When increasing the f/stop number, what effect does it have on the exposure?

Increasing the f/stop number leads to a decrease in exposure. This is because the f/stop refers to the aperture setting of the lens, which controls the amount of light that enters the camera. A higher f/stop number indicates a smaller aperture size, resulting in less light hitting the camera sensor.

In photography, exposure is essentially the balance between light and darkness in an image. By increasing the f/stop number, you're allowing less light to pass through, which makes the image darker. This relationship is fundamental in the exposure triangle, which also includes shutter speed and ISO—each of which interacts to manage the final exposure of an image.

While a higher f/stop also affects depth of field, it does not directly relate to color temperature, making options that suggest an increase in exposure or no effect incorrect in this context.
