Lighting Ratios

1. In your own words, explain what lighting ratio's are.
2. What is high key lighting used for? What is low key lighting used for?
3. How can you put this principle into effect with your film noir shoot?

Lighting ratio describe the amount of contrast a certain set of lights create. In simple terms, the fill and key lights will create the ratios. Lighting ratios can be kept with different intensities of light as long as the other lighting sources change in intensity accordingly. High key lighting can be used to create a dramatic look while a low key lighting can be used t =o create a typical, comedic tone to the film. Different lighting ratios can achieve looks from dramatic to undramatic. In the film noir shoot, this principle can be used to associate drama with the lighting. According to the scene's mood, I can alter the lighting ratio.
