2 Use aspect ratios to improve composition
Move beyond your camera’s default image format mode and you’ll soon be able to visualise and plan your photography in a whole new way,
says Niamh Cottle
W hen was the last time you changed your camera’s aspect ratio – if ever? The aspect ratio expresses the relationship between the height and width of an image, and is determined by the physical form of your camera’s rectangular imaging sensor. And although full-frame and APS-C sensors are different in size, they both have a default aspect ratio of 3:2. Four Thirds sensors, as their name indicates, have an aspect ratio of 4:3.
But dig into your camera’s menus and you can easily change this setting. For example, my Canon EOS 77D DSLR also offers 1:1, 4:3 and 16:9 aspect ratios.
