F-stop
The f-stop, or f-number, is a key concept in photography that indicates the size of the lens aperture—the opening that lets light into the camera. A lower f-stop number (like f/2.8) means a larger aperture, allowing more light in and creating a shallower depth of field, which blurs the background. A higher f-stop number (like f/16) means a smaller aperture, allowing less light and increasing the depth of field, keeping more of the image in focus. Adjusting the f-stop helps photographers control exposure and focus in their images.

F-stop is a measure of a camera's aperture, which controls how much light enters the lens. It’s represented by numbers like f/2.8, f/4, or f/8. A lower f-stop number means a wider opening, allowing more light and creating a shallower depth of field, which helps blur the background. Conversely, a higher f-stop number means a smaller opening, letting in less light and increasing depth of field, which keeps more of the scene in focus. Adjusting the f-stop helps photographers manage exposure and creative effects in their images.
