Triangle of Exposure

1. Aperture: Control of how much light is let through. Also controls depth of field
2. Shutter speed: how fast the shutter on the camera moves. Slower shutter speeds will allow for more motion blur
3. ISO: The standardized system for measuring film speed.
4. Depth of field: the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image
5. Motion blur: the streaking in an image that comes from an image being captured for an extended time period while it is moving
6. Noise and light sensitivity: Noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. Light sensitivity is the level of light that the camera shows in the picture.
