If On is selected, photographs taken at shutter speeds slower than 1 s will be processed to reduce noise (bright spots, randomly-spaced bright pixels, or fog). The time required for processing roughly doubles; during processing,

“l m” will flash in the shutter speed/aperture displays and pictures

can not be taken (if the camera is turned off before processing is complete, the picture will be saved but noise reduction will not be performed). In continuous release mode, frame rates will slow and while photographs are being processed, the capacity of the memory buffer will drop. Long exposure noise reduction is not available during movie recording.

High ISO NR

Gbutton ➜ Cshooting menu

Photographs taken at high ISO sensitivities can be processed to reduce noise.

Option
