Exposure (Shutter Speed And Aperture) - FujiFilm FinePix S20 Pro Owner's Manual

STILL PHOTOGRAPHY FUNCTIONS
EXPOSURE ( SHUTTER SPEED AND APERTURE )
Exposure refers to the light that hits the CCD or the total amount of captured light and determines
the brightness of the image.
The exposure is determined by the combination of aperture and shutter speed. In AE (automatic
exposure), the camera determines the correct exposure, allowing for factors such as the brightness
of the subject and the sensitivity setting.

When you cannot get the correct exposure
AE lock: Determines and fixes the exposure at a target level. Use the following procedure to take a
picture using AE lock:
Press the "AE-L" button (sets and locks the
exposure). ➡ Press the Shutter button down
halfway (sets and fixes the focus). ➡ Press
the Shutter button down fully (takes the
picture).
Exposure compensation:
This function uses the exposure level set by
the AE function as a reference (0) and then brightens (+) or darkens (–) the image. By
selecting Auto bracketing, you can shoot 3 frames, one underexposed (–), one at the
reference exposure (0) and one overexposed (+).
Shutter speed
When shooting a moving subject, you can either "freeze the motion" or "capture the sense of
movement" by adjusting the shutter speed.
Fast
Aperture
By adjusting the aperture, you can change the depth of focus (depth of field).

The graph at left shows the way the aperture and shutter speed settings can
be changed while maintaining the same exposure level.
h When the aperture is decreased by one step, the shutter speed also
decreases by one step (the dot moves upper left).
h When the aperture is increased by one step, the shutter speed also
increases by one step (the dot moves lower right).
h Combinations that result in the shutter speed or aperture being outside the
available range of settings cannot be selected (white dots).
h In the " ", " " and " " photography modes, it is easy to select different
settings along this line.
h Selecting settings that run parallel to this line by adjusting the brightness of
the photographed image is referred to as exposure compensation.
