I think the previous research is very important for documentary filming. For example, in terms of sound collection, in the early stage, the director should be aware of the possible performance of the live sound during the research – what subjects should be filmed in the film, what kind of life and living conditions they will be, what may happen. Scenes? In these scenarios, what is the need to focus on recording sounds? Which sounds are brilliant? Which sounds must be compensated in the later stages of the scene? Only when you understand the scene of the shooting scene and design accordingly, you can do it in a real shot without being overwhelmed.

I will shoot across different regions and use the techniques of time and space conversion. The food documentary should record the specialities of different regions. The scope of the food is wide. The various foods in different regions condense the labour and local characteristics of the people. The lens is used in multiple regions across time and across the film. For example, the impressive title, using a large number of fast-cut lenses, using the perspective and panorama on the scene to express a wide range of scenes, rendering an atmosphere. All in all, it is through the multi-regional shooting across time to show the characteristics of different regions. This will make the documentary look rich in content.

Close-ups can show the characteristics and details of the characters and time in the documentary. If the documentary photographer can be the last one, I will use the close-up. Close-ups make it easier to show the actual state of the person being photographed, making it easier to resonate with the audience. At the same time, the good use of close-ups can more accurately express the plot content of the documentary filming, which makes the audience’s sense of substitution more intense, thus triggering the true feelings of the audience.
