Photography is a subject where you can easily get lost in jargon and technicalities. But some of the concepts are fundamental to understanding how a camera works. One such concept is Field Of View or FOV for short.

In this guide, I will demystify the concept of Field Of View and how it differs for various lenses, cameras, formats, and distances. All this will be illustrated using video tutorials throughout.

The first question you might ask is why Field Of View is important. Well, in terms of photography it describes the amount of scene captured by the camera.

This is important because to some extent it determines what we can see in a photo. A camera with a very small FOV will only capture a small part of the total scene, so we won’t get to see much.

On the other hand, a camera with a very large FOV can capture almost everything, so we’ll be able to see a lot more details and relationships within that scene.

What Is field of view (FOV)?

Field of view is a measurement of the area that a camera lens or eyepiece takes in at one time and is expressed in degrees. This may be known as angle of view or panoramic viewing angle.

Taken from the context of telescopes, it refers to the size of the image captured by an instrument’s optics.

The field of view is also dependent on the magnification power of the instrument since this has a direct effect on the angle at which an object appears to be viewed.

 

Understanding Field of View: Impact on Gaming & VR

When we talk about the field of view (FOV), we’re diving into one of the most crucial aspects that determine how we perceive the world through various lenses.

It’s the extent of the observable world that’s seen at any given moment, and it can make or break the effectiveness of everything from binoculars to video games.

Understanding FOV is essential, whether you’re snapping the perfect photo or immersing yourself in a virtual reality experience.

We’ll explore how field of view impacts our visual perception and why it’s a key player in different technologies and applications.

   

Stick with us to unlock the secrets of FOV and how it shapes our interaction with the world around us.

What Is Field Of View?

Understanding field of view (FOV) is crucial in filmmaking and a foundational concept in visual storytelling.

It’s the extent of the observable environment seen at any given time through the lens of a camera.

In filmmaking, different lenses offer varying degrees of FOV.

Wide-angle lenses capture a broad vista, immersing the audience in the setting while telephoto lenses provide a narrow FOV, focusing on specific details or subjects.

The choice of FOV can dramatically alter the narrative tone of a scene.

The Grand Budapest Hotel utilizes a wider FOV to showcase its exquisite set design whereas The Revenant uses it to envelop the viewer in vast, untouched landscapes.

But, FOV isn’t just about the width of the shot.

It’s also about the viewer’s perception of depth and scale within the frame.

This affects how characters and objects are situated in relation to each other and their surroundings.

In video games, FOV settings can be adjusted to the player’s preference.

This personalization allows for an enhanced gaming experience, tailored to individual comfort or gameplay style.

Crafting a scene with the right FOV requires an understanding of:

  • Spatial relationships in the narrative,
  • Emotional impact of different FOV settings,
  • Technical capabilities of the camera equipment.

Selecting the optimal FOV is a nuanced decision that can elevate the storytelling impact of a film.

   

It’s a critical tool in our arsenal as filmmakers, influencing how audiences connect with the visual narrative.

The Importance Of Field Of View In Perception

Field of view isn’t just a technical feature; it’s a storytelling powerhouse.

In filmmaking, subtle changes in FOV can make a scene feel intimate or expansive, influencing our emotional response.

Wide FOVs immerse us in environments, while narrow ones focus our attention, often creating tension.

Directors and cinematographers choose specific FOVs to craft characters’ perspectives.

Think of Stanley Kubrick’s The Shining – wide angles made the Overlook Hotel feel menacingly vast.

In contrast, tight FOVs in Darren Aronofsky’s Requiem for a Dream trapped us within the characters’ personal hells.

Here are some FOV considerations:

  • Spatial awareness – wider angles give a sense of openness,
  • Emotional connection – tighter angles can heighten feelings of claustrophobia or intimacy,
  • Storytelling context – FOV can symbolize a character’s mindset or the overall theme.

The interplay of FOV and perception can’t be understated.

   

By manipulating FOV, we guide viewers through the storyline, controlling their sense of place and connection to the visual narrative.

Movies like Gravity use a varied FOV to simulate the vastness of space and the isolation of the protagonist.

Understanding FOV in terms of human perception leads to better appreciation of its impact in visual media.

It’s not just what you show, but how you show it – the FOV shapes our interpretation of the cinematic world we’re invited into.

As filmmakers, taking command of this powerful tool enables us to deliver more impactful and memorable stories.

How Field Of View Impacts Different Technologies

In the realm of virtual reality (VR), field of view is a make-or-break factor for user immersion.

A wide FOV in VR setups mimics the human eye, creating a more natural and engaging experience.
