It makes sense, right?įun fact! Way back in the early days of photography, the photographer manually adjusted the opening on the lens (or f-stop) by inserting metal plates into the front of the lens.
If you’re going to use a small aperture, you want a larger number, like f/16 or f/22. If you want to use a large aperture, you want a smaller number, like f/1.8 or f/4. I need those words for myself, but I also think others out there like me need the reminder. This is why you will see in almost all of my posts that I put the words (bigger number) or (smaller number) behind any mention of wide-open aperture or stopped down aperture. Starting to make sense? This information took forever for me to get into the logic portion of my brain! I could not understand why a bigger number was equal to a smaller aperture for the life of me. The same mathematical theory applies when looking at f-stop and why an f/stop of f/22 is smaller than an f/stop of f/2.8. For example – ¼ cup is smaller than ½ cup. If you know basic math, remember that the bigger number on the bottom means a smaller measurement. Think of your f/stops as the fraction of how far open the diameter is in s iris of the camera. It’s just that simple.Īperture is written as an f/number because it represents a fraction. You need to know that the number correlates to the size of the opening of your aperture. The number behind the F is the ratio of the lens’ focal length to the diameter of the entrance pupil. Spend any time shooting in manual, and you will hear the term f-stop concerning aperture. You can see below how the lens can open and close through the f-stop settings in the lens.īy KoeppiK – Own work, CC BY-SA 4.0, What is an F-stop? Take a look at the diagram from Wikipedia that visually shows what all of that looks like. If you want to dig deeply into the inner workings of a camera lens, you can see more from Wikipedia HERE. The Iris is the name given to the aperture blades that open and close to allow light through the diaphragm. In the center of the diaphragm is an Iris. In photography, there is a diaphragm inside of your cameras lens that blocks light. This moving diagram of how the aperture blades open and close within the lens gives a great vision of what is happening inside the lens when you adjust your aperture.īy Pasimi – Own work, CC BY-SA 4.0, All the fancy words Aperture blades open and close that hole allowing or stopping light from reaching the camera sensor.
APERTURE 3.5 CAMERA FULL
Sometimes I am, too) from Wikipedia: “Aperture is defined as a hole or an opening through which light travels.” You can see the full definition HERE. Here is the more scientific, albeit geeky, answer (it’s okay if you’re on the geeky side.
Since photography is based on how much light comes into the camera, this is a fundamental principle to understand. In short, aperture blades are part of the mechanism within the camera lens that allows or blocks light from entering the camera and reaching the sensor. What is it, how do I control it, and how can I use it to improve my photography? 1 – What the Heck is Aperture Anyway? It can be overwhelming, so let’s make it easier with five facts that you need to know about aperture. “Aperture” is just one of the many bits of jargon to sift through. What the heck are aperture blades and f stops, and where are they in my camera anyway? When you begin learning photography, there are so many terms to learn.
