Lenses with larger apertures are called fast because this allows the photographer to use a higher (faster) shutter speed! What is the theoretical fastest lens possible? Why are lenses called “fast”?Ī lens with a larger aperture lets more light into the camera. To make this less confusing, check out our video which explains the differences between aperture and fstops. F stops are calculated by dividing a lenses focal length by its aperture. But aperture is commonly incorrectly referred to when talking about a lenses f-stop, which is a measurement of how much light a lens funnels into the camera. Aperture is technically the diameter of your lens opening that allows light into the camera. For an in depth explanation, watch our video explanation of aperture and depth of field! Is aperture the same as f-stop? The larger the hole, the greater the angle of light entering the camera, which results in a shallower depth of field. Simply put, the aperture of a lens is the size of the hole allowing light to pass through to the camera.

#APERTURE AND F STOP HOW TO#

Aperture is one of the most important components to photography, so its essential to have an understanding of how aperture works and how to know what to set your aperture to! Ready? Lets dive in.Ĭommon questions people ask about aperture: Why does aperture affect depth of field? Not just the technical definition for aperture and how aperture is calculated, but how using aperture affects your photography. The problem is there aren’t a lot of good tutorials explaining what aperture is and how aperture works – So we decided to sit down and tackle aperture in depth. When it comes to learning photography basics, the terms can be a little daunting! Nowhere is this more the case than with aperture. (Remember that each stop, whether shutter speed increment or f/stop, allows for 1/2x or 2x the light transmission.)įor example, if you have an indicated exposure of 1/30 sec.What Is Aperture? Aperture & f-stop explained! What Is Aperture? A simple explanation of Aperture & F stop! You can increase one while decreasing the other an equal amount to get the same light exposure on film. Shutter speed and aperture are used in combination to achieve the desired exposure result. allows only half as much light as 1/15 sec., because the film is only exposed for half the time. allows twice as much light to reach the film as 1/250 sec. Shutter speed works similarly, but controls the amount of light reaching the film plane via the length of time the shutter is open. f/5.6 allows twice as much light as f/8).

(Note that each full f/stop allows either twice or half as much light through as the previous one - depending upon which direction you're going.

Opening the aperture wider (such as opening from f/16 to f.2.8) allows more light to get through the lens.

Can you help me out?Ī: Aperture (f/stop) and shutter speed are both used to control the amount of light that reaches the film. Q: I have taken a photography class at school and the instructor totally confused me on whether you need a high /low shutter speed or a high/low F-stop when taking outdoor pictures when there is an overcast.
