Canon 50D 1 2, 4

In this mode, you set the desired aperture and the camera sets the shutter

speed automatically to obtain the correct exposure suiting the subject

brightness. This is called aperture-priority AE. A higher f/number (smaller

aperture hole) will make more of the foreground and background fall within

acceptable focus. On the other hand, a lower f/number (larger aperture hole)

will make less of the foreground and background fall within acceptable focus.

*<f> stands for Aperture value (aperture opening).

1Set the Mode Dial to <f>.

2Set the desired aperture.

While looking at the LCD panel, turn

the <6> dial.

3Focus the subject.

Press the shutter button halfway.

XThe shutter speed is set

automatically.

4Check the viewfinder display and

shoot.

As long as the shutter speed is not

blinking, the exposure will be correct.
