∫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.
A When the values are concentrated to the left, the picture is under exposed.
B When the values in the histogram are distributed evenly, the exposure is adequate and the brightness is
C When the values are concentrated to the right, the picture is over exposed.

• When you take pictures with the flash or in dark places, the histogram is displayed in orange because the recorded picture and the histogram do not match each other.
• The histogram does not appear when in simple mode [
], 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 picture editing software used with a PC, etc.
