Aspect ratio

Should I change my aspect ratio in camera itself or can I crop it later? Will this make any difference? - Zainab Siraj, Surat

In most cameras, the default aspect ratio setting is 4:3. If you choose to shoot in 1:1 or 16:9, the camera’s sensor will simply add or remove the pixels to give you that aspect ratio. This is the same as cropping the image to your desired ratio later in post production. However, one advantage of setting your aspect ratio in camera itself is that you will be able to compose and frame better according to the ratio you have chosen.

Whereas at times while cropping it later, you may realise that the framing is not quite right for the desired aspect ratio.
