If you are using the camera for the first time, read this section. Histogram When Histogram is on, a histogram appears in the lower right corner on the picture display. A histogram is a graph indicating the number of pixels on the vertical axis and the brightness on the horizontal axis (from left to right, shadows (dark areas), midtones, and highlights (bright areas)). By using the histogram, you can determine the brightness of an image without being affected by the brightness around the picture display. This also helps you correct for areas that are overly bright or dark. If the histogram has only peaks on the right side, this picture is overexposed with too many pixels only for highlight sections. If the histogram has only peaks on the left side without anything else, this picture is underexposed with too many pixels only for shadow sections. Refer to this histogram when correcting the exposure. Note • The histogram displayed on the picture display is for reference only. • After taking a picture, you can correct its brightness and contrast by making adjustments to the histogram. (GP.129) • Depending on the shooting conditions (use of the flash, dark surrounding light, etc.), the exposure level indicated in the histogram may not correspond to the brightness of the shot image. • Exposure compensation has its limitation. It does not necessarily achieve the best possible result. • A histogram with peaks in the center may not necessarily provide the best result to suit your particular requirements. For example, an adjustment is required if you want to underexpose or overexpose the image. 64 • For information on how to correct the exposure compensation, see P.109.
