By increasing the aperture size of a lens from f/11 to f/8, how does this affect light transmission?

• A. Halves the light
• B. Doubles the light
• C. Reduces light
• D. Increases light by three times

Answer: (B)

When the aperture size of a lens is increased from f/11 to f/8, this adjustment allows more light to enter the camera. The f-stop scale is a logarithmic scale, meaning that each full stop change in the f-number either halves or doubles the amount of light that reaches the sensor. Moving from f/11 to f/8 represents a change of one full stop. Each full stop increase (lowering the f-number) doubles the light that enters the lens. Therefore, increasing the aperture size from f/11 to f/8 effectively doubles the light transmission, enhancing the brightness of the image captured. This principle applies to setting the aperture for desired exposure in photography, where understanding how f-stop adjustments impact light is crucial for achieving optimal results.
