How to Use Programmed Auto Exposure Mode on Your Canon EOS 6D
When you take pictures with the Programmed Auto Exposure mode, the EOS 6D determines the shutter speed and aperture that yields a properly exposed image for the lighting conditions. Even though this sounds identical to Scene Intelligent Auto mode, with this mode you can change the AF mode, Drive mode, ISO speed, picture style, and more. You can also change the shutter speed and aperture to suit what you’re photographing.
To take pictures in Programmed Auto Exposure mode:
Press the Mode Dial lock and Rotate the Mode dial to P.
Press the ISO button and then rotate the Main dial to change the ISO speed to the desired setting.
Higher ISO speeds make the camera sensor more sensitive to light, which is ideal when you’re photographing in dim light or at night. For more information on changing ISO speed.
Press the Shutter button halfway to achieve focus.
The green dot on the right side of the viewfinder appears when the camera achieves focus. If the dot is flashing, the camera can’t achieve focus and you must manually focus the camera.
Check the shutter speed and aperture.
You can use the viewfinder or LCD panel to check the shutter speed and aperture. If you notice a shutter speed of 4000 and the minimum aperture for the lens blinking, the image will be overexposed. If you notice a shutter speed of 30 seconds and the maximum aperture for the lens blinking, the image will be underexposed.
Press the Shutter button fully to take the picture.
The image displays almost immediately on your LCD monitor.
You can shift the exposure and choose a different shutter speed and aperture combination. Use this option when you want to shoot with a faster shutter speed to freeze action or a different aperture to control depth of field. To shift the Programmed Auto Exposure:
Follow Steps 1–3 of the preceding instructions; then press the Shutter button halfway.
The camera achieves focus.
Rotate the Main dial.
As you rotate the dial, you see different shutter speed and aperture combinations in the viewfinder and LCD panel. If you notice that the shutter speed is too slow for a blur-free picture, you have to put the camera on a tripod or increase the ISO speed setting.
When you see the desired combination of shutter speed and aperture, press the Shutter button fully to take the picture.
