The term "f/8" refers to an aperture setting in photography, indicating the size of the lens opening. The "f" stands for "f-stop," and the number represents the ratio of the lens's focal length to the diameter of the aperture. An f/8 setting allows a moderate amount of light to enter the camera, making it suitable for various lighting conditions. Using an f/8 aperture typically results in a greater depth of field, meaning more of the scene will be in focus. This setting is often favored for landscape photography, where capturing detail from foreground to background is essential, and is commonly used with cameras like DSLRs and mirrorless cameras.
