Chapter 12: Taking Great Pictures
Microsoft Digital Image Standard User’s Manual
For portrait photography, a wide aperture helps to limit the focus. Your
subject’s face is clear and sharp, but objects in the background are blurred. But
if you’re taking a vacation photo of someone posing in front of a monument, a
narrow aperture might be in order. With the narrow aperture, both the person
and the monument can be in focus in the same photo.
Of course, adjusting the aperture also affects how much light is let into the
camera. But if a specific depth of field is important for your shot, you might
want to switch to manual mode, set the aperture, and then set the shutter speed
to get the correct exposure level. Some cameras also offer an aperture priority
mode
that automatically selects the correct shutter speed to produce the correct
exposure for the aperture you select.
