Canon G12 Digital Camera User Manual


 
Setting the Aperture Value
105
You can set the aperture to a value at which you want to shoot. The camera
will set the appropriate shutter speed for the aperture value you set.
B stands for “Aperture value”, which refers to the size of the aperture
opening inside the lens.
Set the mode dial to B.
Make the setting.
Turn the ÷ dial to set the aperture value.
Shoot.
Available Aperture Values
Depending on the zoom position, some aperture values may not be available.
When shutter speeds of 1.3 seconds or slower are used, images are
processed to eliminate noise after being taken. A certain amount of
processing time may be needed before you can take the next shot.
You should set the [IS Mode] to [Off] when lowering the shutter speed
and shoot with a tripod (p. 171).
What if the aperture value appears in orange?
If the aperture value appears in orange when the shutter button is pressed halfway,
the scene has exceeded the correct exposure limits. Adjust the shutter speed until
the aperture value appears in white. Safety shift can also be used (p. 106).
You can also set the camera so that turning the ÷ or Ê dial changes the
aperture value (p. 171).
