2025年1月19日 · Also known as aperture size, the f-stop controls the amount of light that passes through the lens at a given shutter speed. All else being equal, a smaller aperture (like f/16) allows in less light than a larger one (like f/4), meaning it takes longer for the same amount of light to reach the sensor.

Lower F-Numbers: A smaller number like f/2.8 indicates a wider aperture. This means more light can enter, which is excellent for low-light scenarios. But remember, a wider aperture also means a shallower depth of field, so the focus will be narrow. Higher F-Numbers: On the flip side, a higher number like f/16 signifies a smaller aperture. While ...
