nHistogram
•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.
•When the values are concentrated to the left A, the picture is under exposed. Pictures that are mostly black, such as night scenery, forms this type of histogram.
•When the values in the histogram are distributed evenly B, the exposure is adequate and the brightness is well- balanced.
•When the values are concentrated to the right C, the picture is over exposed. Pictures that are mostly white, forms this type of histogram.
Example of 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 correct in dark places
2When the exposure is not adequately adjusted
•The histogram does not appear when in motion picture mode [i], 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 this 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. (P27)
