Control depth of field,
depending
on how wide the aperture diaphragm is opened
An aperture diaphragm is a mechanism that cortro s the
amount of light entering a camera through the lens. By
adjusting the opening of the aperture, one can vary the depth
of the zone of in-focus elements. If the aperture IS wide open
(f/2 8, for example), the focused area becomes shallow,
result ng In greater blurring of images n front of and beh nd the
subject in focus. In contrast, f the aperture is small (f/22, for
example), the focused area becomes deep, resulting in greater
cla'ity of mages In front of and behind the subject in focus.
In a lens description - such as "EF-S60mm f/2.8
Macro USM - 1f/2.8" refers to the widest opening
of the lens aperture. When this "f" number is low, the
lens is considered "bright" or "fast." Bright lenses not
only capture beautifully blurred backgrounds but also
let you choose faster shutter speeds even In dark
places, reducing the risk
of undesired blurring
through "camero shake"

Exposure determines the overall brightness of photos.
Exposure compensat on allows ·he ohotographer to get' brighter' or "darker I results.
Automatic exposure is intended to create optimal photo
exposure. However, you can Intentionally change the
exposure level through exposure compensation. When
you wont to get brighter results, just set the exposure
level on the "plus" side, when you wont to get darker
results, set the exposure level to the minus" side.
If you use the AEB (automatic exposure bracketing)
function
on your calT'era one shot generates three
images with different exposure levels. Afterwords,
you can pick the best result from among these three
choices.
