By default the D50 will display a review of the image taken immediately after exposure. If you prefer this behavior can be disabled via custom function 5. The style of record review display depends on the last used play display mode, there are five different full size displays as well as two thumbnail index sizes. Note that the the function of the direction arrows of the 4-way controller have been switched since the D70 (and D70s), now left and right browse, up and down change display mode (much more logical).
Pressing the play button displays the last image shot (or the last image on the card). Press the 4-way controller up or down to change the display mode, there are five 'pages' of image information (including exposure details, histogram etc.). Press the 4-way controller left or right to browse through images, you can now also use the command dial to browse.
3: Detail - Image development, ISO sensitivity, White Balance, Image size, Image quality, Sharpness, Tone, Color Mode, Hue, Saturation, Comment
4: Highlights (note the blinking areas aren't necessarily completely overexposed but are 'near')
5: Histogram overlay
