I should note that not every lens will have the same aperture capabilities. There are pros and cons that you need to consider when increasing and decreasing the size of your aperture, which we will discuss below.įor now, just know that your aperture is an opening that you can adjust to control how much light hits your sensor, and is partly responsible for the proper creation of your photograph. Open the faucet (open/widen the aperture blades), and more water comes out…close the faucet (close the aperture blades) and less water comes out. Your aperture is the faucet which controls how much water (or light) is filling the bucket. This is like your camera sensor being exposed to a certain amount of light in order to create an accurate image. Imagine a bucket being filled with water, and there needs to be a certain amount of water to fill it properly. When creating a photo, you’ll be adjusting the size of the aperture (the pupil) depending on how much light is needed for the camera to properly “see” the image.Īnother analogy that is often used to explain aperture is the “water bucket”. It’ll get smaller to compensate for the vast increase in light so you can properly see. Going back to the eye example: adjusting your aperture would be like your pupil dilating as you move from a dimly-lit room to the bright and sunny outdoors.

You’ll use your camera to control the size of this opening depending on how much light you want to let in, but the actual aperture is located in the lens itself. If you contract the blades, the hole gets smaller with sharper corners so less light passes through. The aperture itself has blades that overlap: if you widen the blades, the hole gets bigger and rounder so more light can pass through it. What is Aperture and How it Creates a Photograph How the Camera Aperture WorksĪs mentioned earlier, the aperture is an opening on your lens which controls how much light that the sensor is “exposed” to, thus rendering your photograph.

The more you practice, the easier it will get…and soon, adjusting your aperture and your other manual settings will become like second nature. By breaking it down into separate subjects and then explaining how they all work together, you can more easily practice in the field and learn how to choose the correct f/stop, aperture, and lens for the image you want to create. That is why I wanted to put together this simple guide to aperture for beginners. This can be a complicated subject to learn and can take some time to grasp fully as there are several variables that will determine the best aperture for your photograph. However, the key to using your aperture (and your other manual settings) successfully is understanding the concept: the role it plays in the exposure triangle, how it affects your depth of field, and the different scenarios where you’ll want to change the aperture size to either limit or expand on the amount of light that enters the lens. The same rules apply to your camera aperture. Either way, the pupil reacts to the light so you can see properly.
