∫Histogram
•A histogram is a graph that displays
brightness along the horizontal axis (black
to white) and the number of pixels at each
brightness level on the vertical axis.
•It allows the camera user to easily check
the way a picture is being exposed.
•It is very useful if manual adjustments of
the lens aperture and shutter speed are
available, especially in those situations
where automatic exposure may be difficult
due to uneven lighting. Using the
histogram feature will allow you to get the
best performance from the camera.
AWhen the values are concentrated to
the left, the picture is under exposed.
BWhen the values in the histogram are
distributed evenly, the exposure is
adequate and the brightness is
well-balanced.
CWhen the values are concentrated to
the right, the picture is over exposed.
Example of histogram

BProperly Exposed
COver Exposed
¢Histogram
•When the recorded picture and the
histogram do not match each other
under the following conditions, the
histogram is displayed in orange.
–When the flash is activated
–When the flash is closed
1When the brightness of the screen is
not correctly displayed in dark places
2When the exposure is not
adequately adjusted
•The histogram does not appear when in
motion picture mode [ ], during multi
playback and playback zoom.
•The histogram in the recording mode is an
approximation.
•The histogram in recording and playback
may not match each other.
•The histogram in the camera does not
match the one displayed in image editing
software used with a PC, etc.
•Check white saturated areas with the
highlight display in the auto review
function or the review function. (P29)
