The field of view refers to the amount of the scene that a camera lens can capture. A wider field of view will include more of the surrounding environment in the frame, while a narrower field of view will focus on a smaller area with greater detail.
In photography and videography, the field of view directly affects the composition of the image or video. A wider field of view can create a sense of expansiveness and openness, making the viewer feel immersed in the scene. This can be useful for capturing landscapes, architecture, and group shots where you want to include more elements in the frame.
On the other hand, a narrower field of view can isolate the subject and bring attention to specific details. This can be effective for portrait photography or close-up shots where you want to emphasize the subject and minimize distractions in the background.
When using a smartphone camera with different field of view options, such as wide-angle or telephoto lenses, it's important to consider how the chosen field of view will impact the composition of the photo or video. Experimenting with different perspectives can help you create more dynamic and visually appealing shots.
