What are the properties of light that photographers need to worry about? Here's an overview.
- Light travels in a direction

- Light has color. Not all white light is the same white
- Light can be considered 'Hard' or 'Soft'

Let's refine this to a more practical list of properties that photographers care about on a daily basis.
- Light has a direction.We care a lot about where light comes from, and in what direction that light source is coming from.
- A light source is a certain distance away. We care about how far away the light is, not just how bright it is.
- Light is hard or soft. We care about this quality of light.
- Light has a color.
