CONTROLS

TOP PANEL CONTROLS

Nikon D40 Top Panel Controls.

Exposure Mode Selector Knob

(shown above.) Spin it to select among P, S, A and M exposure modes. I ignore the green AUTO (as shown above) and the other convenience modes (flower, lady in hat, etc.).

Many of the menu options are shown only after you select the FULL MENUS option in the Setup Menu (page 35) and are often deactivated in anything except the P, S, A and M exposure modes.

P: Program Automatic Exposure Mode

I use "P" for program auto exposure. In this mode the camera chooses the f/stop and shutter speed for you.

It's easy to get to any aperture or shutter speed you prefer in this mode: simply move the rear dial to shift them. This selects alternate combinations of f/stops and shutter speeds (page 88) which

give the same exposure. Nikon calls this "Program Shift." A *P symbol appears on the bottom left of the viewfinder, to the left of the shutter speed.
