Question | Answer |
What is ISO? | Measurement of how sensitive the sensor is to light/how rapidly it records light. |
What is the aperture? | The opening in the lens, measured in F-stops. |
What are F-stops? | Numbers representing the size of the aperture. The most common ones (from sm to lg) F22, 16, 11, 8, 5.6, 4, 2, |
What is shutter speed? | The speed at which the shutter opens and closes, controlling the amount of light in and out of the camera. Typical numbers associated with it is: 2000, 1000, 500, 250, 125, 60, 30, 15, 8, 4, 2, 1", 2", 30". 15 is the slowest w/o tripod. |
What would you use fast shutter speed for? | Action shots |
What would you use slow shutter speed for? | To capture movements with blur. |
What is an advantage of using the slow or low ISO and what number would be a low ISO? | 100 ---- gives you high resolution. |
Why would you not want to use a fast or high ISO and what number would be a fast one? | 3200 ----- has lots of noise/grain. |
In what circumstance would you use a large aperture? | For a shallow depth of field. |
In what circumstance would you use a small aperture? | For a large depth of field. |
Which are the most common number associated with ISO (from fastest to slowest)? | 3200, 1600, 800, 400, 200, 100. |
What are the most commonly used F-stops (from smallest to largest)? | f22, f16, f11, f8, f5.6, f4, f2. |
What is reciprocity? | The relationship between the aperture and shutter speed that allows for change in DOF, but allows the same amount of light in. |
