Taking Pictures Using the Histogram A histogram is a graph showing the brightness distribution of the image, with the brightness on the horizontal axis (darkest at the left and brightest at the right) and the number of pixels on the vertical axis. The shape of the histogram tells you whether the exposure of the image is correct or not. If the exposure is correct, the graph peaks in the middle. If the image is too dark, the peak is on the left side, and if it is too bright, the peak is on the right side. With the OptioWP, you can check the brightness distribution of the image by displaying it on the LCD monitor as well as by referring to the histogram. Bright portions (where the image is so bright that it is totally white) blink red on the LCD monitor and dark portions (where the image 4 is so dark that it is totally black) blink yellow.

Taking Pictures
A histogram is a graph showing the brightness distribution of the image,
with the brightness on the horizontal axis (darkest at the left and
brightest at the right) and the number of pixels on the vertical axis.
The shape of the histogram tells you whether the exposure of the image
is correct or not. If the exposure is correct, the graph peaks in the middle.
If the image is too dark, the peak is on the left side, and if it is too bright,
the peak is on the right side.
With the OptioWP, you can check the brightness distribution of the
image by displaying it on the LCD monitor as well as by referring to the
histogram. Bright portions (where the image is so bright that it is totally
white) blink red on the LCD monitor and dark portions (where the image
is so dark that it is totally black) blink yellow. (
