Play mode display

Just like previous Coolpix digital cameras (and several other manufacturers cameras) the 8400 uses a 'rough image' thumbnail to speed the initial display of the image in play mode, this is replaced by a finer detail image once the image data has been loaded from the Compact Flash card. Press the display button to switch to a clean view with no overlaid information. Press again to return to the basic information overlay shown on the left.

Image information pages

In addition to the above display mode there are also six other information "pages", these are accessed by simply turning the command dial, one click per page.

1: Camera name, Firmware, Metering mode, Exposure mode, Shutter speed, Aperture 2: Exposure compensation, Focal length (native), Focus mode, Flash mode, Image adjustment, ISO sensitivity
3: White balance, Saturation, Sharpness, Digital Zoom, Lens Converter, File Size 4: Thumbnail view with overexposed areas highlighted (blinking), Filename, Basic exposure information and an exposure histogram
5: Filename, Basic exposure information, AF area selected for focus. Note that the image is sharpened in the same way as focus confirmation in record mode  

Image magnification / Thumbnail display

The camera provides playback magnification up to 10.0x (more than previous models). Magnification levels are selectable from 1.2x to 10.0x, use the zoom controller to magnify the image, press the SET button to return to normal "full size" image. Once magnified the image can be scrolled using the 4-way direction pad. Press the shutter release to create a cropped copy of the current view (clip).
Two thumbnail views are available, a 2 x 2 (4 image) and 3 x 3 (9 image) view. Simply push the zoom lever towards wide angle to step 'out' to each view. With a thumbnail view active you use the 4-way direction pad to navigate around the thumbs, turn the command wheel to scroll through "pages" of thumbnails (4 or 9 at a time).


Several of the Play mode menu options require you to select images, this is carried out using this three thumbnail row view. Use the the left and right arrows on the multi selector to move through the selection and up or down to select/deselect. Press and hold the audio record (exposure compensation) button to attach an audio clip of up to 20 seconds to the current image.
This is the new Quick playback zoom, press the SET button on the 4-way controller to quickly jump to a 3x magnification with a grid style indicator of position. Pressing the erase button (trash can icon) displays this confirmation dialog.
