<Aperture-priority AE and shutter speed-priority AE>
For the exposure control, the PowerShot G1 has the aperture-priority AE and shutter speed-priority AE modes. With
aperture-priority AE, you set the desired aperture and the camera sets the shutter speed automatically to match the subject
brightness. Setting a large aperture increases the background blur which better isolates the subject in the foreground.
Setting a small aperture attains greater depth of field to make subjects both in the foreground and background look sharper.
The farther you zoom in to your subject, the better the background blur. With shutter speed-priority AE, you set the
desired shutter speed and the camera sets the aperture automatically to match the subject brightness. A fast shutter speed
can freeze the subject’s movement, and a slow shutter speed can blur the subject to give the impression of motion.
<Manual focus>
Manual focusing is possible with the PowerShot G1. In sports or wildlife photography, you can set a specific focusing
distance previously and take the shot when the subject comes into focus.
Manual focus is also effective when autofocusing is not possible in the following cases:
-Extremely low-contrast subjects
-Near and far objects overlaid at the same position
-Severe backlit conditions or highly reflective surfaces
-Extremely bright objects ata the center of the composition
-Very low-light scenes
The focal point can be moved manually by holding down the MF button and pressing the Omni Selector. The MF indicator
is shown on the LCD monitor as a reference for the focal range.
