| angle of incidence | the more the surface is anlged away from the light the darker its is |
| point lights | omni - single bulb - radiates evenly in all directions |
| dropoff | intensity fades with an increse in its distance from the center of the come to its edge |

| Frontal lighting mood | overhead light - key light is in front and above not to the side |
| side lighting | key light at eye level and in front to simulate sunlight |
| decay | MEASURES amount of fading light |
| falloff | DESCRIBES how light energy is dispersed |
| objects closer to the light are: | brighter |
| attenuation | simulates the fading of light over a distance (decay and falloff) |
| high key | indoor - day but can vary |
| low key | outdoor - night but can vary |
