Changing the Compression Ratio (Image Quality)

Approximate Values for Recording Pixels and Compression Ratio (for 4:3 Aspect Ratios)
The values in the table are measured according to Canon standards and may change
depending on the subject, memory card and camera settings.
The values in the table are based on 4:3 aspect ratio. If the aspect ratio is changed
(p.90), more images can be shot because the data size per image will be smaller than
with 4:3 images. However, since 16:9 images have a setting of 1920 x 1080 pixels,
their data size will be larger than 4:3 images.
