Description
How the Program AE mode of the EOS 20D, EOS 5D, EOS 30D, and EOS 40D works.
Solution
Like <> (Full Auto) mode, this is a general-purpose shooting mode. The camera automatically sets the shutter speed and aperture value to suit the scene's brightness. This is called Program AE.
P stands for Program
AE stands for Auto Exposure
1. Set the Mode Dial to <P>.
2. Focus on the subject.
Look through the viewfinder and aim any AF point over the subject. Then press the shutter button halfway
3. Check the display.
The shutter speed and aperture value will be set automatically and displayed in the viewfinder and on the LCD panel.
A correct exposure will be obtained as long as the shutter speed and aperture value display do not blink.
4. Shoot.
Compose the shot and press the shutter button fully.
If "30"" and the maximum aperture blink, it indicates underexposure. Increase the ISO speed or use flash.
If "4000"" and the minimum aperture blink, it indicates overexposure. Decrease the ISO speed or use an ND filter to reduce the amount of light entering the lens.
Shifting the program
In Program AE mode, you can freely change the shutter speed and aperture value combination (program) set by the camera while maintaining the same exposure value. This is called shifting the program.
To do this, press the shutter button down halfway, then turn the <> dial until the shutter speed or aperture value you want is displayed.
Program shift is canceled automatically after the image is captured.
If you are using a flash, you cannot shift the program.
