The flash on the Canon PowerShot G9 digital camera shuts off by means of a quick access button on the back of the camera that brings up a flash menu system on the screen. The G9 has an automatic flash feature in which the camera's sensors determine if the lighting conditions are right for a good photograph. When the camera "thinks" lighting conditions are good, the flash turns off, and when lighting seems poor, the flash turns on. The G9 also has the option for the flash to fire each time a picture is taken. You may want to turn off the flash if the subjects of the photographs you take with the flash are too bright.
Instructions
1. Press the "On/Off" button on the top of the camera, below the shutter button, to turn on the camera.
2. Turn the mode dial, which is to the left of the "On/Off" button, to any of the photograph shooting modes, which are labeled "Auto," "SCN," "P," "TV," "AV," "M," "C1" or "C2." In "Auto" mode the camera automatically adjusts the shutter speed, which determines how long the shutter is open to allow light into the camera; aperture, which determines the amount of light allowed to enter the camera; International Standards Organization, or ISO, which determines the camera sensor's sensitivity to light; exposure compensation, which makes adjustments to the exposure when the subject is too dark or too light; and the white balance, which determines how some colors appear in a photograph in different lighting conditions. Many users prefer the "Auto" setting as it adjusts the camera according to the conditions of each shot. The "Auto" mode does not determine if the camera flash is used.
"SCN" mode is a selection of common photograph types with predefined camera adjustments. For example, one scene selection you can choose is "Night Scene" for when you are taking shots at night. When in "P" mode, the camera sets the shutter speed and aperture and you can adjust the ISO, exposure compensation and white balance. In "TV" mode you choose the shutter speed while the camera makes the rest of the adjustments. "AV" mode allows you to change the aperture while the camera adjusts the other settings. In "M" mode, you can adjust both the shutter speed and aperture. The "C1" and "C2" modes allow you to save custom settings that you use often so you don't have to spend the time making adjustments you regularly make.
Many users prefer "Auto" mode since the camera makes all of the adjustments automatically.
3. Push the right navigation button on the back of the camera to display the flash options on the screen and then press the right button repeatedly until the symbol of a lightning bolt with a circle around it and a line through it shows as highlighted. The right arrow button on the camera has a symbol of a lightning bolt on it. The other two flash options are to turn on the flash, symbolized by a lightning bolt, and automatic flash, symbolized by a lightning bolt with an "A" next to it. When set to automatic flash, the G9's flash only operates when the camera sensor determines there is not enough light for the photograph.
4. Push the "Func./Set" button to select the flash setting. The "Func./Set" button is in the middle of the navigation buttons on the back of the camera.
