Question

choose the proper f - stop for this aperture. o f/4 o f/16 o f/1.4 o f/8 what is freezing action? o the amount of time that the sensor is exposed to light. measured in a fraction that is a fraction of a second. o the shutter is left open long enough to see any motion o the shutter opens and closes so quickly that a moving subject appears to be frozen.

Explanation:

1. For the first question, a large - diameter aperture (as shown) corresponds to a small f - stop number. Among the options, f/1.4 is the smallest f - stop number indicating a large aperture.
2. For the second question, freezing action in photography means the shutter opens and closes very quickly, capturing a moving subject as if it is frozen in time.

Answer:

1. C. f/1.4
2. C. The shutter opens and closes so quickly that a moving subject appears to be frozen.
