So again, the bigger the f-number, the smaller the aperture, and the darker the image, the smaller the f-number, the larger the aperture, and the brighter the image. Moving forward, reducing the aperture reduces the brightness, and as you notice, the values on the second and last images are f/8 and f/22. In the example below, you can see how the aperture affects the brightness of an image (exposure).įrom left to right, the initial “small” value of f/2.8 allows more light to enter the camera and hit the sensor. And that’s something that confuses a lot of photographers in the beginning, but it’s a super important thing to get right from the start. The bigger the f-number the smaller the aperture. The smaller the f-number the larger is the aperture. Take a look at the chart and find the catch. Those are f-stops and describe the size of the aperture. You might have noticed before that your camera viewfinder displays some numbers such as f/2, f/5.6, f/11, and so on.

Let’s now introduce the concept of f-stop and how to measure aperture. How to Obtain Bokeh (creamy background).Photography Basics: Understanding Shutter Speed.It’s essential to understand quickly that mastering this camera setting will allow you not only to improve your photos dramatically, but it will open the door to mastering the depth-of-field and take your expertise to the next level. The size of the lens opening is the aperture, and it’s measured in f-stops. When taking a photo, your lens diaphragm opens up for a certain amount of time ( exposure time), and it allows the light to hit the camera sensor and record the image.
The aperture affects the brightness (exposure) and the depth-of-field on a photo. f/2, f/4 … f/22, etc.) The Effect of Aperture on a Photograph How to Measure the ApertureĪperture is measured in f-stops or f-numbers (e.g. The aperture of a lens is the size of the opening that allows light through into the camera body. Before we jump straight into the details, let me make a few points A perture Definition
