Setting The Aperture Value - Canon PowerShot SX210 IS User Manual

Setting the Aperture Value

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.
Available Aperture Values
F3.1, F3.5, F4.0, F4.5, F5.0, F5.6, F5.9, F6.3, F7.1, F8.0
• Regardless of the aperture value you set, the camera will set a shutter speed of
1/2000 second or less when the flash fires. However, if [Safety FE] is set to [Off]
(p. 95), the fastest shutter speed is 1/500 second.
• Depending on the zoom position, some aperture values may not be available.
What if the shutter speed appears in orange?
If the shutter speed appears in orange when the shutter button is pressed halfway,
the scene has exceeded the correct exposure limits. Adjust the aperture value
until the shutter speed appears in white. Safety shift can also be used.
Safety Shift
With M and B modes, if [Safety Shift] is set to [On] in the 4 tab, the shutter
speed or aperture value is automatically adjusted for the correct exposure when
it cannot otherwise be obtained.
Safety Shift is disabled when the flash is enabled.
