Marking pictures makes them easier to view and organize. The D6 lets you quickly mark pictures with flick gestures.
The D6 supports the following three types of marking:
Use Custom Setting f12 [Full-frame playback flicks] > [Flick up] or [Flick down] to choose the operation performed by flicking a finger up or down over the display during fullframe playback:
When [Rating], [Select to send (wired LAN/WT)], or [Protect] is selected, you can flick once in the chosen direction to add the selected marking and again in the same direction to remove it.
