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 well-balanced.

C When the values are concentrated to the right, the picture is over exposed.

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 image 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. (P28)
