Nikon 27637, J3 White, 27658, 27649, 27638 Long Exposure NR, Optical VR, 128, AVibration Reduction

Long Exposure NR

Photographs taken at slow shutter speeds are automatically pro- cessed to reduce “noise” (bright spots, randomly-spaced bright pixels, or fog), slightly increasing recording times. Selecting On increases the amount of noise reduction performed at shutter speeds slower than 1 s and increases the time required to record images by roughly 1.5 to 2 times. During processing, a warning will be displayed 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.

Optical VR

This option is available with 1 NIKKOR lenses that support vibra- tion reduction (VR). The options available vary with the type of lens: Normal/Active/Off for lenses that support active vibration reduction and On/Off for other VR lenses. Choose Active, Nor- mal, or On to reduce the effects of vibration; choose Active when shooting from a moving vehicle or while walking or for other forms of strong camera shake, Normal for the relatively mild camera shake that occurs while standing still.

AVibration Reduction

When the camera is panned, vibration reduction applies only to motion that is not part of the pan (if the camera is panned horizontally, for example, vibration reduction will be applied only to vertical shake), making it much easier to pan the camera smoothly in a wide arc. The composition may appear to change after the shutter is released, but this does not indicate a malfunction.
