How to focus the manual lens quickly?

1. Just touch the shooting focus in the frame with your hand, and the camera will automatically select it as the focus of the photo and partial metering it, so that you can get the clearest focus and the best light. Manual focusing by touching the screen has become the most effective focusing method, because most mobile phones only have autofocus function. Accordingly, because the mobile phone doesn't know where the photographer wants to focus, it can only evaluate and measure the light, which makes it difficult for the photographer to highlight what he wants to express in the photo.

2. The most important thing is to set the parameters of the mobile phone camera in advance. For example, whether to turn on the flash, whether to use autofocus, and what kind of resolution to choose. The setting of these parameters is an important prerequisite for obtaining the best image. Generally speaking, when taking landscape photos, try to shoot in natural light, so that the photos taken are more natural; If the mobile phone has a choice of photo size, try to choose a large resolution, so as to ensure that the picture has sufficient resolution.

3. In the process of shooting, try to expose the subject to natural light, such as shooting portraits in the sunset. It is best to let the subject face the sunset and never shoot against the light. If you shoot a portrait in bright sunlight, it is best not to point the lens at the sun unless you are not afraid of overexposure or can shoot a backlight effect.
