How to film the lecture process of history homework

The method of taking pictures during the lecture of history homework;

1, close-up: Close-up pictures can show the details of the speaker's performance, make the characters fuller, and also make the speaker's demeanor change greatly. For example, the close-up shot from a low position can make the characters feel more shocked and the audience have a stronger perception of the speaker's language, but this shooting method will make the promotional film more oppressive and need to be used according to the actual situation.

2. The lens is shot from top to bottom: the lens position is higher than the subject. This shooting technique is used to shoot large scenes, which can well reflect the layering and depth of the picture. In the propaganda film of the speech, the speaker is shot from the back and the top, and the speaker and the audience are brought into the picture together, so that the atmosphere and scale of the speech can be displayed, and the audience's expressions can also be used to render a specific circle.

3. Push the lens to shoot: This is a shooting technique used in the promotional film, which is completed through the zoom lens. The camera position remains unchanged, and the picture gradually approaches the scheduled subject from far and near. In the propaganda film of speech, it is used to highlight the detailed changes of the speaker, such as changes in eyes and expressions.
