Do you know how to adjust the parameters of your mobile phone when shooting in the street?

Aperture directly affects the depth of field, so when shooting in large depth of field, it can be as small as possible without shaking, and vice versa. If the aperture is large enough (for example, small spittoon 50 1.8, portrait shooting can be opened to 2.8), the same is true. ISO, in a word, is as small as it can be. If you need a large depth of field or a high shutter, you can only add it.
