Understanding Aperture
Guide for your doll photography
If you’re into doll photography – or photography in general – you’ve probably heard the term “aperture” thrown around. It’s one of the most important settings on your camera, but it can also be a bit confusing at first. Don’t worry – in this guide, we’ll break it down for you in simple terms, using doll photography examples to make it easier to understand. By the end, you’ll have a good grasp on what aperture is and how you can use it to improve your photos.
Remember: Aperture is just one element of the exposure triangle, which also includes shutter speed and ISO – all three work together to control the overall exposure of your photo.
What is Aperture?
In its simplest form, aperture refers to the size of the opening in your camera lens. This opening controls how much light enters your camera and reaches the sensor. Think of it like the iris of your eye: when it’s wide open, more light comes in; when it’s smaller, less light gets through.
But aperture doesn’t just affect the brightness of your photos. It also impacts the depth of field – or how much of your photo is in focus. In doll photography, this means you can use aperture to blur the background, making your doll the center of attention.
The setting of your aperture is marked with an “f” on your camera.

How Aperture Affects Exposure (Brightness)
Aperture directly influences the exposure of your photo – in other words, how bright or dark the image looks.
- A large aperture (small f-number like f/1.8) lets in more light, making your photo brighter.
- A small aperture (large f-number like f/16) lets in less light, making your photo darker.
This is why, when you’re shooting indoors or in dim lighting, you may want to open up your aperture to allow more light in.
Fun Fact: Did you know that the word “aperture” comes from the Latin word apertura, meaning “an opening”? Think of it like the pupil of your eye – it gets bigger in the dark to let in more light and smaller in bright conditions!
Aperture and Depth of Field (Focus)

Now, here’s where things get interesting: aperture also affects depth of field – the amount of your photo that is in focus.
- A wide aperture (small f-number like f/1.8 or f/2.8) creates a shallow depth of field, which means only a small part of the image will be in focus (typically your subject, like your doll), and the rest of the background will be blurred.
- A small aperture (large f-number like f/11 or f/16) creates a deep depth of field, where more of the image, from the foreground to the background, will be in focus.
For doll photography, a wide aperture is often used to make the doll pop against a blurry background, creating that dreamy, professional look. in.
Aperture and Bokeh: The Beautiful Blur

When you use a wide aperture, something magical happens: the background becomes blurry, creating what’s called bokeh. Bokeh is the aesthetic quality of the blur in your photo, and it’s something many photographers aim for, especially in portrait or doll photography.
To see the effects of bokeh, take a close-up photo of your doll with a wide aperture, and notice how the background becomes soft and out of focus. This helps draw attention to your doll and keeps the focus on her details.
Distance Matters: How to Control Bokeh and Focus
You may have noticed that distance plays an important role in how aperture affects your photos. Here’s a helpful tip:
- The closer your camera is to your subject (your doll), the more pronounced the background blur will be – even with a smaller aperture setting.
- The farther away your subject is from the background, the more blurred the background will appear.
For example, if you place your doll close to the camera and the background farther away, you’ll create a stronger blur effect with a wide aperture. This is perfect for those stunning close-up shots where your doll’s expression is the star!

Practical Example
Using Aperture in Doll Photography


Getting hands-on experience with aperture doesn’t have to be complicated! Here’s a simplified experiment to help you see the magic of aperture without getting bogged down in manual settings:
What You’ll Need:
- Your camera or smartphone (yes, many phones have “Portrait Mode” that mimics aperture effects!)
- A doll or object to photograph.
- A background with some texture, like bookshelves, trees, or fairy lights.
Step-by-Step Experiment:
- Use Portrait Mode (for Phones):
- On most smartphones, switch to “Portrait Mode.” This mode automatically uses a wide aperture effect to blur the background. Take a photo and notice how the doll pops against the softened background.
- Use Auto Mode (for Cameras):
- Set your camera to its automatic or aperture-priority mode (often labeled “A” or “Av”). This way, the camera adjusts ISO and shutter speed for you.
- Take a photo with a wide aperture (lower f-number like f/2.8).
- Next, change the aperture to a higher number (e.g., f/11) and take another shot.
- Compare Your Shots:
- Look at the two photos side by side. In the first shot, the background will be beautifully blurred, while the second shot will show more background detail.
This experiment demonstrates how aperture affects both focus and depth of field. It’s also an easy way to see how aperture impacts the “mood” of your image, giving you more creative control.
Bonus Tip for Beginners: If you’re struggling with settings, many beginner cameras have a “depth of field preview” button or an on-screen simulation. Try using this to preview how aperture changes your shot before you take it!
Take your time and get to know your camera! Take a look where different options are. Where you can change your settings and what possibilities your camera has to make your time taking pictures a lot easier.
Aperture Is Your Creative Tool
Aperture isn’t just a technical setting on your camera – it’s a powerful creative tool. By understanding how aperture works, you can control how light enters your camera and how much of your photo is in focus. Whether you want a sharp image with lots of details or a soft, blurred background that draws attention to your doll, aperture is the key to getting that perfect shot.
Bonus Tip: These concepts are just the basics of aperture. If you want to learn more, there are plenty of detailed guides and tutorials online that can dive deeper into the topic. Aperture is a great place to start, but once you understand it, you’ll be able to explore other advanced settings to further enhance your doll photography!
I hope this guide helps you feel more confident using aperture in your doll photography! Have fun experimenting with different settings, and don’t be afraid to play around with the depth of field to create your own unique style. Happy shooting! 📸
