Pentax K-500 Operating Guide

efore Using Your Camera

When the image is underexposed, the part to the left is cut off

(underexposed portions with no detail) and when the image is

overexposed, the part to the right is cut off (overexposed portions

with no detail).

You can set whether to display the bright/dark area warning during capture

or playback mode.

Distribution of color intensity is displayed for each color in RGB Histogram

Display. If a color is partially cut off on one side, it indicates that the color

is under- or overexposed, that the light is very weak or strong in that color,

or that the white balance is incorrect.

Using the Histogram

A histogram shows the brightness

distribution of an image.

The horizontal axis represents

brightness (dark at the left and bright

at the right) and the vertical axis

represents the number of pixels.

The shape and the distribution of the

histogram before and after shooting

tell you whether the exposure level

and contrast are correct or not, and

let you decide if you need to adjust

the exposure and take a picture

again.
