Casio EX-Z30 manual Audio Recording Precautions, Using the Histogram

OTHER RECORDING FUNCTIONS

■Audio Recording Precautions

• Keep the microphone on the front of the camera pointed at the subject.

•Take care that you do not block the microphone with your fingers.

Microphone

•Good recording results are not possible when the camera is too far from the subject.

•Operating camera buttons during recording can cause button noise to be included in the audio.

•Pressing the power button or pressing [] (PLAY) stops recording and stores any audio recorded up to that point.

•You can also perform “after-recording” to add audio to a snapshot after recording it, and also change the audio recorded for an image. See page 109 for more information.

Using the Histogram

You can use the [DISP] button to display a histogram on the monitor screen. The histogram lets you check exposure conditions as you record images (page 25). You can also display the histogram of a recorded image in the PLAY mode.

Histogram

A histogram is a graph that represents the lightness of an image in terms of the number of pixels. The vertical axis indicates the number of pixels, while the horizontal axis indicates lightness. You can use the histogram to determine whether an image includes the shadowing (left side), mid tones (center), and highlighting (right) required to bring out sufficient image detail. If the histogram appears too lopsided for some reason, you can use EV shift (exposure compensation) to move it left or right in order to achieve better balance. Optimum exposure can be achieved by correcting exposure so the graph is as close to the center as possible.
