WebAperture refers to the opening of a lens's diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. Lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller ... WebApr 20, 2024 · How to Measure Aperture in Camera? Photographers calibrate it in f/stops and use this as a number such as 1.4, 2.8…5.6, 7,8, 11, 16, etc. Lower f/stops give more exposure. Because the lower the f/stops, the larger the apertures. And higher f/stops give smaller f/stops as they represent smaller apertures.
