What Is Color Grading And Color Correction

 

What is aperture in photography? How does it work? And how can you use it to capture photos like the pros?

Aperture is an essential camera setting; in my opinion, it’s where the magic happens in photography. So in this article, I’m going to take you through all the ins and outs of aperture, including:

• What aperture actually is (in simple, easy-to-understand terms)
• How you can use aperture to capture artistic images
• How to choose the perfect aperture for landscape photography, portrait photography, and more
• Plenty of other tips and tricks!

If you can master aperture, then you’ll gain a huge amount of creative control over your photography.

Ready to take your photos to the next level?

Let’s dive right in, starting with the most important question of all:

What is aperture?

Aperture is the opening in the camera lens. A larger hole allows more light to hit the sensor, lightening your photos. A smaller hole allows less light to hit the sensor, darkening your photos.

And by adjusting the aperture setting on your camera, you can adjust the size of the aperture (and, in turn, affect a photo’s brightness).

Aperture and f-stops

Aperture is measured in terms of f-stops, also known as f-numbers. Like this: f/2.8, f/4, f/5.6, f/8, f/22, etc.

As shown in the diagram below, the smaller the f-number, the larger the aperture hole:

Now, each full stop corresponds to a halving of aperture size. So when you go from f/2.8 to f/4, you cut the aperture in half. And when you go from f/4 to f/5.6, you cut the aperture in half again.

(Of course, to double the aperture size, you just go in the reverse direction: from f/5.6 to f/4, and from f/4 to f/2.8.)

Does that make sense? It can be confusing at first, especially because large aperture sizes correspond to smaller f-stop numbers and vice versa. But stick with it, and it’ll become second nature.

How does aperture affect your photos?

At this point in the article, you should know what aperture is: a hole in the lens that increases and decreases depending on your camera settings (i.e., your f-stop value).

But what does aperture actually do? How does it affect your photos?

In the next two sections, I’ll discuss the primary effects of aperture:

1. Exposure
2. Depth of field

Aperture and exposure

As you may already know, exposure refers to the brightness of a photo.

In general, the goal is to end up with a photo that’s not too dark and not too bright; instead, you want a shot that’s just right, one with lots of detail.

So where does aperture come into play?

Aperture is one of the three key variables that affect your exposure. (The other two variables are shutter speed and ISO.)

Remember what I said above? By widening the aperture, you let in more light, which brightens your image. And by narrowing the aperture, you let in less light, which darkens your image.

So if you’re photographing a beautiful sunset and your photos keep turning out too bright, you can always narrow the aperture to darken down the image. (In fact, using a narrow aperture is often a good idea when shooting sunsets!)

As you can see, the effect is pretty artistic; you get a sharp subject but a blurry background. Neat, right? Because a blurry background helps the subject to stand out, this is an effect you’ll often see in portrait photography.

As for aperture, the wider the aperture (and the smaller the f-number!), the shallower the depth of field.

So an image with an f/2.8 aperture will have very little in focus:
