By using the Nikon D3300’s Release mode setting, you tell the camera whether to capture a single image each time you press the shutter button; to record a burst of photos as long as you hold down the shutter button; or to use Self-Timer mode, which delays the image capture until a few seconds after you press the shutter button.
You also get two options related to wireless remote control shooting and Quiet Shutter mode, which dampens the normal shutter-release sounds.
Why Release mode? It’s short for shutter-release mode. Pressing the shutter button tells the camera to release the shutter — an internal light-control mechanism — so that light can strike the image sensor and expose the image. Your choice of Release mode determines when and how that action occurs.
On the Information screen and Live View display, the current Release mode is indicated by the icons labeled in the figure. Note that the Live View screen in the figure shows the default data-display mode; if your screen shows a different assortment of data, press the Info button to cycle through the available display modes.
To adjust the Release mode setting, press the Release mode button, labeled in the figure, to display the selection screen shown on the monitor in the figure. Use the Multi Selector to highlight the setting you want to use and then press OK.
