Histogram - Panasonic Lumix DMC-FZ18 Operating Instructions Manual

Advanced (Recording pictures)
∫ Recording guide line
When you align the subject on the
horizontal and vertical guide lines or the
cross point of these lines, you can take
pictures with well-designed composition by
viewing the size, the slope and the balance
of the subject.
A [ ]: This is used when dividing the
entire screen into 3k3 for
taking pictures with a
well-balanced composition.
B [
]: This is used when you want to
position the subject at the
exact center of the screen.

∫ 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 you to easily check a picture's
exposure.
• 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 allows you to get the
maximum performance from your camera.
A When the values are concentrated on
the left, the picture is under exposed.
B When the values are distributed evenly,
the exposure is proper and the
brightness is well-balanced.
C When the values are concentrated on
the right, the picture is overexposed.
