Initial Set Up As I go through the menus, I set these away from their defaults: PLAYBACK MENU Display Mode Detailed photo info > check RGB histogram and Data > DONE > OK. Transition effects > OFF > DONE > OK. By default, there are some time-wasting animations as you move among your photos Be sure to select DONE and click OK, otherwise your Display Mode preferences won't be saved.
If I'm photographing something more difficult, like moving kids or subject behind other things, I set [ 3D ] > OK. Now you select an AF point with the big rear control, and if the subject moves, the D3100 moves the AF point to track the motion of either the camera or your subject! Movie Settings By default, the D3100 makes large 1080/24p HD files.
By setting this to ON, the D3100 numbers files up to DSC_9999.JPG, and only then does it repeat. This prevents too much file name duplication on your hard drive, or on your online galleries.

Press < i > to get back to the picture on the screen. If you leave the focus at its default, the D3100 will focus a movie only as you hold the shutter button, and leave it fixed the rest of the time.
Need help?
Do you have a question about the D3100 and is the answer not in the manual?
