To choose aperture, rotate the command dial.

Command dial

 

In aperture-priority auto, you choose the aperture while the

#

camera automatically selects the shutter speed that will produce

 

the optimal exposure. Large apertures (low f-numbers) increase

 

flash range and reduce depth of field, blurring objects behind and

 

in front of the main subject. Small apertures (high f-numbers)

 

increase depth of field, bringing out details in the background and

 

foreground. Short field depths are generally used in portraits to

 

blur background details, long field depths in landscape

 

photographs to bring the foreground and background into focus.

 

Large aperture (f/5.6)
