To determine which f-stop value lets in less light, we need to understand the relationship between f-stop values and the aperture size. The f-stop number (also known as the f-number) is inversely related to the size of the aperture. This means that the larger the f-stop number, the smaller the aperture, and thus, the less light that enters the lens.
We are given the following f-stop values to compare:
- f/2.8
- f/5.5
- f/6
- f/16
We need to identify the highest f-stop value among these options. The higher the f-stop value, the smaller the aperture and consequently, the less light will be let in.
Comparing the f-stop values:
- The f-stop value of f/2.8 is less than f/5.5.
- The f-stop value of f/5.5 is less than f/6.
- The f-stop value of f/6 is less than f/16.
- Therefore, f/16 is the highest f-stop value among the given options.
Since f/16 has the highest value, it will let in the least amount of light.
So, the answer is:
d. f/16
