Taking Photographs—Exposur
e
A: Aperture-Priority Auto
In aperture-priority auto, you choose the aperture while the camera au to -
mat i cal ly selects the shut ter speed that will produce the optimal exposure.
Small apertures (high f/-numbers) increase depth of fi eld, bringing both the
main subject and back ground into focus. Large apertures (low f/-num bers)
soften background details and let more light into the camera, increasing the
range of the fl ash and making photographs less susceptible to blurring.
To take pho to graphs in aperture-priority auto:
1 Press the button and rotate the main com-
mand dial until A is displayed in the viewfi nder
and top control panel.
2 Rotate the sub-com mand dial to choose the
de sired aperture.
3 Frame a photograph, focus, and shoot.
