What is Field of View (FOV)?
The field of view (FOV) is key in many areas, like photography, videography, gaming, and virtual reality. It’s the angle we see of a scene. This angle is measured in degrees and can be horizontal or vertical.
Understanding the Concept
Think about looking through a camera lens or your eyes. The area you see is your field of view. It shows how much of the world you can see at once. A wider FOV lets you see more, while a narrower one focuses on less.
Measuring Angles and Degrees
FOV is usually measured in degrees. Zero degrees is a single point, and 180 degrees is half a circle or half a sphere. For instance, a 60 degree FOV is 60 degrees wide. Knowing how to calculate vertical angles and the difference between horizontal and vertical FOV is vital.
| Angle | Description |
|---|---|
| 90 degrees vertical | This represents a vertical field of view that covers a complete half-sphere, from the horizon to directly overhead. |
| 60 degree FOV | A moderately wide field of view, often used in photography and videography. |
| 120 degree FOV | An extremely wide field of view, common in action cameras and virtual reality headsets. |
| Human eye FOV | The average human eye has a field of view of around 180-200 degrees horizontally and 130-150 degrees vertically. |
“Understanding the concept of FOV and how to measure angles in degrees is crucial for various applications, from photography and videography to gaming and virtual reality.”
Horizontal FOV Calculation
Calculating the horizontal field of view (FOV) is key for camera framing, lens choice, and virtual world design. It uses the sensor size and focal length. A simple formula helps find the horizontal FOV for any setup.
To find the horizontal FOV, you need the sensor size and the camera’s focal length. The formula is:
Horizontal FOV = 2 × arctan(sensor width / (2 × focal length))
Let’s look at the formula step by step:
- Sensor width: This is the camera’s image sensor width, in millimetres (mm).
- Focal length: This is the lens to sensor distance, also in millimetres (mm).
- arctan: This is the inverse tangent function, for angle calculation in radians.
With sensor width and focal length known, plug them into the formula. This will give you the horizontal FOV in degrees. This value shows the angle your camera or device captures.
For example, with a camera of 22.3 mm sensor width and 35 mm focal length, the calculation is:
Horizontal FOV = 2 × arctan(22.3 / (2 × 35)) = 63.4 degrees
Knowing how to calculate the horizontal FOV helps you set up your camera right. It lets you pick the best lens and ensure your shots have the right field of view.
Vertical FOV Calculation
Understanding the vertical field of view (FOV) is key to grasping what a camera or screen shows. Like the horizontal FOV, we can easily figure out the vertical FOV using a simple formula. This is especially vital in games like Helldivers 2, where a bigger vertical FOV makes the game feel more real and immersive.
Vertical to Horizontal FOV Conversion
Converting between vertical and horizontal FOV is sometimes needed. We can do this with a simple formula: vertical FOV = (vertical sensor size / horizontal sensor size) × horizontal FOV. For example, a camera with a 75% vertical FOV to horizontal FOV ratio means its vertical FOV is 75% of its horizontal FOV. On the other hand, a 70% ratio means the vertical FOV is 70% of the horizontal FOV.
Knowing the vertical to horizontal FOV formula helps photographers, videographers, and game developers tweak their settings. This is important for getting the right field of view, whether it’s for a broad landscape shot or a deep virtual reality dive. Learning how vertical FOV is calculated is essential in today’s visual media world.
The Importance of Sensor Size
The size of the sensor or display in an imaging system is key to understanding field of view (FOV). The sensor size affects the field of view. Knowing this is vital for choosing the right equipment and settings for different uses.
The sensor size, measured in millimetres (mm), affects the sensor size and the what is the best fov range?. Bigger sensors mean a wider field of view. Smaller sensors have a narrower field of view. This is especially important in photography, videography, and virtual reality.
| Sensor Size | Typical FOV Range |
|---|---|
| 1/2.3″ (6.17 x 4.55 mm) | 84° – 100° |
| 1″ (13.2 x 8.8 mm) | 70° – 90° |
| APS-C (22.2 x 14.8 mm) | 50° – 80° |
| Full Frame (36 x 24 mm) | 40° – 70° |
Understanding the link between sensor size and what is the best fov range? helps users choose the right gear and settings. This is true whether you’re capturing wide landscapes, close portraits, or immersive virtual reality scenes.
“The size of the sensor or display is a critical factor in determining the field of view, and understanding this relationship is essential for creating the desired visual experience.”
Focal Length and Its Role
Focal length is key in photography, videography, and more. It changes how much of the scene we see. This affects how big or small things look in our pictures.
Calculating Focal Length
To find a lens’s focal length, use this formula:
- Focal Length = Distance to Subject / (Sensor Size / Field of View)
- For example, if the subject is 10 metres away, the sensor is 24mm, and you want a 45° view, the focal length is about 50mm.
Understanding focal length helps when you need a field of view at 100x magnification or calculating your vertical field of view. It guides you in choosing the right lenses or setting up your camera for the look you want.
“Focal length is the distance from the optical centre of the lens to the image sensor or film plane when the lens is focused on an object at infinity.”
Learning about focal length opens up new creative options in your photography and videography.
Horizontal/Vertical FOV Calculation
To figure out how to calculate FOV, we look at sensor size, focal length, and the angles of view. This is key in photography and videography. It shows what area is captured in the frame.
Is FOV measured in degrees? Yes, FOV is indeed measured in degrees. The horizontal and vertical angles are the main metrics. The formulas to find these are simple and work for many camera and lens setups.
Calculating Horizontal FOV
The formula for horizontal FOV is:
Horizontal FOV = 2 × arctan(sensor width / (2 × focal length))
Just plug in the sensor width and focal length to find the horizontal angle of view in degrees.
Calculating Vertical FOV
The vertical FOV formula is similar, using the sensor height:
Vertical FOV = 2 × arctan(sensor height / (2 × focal length))
With these formulas, you can easily find the horizontal and vertical FOV for any camera and lens setup.
| Sensor Size | Focal Length | Horizontal FOV | Vertical FOV |
|---|---|---|---|
| APS-C (23.6 × 15.8 mm) | 50 mm | 39.6° | 26.6° |
| Full Frame (36 × 24 mm) | 50 mm | 46.8° | 31.1° |
| Micro Four Thirds (17.3 × 13 mm) | 25 mm | 47.3° | 35.6° |
Knowing these calculations helps you plan your camera framing and composition better. This ensures your images and videos capture the right field of view.
Applications in Photography and Videography
Knowing about horizontal and vertical field of view (FOV) is key in camera lens specifications. You can adjust camera settings and lens choices to get the right FOV for different shots. This includes landscapes, portraits, and action photos.
Camera Settings and FOV
The FOV shows how much of the scene your camera will capture. A wide FOV, like a 120-degree FOV on PS5, is great for landscapes and buildings. It lets you see more of what’s around you.
For portraits and wildlife, a narrower FOV is better. It helps you focus on your subject and make them the main focus.
To change the FOV, you can play with these settings:
- Focal length: A longer focal length lens gives you a narrower view. A wider angle lens shows more.
- Sensor size: Bigger camera sensors, like those in full-frame cameras, offer a wider FOV. Smaller sensors in compact or mirrorless cameras have a narrower view.
- Aspect ratio: Changing your camera’s aspect ratio (e.g., 4:3, 16:9, or 3:2) can also change the FOV and how your shots are framed.
By understanding camera lens specifications and how they affect the FOV, you can make better choices. This helps you get the look and feel you want in your photos or videos.

Comparing Human and Camera FOV
The human eye and camera lenses have different field of views (FOV). What is a normal person’s field of view? Humans can see about 180-200 degrees horizontally and 130-160 degrees vertically. This lets us see a wide view of our surroundings.
What is the vertical field of view of the human eye? Our vertical angle is about 90 degrees, not 180. This is because our eyes are set horizontally on our face. It gives us a wider horizontal view than a very wide vertical one.
How to do the vertical angle theorem? To find vertically opposite angles, just remember they are the same. These angles are made when two lines cross over. The angles directly across from each other are always the same.
| Characteristic | Human Eye | Camera Lens |
|---|---|---|
| Horizontal FOV | 180-200 degrees | Varies based on lens |
| Vertical FOV | 130-160 degrees | Varies based on lens |
| Vertical Angle | 90 degrees | Varies based on lens |
Are all vertical angles 360 degrees? No, vertical angles are usually 90 degrees, not 360. While all angles in a circle add up to 360 degrees, each vertical angle is 90 degrees.
“The human eye’s field of view is significantly wider than most camera lenses, allowing us to perceive our surroundings more naturally.”
