What are the different aspect ratios I can choose from? When do I use them?
There are four types of aspect ratios: 4:3, 3:2, 16:9, 1:1.
4:3: This is widely used in various kinds of scenarios, under which your photo gets the highest resolution.
3:2: Best ratio for portrait shooting.
16:9: Best ratio for landscape/scenery shooting.
1:1: Best ratio for shooting a subject with unique composition.
