Nikon D3X Operation

Nikon D3X Operation

Like other Nikon DSLRs, the user interface on the Nikon D3X is straightforward and simple to use, and almost identical to that of the D3. The LCD menu is a six-tab system that divides up functions between Playback, Shooting, Custom Settings, Setup, Retouch and My Menu. While many of the camera's options can be accessed via the excellent "plain English" menu system, all the most common shooting controls are available via the camera's external buttons and knobs. You can also program the operation of some of the buttons, to configure the camera for your particular shooting requirements. Nikon makes a big deal of their digital SLR's "cameraness," defined as how well/easily they function as cameras, and the D3X embodies that philosophy.

Nikon D3X Top Panel LCD

As with most higher-end Nikon DSLRs, the D3X's top-panel data readout LCD communicates a lot of information about current camera settings, and provides an interface for setting many camera functions, when used in conjunction with the various buttons and Command Dials. You can also use the main LCD to adjust many of the same settings, but using the top LCD saves power and can be more convenient when the camera is below eye level. The illustrations below show the meaning of the various icons and readouts in this display.

Nikon D3X Rear Control Panel LCD

Like other Nikon professional models, the Nikon D3X also has a rear Control Panel LCD. It is identical to the D3's. The illustrations below show the meaning of the various icons and readouts in this display mode.

Nikon D3X Main LCD

Shooting Information
Like other more recent Nikon digital SLRs, the D3X has the ability to display shooting info and settings on the rear LCD. The rear LCD is larger and in color (with selectable color scheme), so some prefer to use it over the top LCD, at the expense of battery life. It's nice that Nikon gives you the choice.

The illustrations below show the meaning of the various icons and readouts in this display mode. Compared to the D3, the D3X adds Copyright Information and Vignette Control indicators.

Nikon D3X Virtual Horizon
A really neat feature of the D3X (as well as the D3 and D700) is the virtual horizon gauge. It uses sensors in the body to detect the orientation of the camera and display a virtual horizon, similar to an aircraft instrument. This is useful for critical alignment of subjects such as buildings, the horizon, etc. With the use of the FUNC button, the electronic analog scales in the viewfinder can also display the amount of tilt, so that you don't need to take your eye off the subject to check the camera angle. Pressing the "info" button allows you to overlay the virtual horizon in Live View mode (as shown in the screenshot to the right.)

Nikon D3X Playback mode
Playback mode is entered by pressing the playback button on the top left corner of the back panel. The D3X's playback mode provides a great deal of information about your pictures after you've shot them. A variety of playback displays can be cycled through using the up/down arrows on the multi-selector, including showing the image with file information (with optional highlight warning and focus point display), RGB histogram, three screens with overlaid shooting and image parameter information (an additional GPS info screen is available when a GPS device was used when the image was captured), and an overview display with basic shooting data and luminance histogram. The screenshot animation at right shows the sequence when the down arrow is used to cycle through the available screens. And if you find this amount of information overwhelming, you can add or remove the displays as you see fit.

As you'd expect, the Nikon D3X offers a comprehensive RGB histogram display mode. Histogram displays are common on professional digital cameras (and many amateur models now), regarded as almost mandatory by many pros for evaluating exposure levels. A histogram is simply a graph of how many pixels there are in the image at each brightness level. The brightness is the horizontal axis, running from black at the left to white at the right. The height of the graph shows the relative number of pixels having each brightness level. This sort of display is very handy for determining under- or overexposure. Ideally, the histogram would stretch across the entire width of the display, using the full range of brightness values available. An underexposed image will have a histogram with all the data lumped on the left-hand side, with nothing reaching all the way to the right. Likewise, an overexposed image will have all the data lumped on the right hand side. Clipped highlights are shown by blinking any highlights that are saturated in any of the color channels. It does this by taking the nearly-white areas on the LCD and toggling them between white and black. Highlights can also be displayed separately for each color channel by selecting R, G, or B in this display.

Of course the Nikon D3X also lets you zoom out to quickly find and select images, or magnify them for closer inspection on its gorgeous 3-inch, 922K pixel LCD. You have the normal 4- or 9-image thumbnail displays available by pressing the thumbnail/zoom out button, and you can magnify them up to approximately 27x for large, 20x for medium and 13x for small images, using the zoom-in button. Once magnified, you can scroll around the image using the multi-selector to examine critical detail and framing. You can also program the multi-selector center button to automatically zoom in on the active focus point with a preset the initial zoom setting (low, medium, or high), to make focus verification faster and more convenient.

To return the Nikon D3X to shooting mode, simply press the playback button again, or half-press the shutter button.
