Depth

1. Why is value relative?
   
   Because it helps give a visual interpretation of the weight of an object based on its color and it's contrast between it and the surface.
   
   
2. Why might high contrast be especially important to commercial artists?
   
   It tends to increase clarity and improve readability.
   
   
3. How can value help create an illusion of volume, space and depth?
   
   Darker values usually mean that something is closer to you as opposed to when it's lighter, then it is moving away from you and going deep into space.
   
   
4. How many different devices are there to show depth? Name them.
   
   Linear perspective, overlap, size variation, definition
   
   
5. In order to understand linear perspective, what must be present?
   
   A picture plane that allows you to find horizon lines and different vanishing points to create a drawing that is in perspective.
   
   
6. What is the difference between one-point perspective and two-point perspective?
   
   One point occurs when the lines receding into space appear to converge at a single point on the eye level. Two point is used when the lines converge at two vanishing points on the eye level.
   
   
7. What kind of linear perspective is closest to what you see in photography? Why?
   
   3 point because it is a more realistic view of our perspective in the real world. In photographs, one point or two point seems more likely.
   
   
8. When would it be appropriate to use depth in composition? When should it be avoided?
   
   When your trying to create an illusion of space in your composition. It should be avoided when your creating something in 1 point perspective.
