What is the aspect ratio of the camera setting and what is its function!

The aspect ratio is the aspect ratio of the frame set by the camera, such as 3:2, 4:3, 16:9, etc. It can help you make a better composition, and it can also help you identify when to cut to different aspect ratios to improve the composition of the image, thus affecting the photographer's creative intention and photographic composition.

The aspect ratio of an image is mainly determined by the size of the camera sensor. The latest digital cameras allow you to change the aspect ratio by using the camera menu.

Common aspect ratios of cameras:

1、3:2

EOS digital camera has the same aspect ratio as CMOS image sensor. Suitable for a variety of scenes, horizontal and vertical composition is very convenient.

3、 16:9

Among the four aspect ratios, the long side is the longest, which can present the effect like a movie scene, and is mostly used for horizontal composition.

4、 1: 1
