Multiple choice general knowledge science & technology

Almost all professional cameras have an iris which controls the amount of light that can enter the camera and expose an image. This iris uses f-stops settings which are expressed in fractions to control the light. Therefore which number is the largest?

  1. 1/16th

  2. 1/8th

  3. 1/12th

  4. 1/32nd

B Correct answer
Explanation

In f-stop notation, a smaller denominator number means a larger aperture and more light. Among these fractions, 1/8 is the largest value, allowing the most light. 1/32 is the smallest (least light), with 1/16 and 1/12 being intermediate values. This counterintuitive concept often confuses photography students.
