Understanding Dials and Buttons

Before we can explain how to use Coolpix 990, we need to know the locations and functions of various dials and buttons. We shall go through each button once with a brief explanation. However, for most of the cases, you really do not have to know the meaning and function of each button. So, please just browse the names and know the locations of these dials and buttons.

All control dials and buttons of this camera are either on the top panel or on the backpanel, except for a dial which is located in the front.

Controls on the Top Panel

The following shows the top panel of the camera.

The top panel has the mode dial and shutter release button (upper right), exposure mode selection button and exposure compensation button (middle), the command dial (lower right), and the control panel.

The Mode Dial and Shutter Release Button

The most frequently used dial on the top panel is the mode dial as shown in the following figure. The Mode Dial can be rotated and has four positions: OFF (turning off the camera), A-REC (automatic mode), M-REC (manual mode), and PLAY (playing back).

The Mode Dial and Shutter Release Button

The center of the mode dial is the Shutter Release Button. Pressing it halfway down activates focusing and exposure metering. Fully press this button to take a photograph.

The Mode Button

The MODE button (see the figure below) is the left one of the two buttons between the mode dial and the command dial.

The MODE Button

The MODE button (see the figure above) is used in the M-REC mode for setting exposure mode: P for the program mode which is the default, A for the aperture-priority mode, S for the shutter-priority mode, and M for the manual exposure mode.

To choose an exposure mode, first set the mode dial to M-REC. Then, hold the MODE button and at the same time turn the command dial. The lower-left corner of the LCD monitor and control panel will display P for the program mode, A for the aperture-priority mode, S for the shutter-priority mode, and M for the manual exposure mode.

The Exposure Compensation Button +/-

The +/- button (see the figure below) is the one next to the MODE button. See the figure below.

The +/- Button

By default, there is no exposure compensation. But, this compensation value can be changed in 1/3-stop increment or decrement. In the A-REC mode and M-REC mode, hold button +/- and at the same time turn the command dial changes the exposure compensation value. Turning the command dial clockwise increases exposure by 0.3-stop. Actual increments are 0.3, 0.7, 1.0, 1.3, 1.7 and 2.0. Turning the command dial counter-clockwise decreases exposure by -0.3-stop. Actual decrements are -0.3, -0.7, -1.0, -1.3, -1.7 and -2.0. Please see Exposure Compensation for the details.

Controls on the Back Panel

The controls on the back panel consist of two rows of buttons and a multi-selector as shown below. The top row has the Zooming button (right), the MONITOR button (left) and the MENU button (middle), while the bottom row has the image quality/size button QUAL (right), the flash/ISO button (middle), and the focus mode/delete button. The right edge of the back panel is the multi-selector (or rocker button). In the middle of the back panel is the LCD monitor.

The back panel

The Zooming Buttons

Near the upper-right corner of the back panel there are two buttons marked with W and T for zooming out (wide angle) and zooming in (telephoto), respectively. See the figure below.

The Zooming Buttons

The Monitor Buttons

In the upper-left corner of the back panel is the MONITOR button (see the figure below). This button controls the content to be displayed on the LCD monitor. It can be used in the A-REC mode, M-REC mode, and PLAY mode. However, the displayed information on the LCD monitor are different. By default, information of the current settings and playback settings are shown on the LCD monitor when the camera is turned on. Press MONITOR once to remove these information from the LCD monitor. Press it again to turn off the LCD monitor. Press it again to return to the default. When the LCD monitor is on, the camera focuses continuously, which consumes battery power. The LCD monitor consumes power as well. Therefore, if it is possible, you might consider to turn off the LCD monitor and use the viewfinder to save battery power.

The MONITOR Button

The Menu Button

In the middle of the top row of buttons on the back panel is the MENU button (see the figure below).

The MENU Button

Each of the three modes (i.e., A-REC, M-REC, and PLAY) has its own menu for setting some control information. Please refer to A-REC Menu, M-REC Menu, and PLAY Menu for the details.

The Flash Setting Button

The middle button of the bottom row is the Flash Setting Button (see figure below). This button is used for selecting various ways of using the built-in flash when the mode dial is in positions A-REC or M-REC.

The Flash Setting Button

There are five settings available: auto flash, flash off, auto flash with red-eye reduction, anytime flash, and slow synchronization. Click here to see the details.

Auto flash is the default when the camera is turned on. The setting changes each time the button is pressed, cycling through the different flash modes as follows:

The five flash settings

The Focus Setting Button

The focus setting button is the left-most one of the bottom row (see the figure below). It can be used in both A-REC mode and M-REC mode.

The Focus Setting Button

This button serves three different purposes. The first is to select a focus setting. The setting changes each time the button is pressed, cycling through the focus modes as follows. It starts with no icon, which means the camera uses autofocus. Press the button once to move to infinity setting so that the focus is fixed at infinity. The next mode is for close-up or macro mode. The last mode is Self-Timer, which is not part of the focus setting.

The focus settings

This button can also be used with the Command Dial (see below) for Manual Focus.

The Image Quality Button

The bottom row on the back panel of the camera has three buttons.

The QUAL Button

Button QUAL is the right-most one. Combined with the command dial it is used for selecting the image quality (i.e., image resolution). Please see Selecting Image Quality for the details. However, in the PLAY mode, this button has a different meaning. Please see Basic Playback for the details.

The Command Dial

The command dial locates in the upper-right (resp., lower-right) corner of the back (resp., top) panel. See the figure below.

The Command Dial

The command dial can be turned in both directions. Normally, it is used with other buttons such as the image quality button QUAL for selecting an image quality, the mode button MODE for selecting an exposure mode, and the +/- button for exposure compensation.

Multi-Selector

Just below the command dial is the multi-selector, also known as 4-way rocker button. See the figure below.

The Multi-Selector

The multi-selector is used for making a selection. There are four arrow heads, each of which indicates the movement in the corresponding direction. For example, the up and down arrows move a highlighted item up and down. In many cases, the right arrow is used for selecting the highlighted item. More will be discussed on other appropriate pages.
