What is a 360 Camera?
The short answer is this: a 360 camera shoots in all directions at once. Imagine a sphere with a picture stretched out across it. You can choose any square on that sphere and use it for your final video or photo. This opens up numerous editing options, which we’ll explore later. You can also use the 360 footage directly, as people do for virtual reality.
How Does a 360 Camera Work?
A 360 camera works by using two or more lenses to capture a 360° view. It’s like having multiple cameras in one device. The camera blends the images to form a complete 360° sphere. For instance, the Insta360 X4 has two lenses that capture over 180° each, and then it stitches the images together where they overlap. This process allows for high-quality, seamless video or photos.
Using the Insta360 X4
Now that you understand how a 360 camera works, let’s dive into the specifics of using one, particularly the Insta360 X4.
Ease of Use
Using a 360 camera like the Insta360 X4 is incredibly easy. You don’t need any technical skills to capture footage. Simply press the shutter button as you would with any other camera. It automatically shoots in all directions. You can then edit the 360 video on your phone and export the footage as a traditional photo or video format, perfect for sharing on social media. You can also use the 360 video as is or export it as an equirectangular image.

What is an Equirectangular Image?
What is an Equirectangular Image?
An equirectangular projection might sound complicated, but it’s actually a concept most people are familiar with through the map of the world. Let’s break it down further.
The Basics of Equirectangular Projection
Equirectangular Projection Defined:
In cartography, an equirectangular projection is a method of mapping a sphere onto a rectangle. This is achieved by taking the spherical surface and stretching it out into a flat, rectangular shape. In simpler terms, it’s a way to represent every point on a sphere in a two-dimensional image. When you see a world map, you’re looking at an equirectangular projection of Earth.
Applying This to 360 Cameras:
The same principle applies to a 360 camera’s equirectangular image. When a 360 camera captures footage, it essentially takes a panoramic shot of everything around it, forming a complete sphere of visual data. This sphere is then converted into a rectangular image using equirectangular projection. This allows you to view and edit the entire 360° field of vision on a flat surface, such as a computer screen or a smartphone display.
Visualizing Equirectangular Projection
Imagine the World Map:
To better visualize this, think about a globe and a world map. A globe represents Earth accurately as a sphere, with every point on its surface maintaining its true spatial relationships. However, when we create a map of the world, we have to stretch and distort this spherical surface to fit it onto a flat piece of paper.
Despite the distortions, we can still identify continents, countries, and oceans. Similarly, an equirectangular image from a 360 camera represents the entire 360° view in a flat, rectangular format.
Understanding the Distortion:
Just like the world map, an equirectangular image has distortions, particularly at the top and bottom edges (near the poles on a world map, or the top and bottom of the 360° sphere). These distortions are a result of trying to represent a spherical surface on a flat plane. Despite this, equirectangular images are highly useful for editing and viewing 360° footage.
Why Use a 360 Camera?
360 cameras are a game changer compared to regular cameras. Let’s explore some key benefits.
Reframing
One of the best features of 360 cameras is the ability to reframe your footage. You can take your 360° video and create regular rectangular videos that focus on the best parts. This means you don’t need to aim the camera perfectly while shooting.
You can also show multiple views in one video by switching the camera direction during editing. Reframing is particularly useful for sharing videos on social media, where different platforms prefer different aspect ratios, such as 9:16 for TikTok and Reels, 1:1 for Instagram or Facebook, and 16:9 for YouTube. The Insta360 app makes framing all of these a breeze.
Invisible Selfie Stick
Another cool feature of the Insta360 X4 is the invisible selfie stick. This tool allows you to capture creative angles and shots, such as third-person views or fake drone shots, without actually using a drone. The stick becomes invisible because it falls in the overlap between the two lenses and is automatically edited out of the shot.
Single Lens Mode
A 360 camera like the X4 can also double as a regular single-lens camera. The Insta360 X4 offers a 4K single lens mode, which captures traditional rectangular footage, just like a regular action camera. This mode is great for point-of-view shots.
Editing 360 Footage
Editing 360 footage might seem challenging, but with the Insta360 app, it’s straightforward. You can easily edit your footage on your phone. Whether you’re using the viewfinder to aim your phone and reframe, or simply swiping and placing keyframes, editing 360 footage is simple.
There’s even a “Me Mode” feature that focuses on you the whole time while capturing, meaning you don’t need to aim or edit either. Additionally, you can explore Shot Lab for cool effects on your footage.

Is a 360 Camera Worth It?
360 cameras can seem daunting at first, but they’re actually very user-friendly. Cameras like the Insta360 X4 come with a variety of features that are impossible to achieve with traditional cameras. With the Insta360 app, even a beginner can edit 360° footage like a pro.
Practical Applications of 360 Cameras
Now that we’ve covered the basics, let’s explore some practical applications of 360 cameras.
Travel Vlogging
