The Visual Story Chapter 3: Space 3.1 Deep Space

Last week I got a book, name is The Visual Story written by Bruce Block. I read the part of space. There are four subcomponents of space: deep, flat, limited and ambiguous. This week I just read one of them. I will finish read it before next week. The part is talk about how 2D screen surface display picture that appear to have 3D? It is not 3D movie, it is make a 3D picture in 2D screen surfaces.                                                                                         

When we take a picture, a different angles can create a deep space. The building near the camera is bigger than long distant building. It is a principle, size different. That can make a depth of cue.In addition, we can find vanishing point in the picture. If we extent the road, it will become a point. The point is vanishing point. 

Object Movement

The two objects in front of camera, one object in the foreground another in the background. Two objects use same speed in the same starting line, the background object slower than the foreground object. Actually, they move same distance but audience can feel background object appear slower and shorter movement. This is illusory depth. 

Camera Movement

The camera dollies in, the foreground object will get bigger than background object. The background object just has a slight changes.The relative movement between the foreground and background is the depth cue.
Additionally, the textural diffusion, aerial diffusion and shape change that all of help us to make the deep space in the 2D screen. And deep space can highlight the subject in the complex environment. The lens language of space can make the documentary more tension and engage audience emotionally.
