F-number, also known as aperture value, is the measure of the size of the opening of a lens. It is represented by a number, such as f/1.8 or f/22, and controls the amount of light that enters the camera.
F-number directly affects depth of field, which is the range of distance in a photograph that appears to be in focus. A lower f-number (larger aperture) will result in a shallower depth of field, while a higher f-number (smaller aperture) will result in a greater depth of field.
F-number and shutter speed are both important settings in photography and are closely related. A lower f-number (larger aperture) allows more light into the camera, so a faster shutter speed can be used to properly expose the photo. On the other hand, a higher f-number (smaller aperture) requires a slower shutter speed to allow enough light into the camera.
F-number can be adjusted on most cameras, including DSLRs, mirrorless cameras, and some point-and-shoot cameras. However, some basic point-and-shoot cameras may have a fixed aperture and cannot change the f-number.
The best way to control depth of field using f-number is to use a larger aperture (lower f-number) for a shallow depth of field, and a smaller aperture (higher f-number) for a greater depth of field. Additionally, using a longer focal length and getting closer to your subject can also help create a shallow depth of field effect.
