Record mode display

Here you can see an example of the live preview image on the LCD just prior to taking a shot, note the composition bracket in the center of the frame. Various settings information is displayed along the top and bottom (in this case):

Top: Exposure mode (P), Image size / Quality, Frames remaining at current setting.
Middle: Macro focus mode, Shake warning.
Bottom: Shutter Speed, Aperture, Exposure compensation bar.

Half-pressing the shutter release causes the cameras autofocus and metering systems to lock, if the camera can't focus it will show
"! AF" in red on the LCD screen. The hand indicates potential blur due to shake (a slow exposure).

After fully depressing the shutter release a brief review is shown (this can be disabled). While the image is being written away a small indicator animated icon will be shown in the top right corner of the display. You can shoot while the image is being flushed, however you can't enter the menu or change camera settings.

Pressing the DISP button changes the live view, one press simply removes all overlaid information, two presses shows this useful 'thirds' overlay which is helpful when composing certain scenes (portraits for example). The 6900Z has a very useful live view magnify mode, press the small magnify button on the back of the camera (near the viewfinder) and the center of the frame will be magnified (until you press the button again). This is extremely useful for checking focus both auto and manual.
Pressing the INFO button (on the barrel side) displays this quick information panel which is a summary of the current settings (available by pressing MENU). Here's an example of movie mode. There are no image size, length or quality options. The 6900Z shoots at 320 x 240, 10 fps. Press the shutter release to start recording, press again to stop (or maximum of 160 seconds). Zooming is possible (digital only though).
Example of Shutter Priority mode (before half-pressing the shutter release). Note the shutter speed and aperture shown at the bottom of the display. Example of Aperture Priority mode (before half-pressing the shutter release). Note the shutter speed and aperture shown at the bottom of the display.
Example of Full Manual mode (before half-pressing the shutter release). Note the shutter speed and aperture shown at the bottom of the display along with the exposure meter indicating the under / over exposure of the current setting. Example of Scene Position exposure mode, each mode is shown along the bottom of the display and can be selected by rolling the command wheel.
Holding the SHIFT button (beside the LCD) offers two shortcut options, the first is to set the LCD brightness. The second to change file size / quality, press SHIFT and the flash button together. You can see above that the camera maintains the live view while you select the new image size / quality.

Play display

Switching to play mode immediately displays the last image taken. The 6900Z doesn't implement a 'rough image first' so it may take a second or two to display the image fully, an animated egg timer is shown while the image is loaded from the SmartMedia card. Press left / right arrows on the 4-way controller to move between images. I don't understand why Fujifilm didn't implement the command wheel for this purpose. Pressing the INFO button displays exposure information over the image, note the addition of a small histogram. It's a shame the histogram isn't implemented in record mode review (and made a little bigger too), it's a useful feature.
Pressing the zoom controller towards tele magnifies the displayed image. Pressing the OK button will create a new 'trimmed' image (lower resolution) from the current view. Pressing the DISP button while magnified allows you to scroll around the image using the 4-way controller.
Pressing the zoom controller towards wide switches to this 3 x 3 (9 image) thumbnail view, you navigate using the 4-way controller and can still carry out all play menu options (such as erase etc.) If, when scrolling through images you hold down the right arrow the camera will enter a 'fast forward' display mode (example above), let go when you reach the desired image. Again, this is useful but something which should have been implemented using the command wheel.
