The relationship between the change in exposure c and the change in the required number of stops n is 2.3219.

According to shutter speed, lens F-number, and scene luminance, exposure in photography refers to the amount of light per unit area that reaches a frame of photographic film or the surface of an electronic image sensor.

n = number of stops

c = alteration in exposure

n = log₂C ----- (1)

Suppose n₁ is the number of stops required to triple the exposure.

n₁ = log₂(3C) ⇒ n₁ = log₂3 + log₂C ----- (2)

Utilizing (1) in (2)

n₁ = n + log₂3 = n + 1.5850

Consequently, we must raise the number of stops by 1.585 ≅ 1.6

(b) Similarly, changing C by c/5 will give exposure

n₁ = log₂(c/5) ⇒ n₁ =  log₂C - log₂5

n₁ = n -  log₂5 = n - 2.3219

The required reduction in stops is 2.3219
