The term "f/11" refers to an aperture setting on a camera lens, indicating the size of the opening that allows light to enter. A smaller f-number, like f/2.8, means a larger opening, while a larger f-number, like f/11, means a smaller opening. This affects the exposure of the image and the depth of field, which is the range of distance that appears sharp in a photograph. Using an f/11 setting typically results in a greater depth of field, making more of the scene in focus. This is particularly useful in landscape photography, where capturing details from the foreground to the background is important. The choice of f-stop can significantly influence the overall look of the image.
