![]() Alternatively, you can use the d-pad buttons to do the same thing.Ī line in the slider’s middle represents the camera’s recommended aperture. You can raise or lower the f-stop using your camera’s scroll wheel. Once you’ve picked this mode, you should see your current f-stop and a slider to change it. To use this mode, switch the mode dial to the setting labeled Av. It’s similar to shooting in automatic mode, except you determine the aperture yourself. In this mode, you choose the f-stop and the camera automatically picks the rest of the settings. Using Aperture Priority ModeĪperture priority mode is the easiest way to change your f-stop. We’ll start with the easier one and then look at the one that gives more control despite being a bit more work. There are multiple ways to change the f-stop number. The rule of thumb to remember is that a lower f-stop lets more light into the lens and results in a more blurred background, while a higher f-stop lets in less light and blurs the background less. ![]() These lenses can take in a lot of light, allowing the photographer to use high shutter speeds without underexposing the image.Īperture is also relevant in low-light photography, where it’s important to make the most of what little light is there. The lower the f-stop, the more open the lens is.įor example, sports photographers typically use lenses with low minimum apertures, such as f/2.8. ![]() On the other hand, F-stop is the number used to measure aperture. But what do they actually mean?Īperture refers to how wide the lens opens to allow in light. In fact, many photographers use the terms interchangeably sometimes. How to Change The F-Stop on Canon Cameraį-stop is closely connected to the aperture.In fact, the opposite applies.į-numbers typically range from f/1.4 to f/22 depending on your lens, with smaller numbers representing a wider aperture and larger numbers signifying a smaller, or more narrow, aperture. However, the way that f-stops are written can be confusing as a smaller f-number does not equal a smaller aperture. Are aperture and f-stop the same thing?Īperture and f-stops are essentially the same thing, with the aperture being how wide the lens opening is and the f-stop being the value that controls it. To avoid over or under-exposing an image, you’ll want to adjust the other aspects of the exposure triangle to compensate. This makes narrow apertures a popular choice for taking photos on sunny days when there’s already plenty of light. However, images taken with a narrow aperture will be less bright as they are not as exposed. For this reason, f-numbers around f/16 and above are useful in these instances. Photos shot with a wide aperture are also brighter, or more exposed.Ī narrow aperture, on the other hand, keeps both the subject and background sharp and is a common choice for landscapes and group photos. This makes wider apertures signified by f-numbers around f/2.8 or below ideal for portraits. This is also what creates a bokeh effect when shooting in front of fairy lights and street lamps. The f-stop affects how your final image looks by controlling the aperture, and thus both the exposure and depth of field of the photo.Ī wider aperture equals a more shallow depth of field with a blurred effect behind the subject. This can be done by either opening up the lens to allow more light to reach the sensor or narrowing the opening to limit the amount of light that enters the camera. Increasing or decreasing the f-stop allows photographers to adjust the aperture. The “f” in f-stop refers to the focal length of the lens.Īperture controls how much light is able to enter a camera, which affects both the exposure of an image as well as the depth of field achieved. The f-stop (or f-number) is the way in which photographers measure aperture on a camera.
