Key points of lighting course：
1.Identifying those techniques from the plate / reference and re-create the CG lighting:
1.1. Three-Point Lighting —— Position and the direction of different light sources
1.2. High-key and Low-key Lighting —— The contrast ratio of the Key and Fill on the subject.
1.3. Hard and Soft Lighting —— Transition from the Light area to the Shadow area
1.4. Colour Temperature —— Define the time and space of shot is taking place in the story
1.5. Creative Lighting —— Adding complexity to the lighting of the image
2. Knowledge in Physically-Based Rendering
2.1. Simulating light
2.2. Behaviors of light on different material
2.3. Method to Generate image
2.4. Light Sources
study notes：
1.In the past, I only used key lights and fill lights in the process of building scene lights. In this course, I realized that backlights can be built to highlight the outline of characters or themes.。
2. The smoother the surface is, the higher the refractive index of light is. A more accurate setting of light reflection of object material can better express the texture of the object.
Analyze the lighting used by the <God Father>
In this assignment, I chose to analyze the lighting effect of the famous film “Godfather”.
First of all, the most classic lighting setting of this film is the top light, which is created by director Gordon with his usual “chicken poop” lamp. This kind of lamp can make a lot of changes. Sometimes Gordon will use his own light lamp to achieve the godfather light effect in the real scene. If understood as the concept of CG, it is to add a spotlight or a piece of light at the top of the character.
In this movie, in order to make the picture not monotonous and inflexible, he will use other objects to produce some bright light to illuminate in the dark. This kind of high light in the dark and the top light of the characters work together to give people an unforgettable feeling. The result of this is not only to enhance the impact of the lens, but also to break the Convention, let the characters in the dark, break the rigid and monotonous.
