Aspect ratioN
The image’s aspect ratio can be set to [3:2], [4:3], [16:9], or [1:1].
The area surrounding the Live View image is masked in black when
the following aspect ratios are set: [4:3] [16:9] [1:1].
JPEG images will be saved with the set aspect ratio. RAW images
will always be saved with the [3:2] aspect ratio. The selected aspect
ratio information is added to the RAW image file. When you process
the RAW image with the EOS software, this allows you to generate
an image with the same aspect ratio that was set for shooting. In the
case of the [4:3], [16:9], and [1:1] aspect ratios, the aspect-ratio
lines will appear during image playback, but the lines are not actually
drawn on the image.

The asterisked image-recording quality settings do not match the
respective aspect ratio exactly.
The image area displayed for the asterisked aspect ratio is slightly larger
than the recorded area. Check the captured images on the LCD monitor
when shooting.
If you use a different camera to directly print images shot with this
camera in the 1:1 aspect ratio, the images may not be correctly printed.
