Price Comparisons Digital F Stops Explained
Anyone who has taken up photography will quickly run into two terms when they discuss or read about the correct way to expose a photograph, and those terms are openings and f stops. While they sound different, they are actually the same exact thing.
What is aperture? It translates to the part of a lens that dictates how much light is let through to the camera's sensor-when it is wide open, lots of light gets through. When it is closed down, not much light gets through. The aperture is adjusted through the camera's f stops, which are discussed as decimals and work in a sort of inverted fashion. This means that the smaller the f stop number the larger the aperture, and vice versa. Understanding f stops is important for making the proper exposure for the desiredresults.
While there are charts and tables with f stops recommendations for a photographer to follow, it is best to understand the various needs of any type of photography and also what the right settings should be to get the desired results. For example, it is vital that a photographer has an understanding of aperture and shutter speed, because they cannot work independently of one another. Aperture controls the depth of field in the photograph and it controls the amount of light on the sensor. This means that if the aperture is small, which also means a higher f stops, shutter speed the is going to have to be slower to allow in enough light.
