Precautions for taking pictures

The first thing to pay attention to is the most easily overlooked. If you like mobile phone photography, you must form this good habit before shooting: wiping the lens.

The picture of your mobile phone is not clear, probably because your lens is dirty. As long as you don't use hard substances, don't scratch your lenses, and wipe them with the corners of soft clothes. The lens is clean and the photos taken are clear.

The second thing to pay attention to is also the foundation, that is, taking pictures and focusing! No matter shooting scenery, macro or portrait, you should focus! After focusing, the subject is clear, or the whole photo is clear.

Focusing on a mobile phone is simple. Take a picture of a person, for example, on the screen of a mobile phone. Click on this person and a box will appear. Some mobile phones display a circle. The frame is a focus frame. When the picture stops flashing, focus is completed, and then press the shutter. Below is a schematic diagram of Apple's mobile phone focusing, and other brands of mobile phones are similar.
