Nikon D3300 - Manual (Page 241)

221 D The Playback Menu: Managing Images
Choose whether pictures are automatically displayed in the
monitor immediately after shooting.
If On is selected, “tall” (portrait-orientation) pictures will be
automatically rotated for display in the monitor (pictures taken
with Off selected for Auto image rotation will still be displayed
in landscape orientation;
0 243). Note that because the camera
itself is already in the appropriate orientation during shooting,
images are not rotated automatically during image review.
