Release mode controls what happens when the shutter is released.

 Single frame
The camera takes one photograph each time the shutter-release button is pressed.

 Continuous low speed
While shutter-release button is held down, camera takes photographs at frame rate selected for Custom Setting d1 (CL mode shooting speed).

 Continuous high speed
While shutter-release button is held down, camera takes photographs at frame rate given in “Power Source and Frame Rate”. Use for active subjects.

Maximum frame rate (fps): 7
Power source: Camera with EN-EL15a battery or with EP-5B power connector and EH-5c/EH-5b AC adapter

 Quiet shutter-release
As for single frame, except that the mirror does not click back into place while the shutter-release button is fully pressed, allowing the user to control the timing of the click made by the mirror, which is also quieter than in single frame mode. In addition, a beep does not sound regardless of the setting selected for Beep options > Beep on/off in the setup menu.
 
 QC (quiet continuous) shutter-release
While shutter-release button is held down, camera records up to 3 frames per second. Camera noise is reduced.

 Self-timer
Take pictures with the self-timer.
 
 Mirror up
Choose this mode to minimize camera shake in telephoto or close-up photography or in other situations in which the slightest camera movement can result in blurred photographs.
