Effects Mode
Select Nikon digital SLR cameras feature special effects that can be used when recording still images or D-movies. For example, on the D5100, they can be found by selecting Effects on the camera's mode dial, and scrolling through the various effects via the command dial. You can preview which effect will be used when the camera's menu is set for the Classic or Graphic mode or when the D5100 is set for Live View operation. These special Effects work with JPEG files (if JPEG + NEF is chosen; or NEF however, only JPEG files are recorded).
