látószög

Látószög, or field of view, refers to the extent of the observable world that is seen at any given moment. It is a fundamental concept in various fields such as optics, photography, and computer graphics. In human vision, the field of view is typically measured in degrees and can vary depending on the part of the eye being considered. The central part of the retina, known as the fovea, provides the sharpest vision and has a narrow field of view, while the peripheral vision covers a wider area but with less detail.

In photography and cinematography, the field of view is determined by the lens used and affects the composition of the image. A wide-angle lens provides a broader field of view, capturing more of the scene, while a telephoto lens offers a narrower field of view, magnifying a specific area. This concept is crucial for creating the desired perspective and focus in visual media.

In computer graphics and virtual reality, the field of view is a critical parameter that influences the immersive experience. A wider field of view can make virtual environments feel more expansive and realistic, while a narrower field of view can create a more focused and intimate experience. Developers often adjust the field of view to optimize user comfort and interaction within virtual spaces.

Understanding and manipulating the field of view is essential in various applications, from designing optical systems and capturing photographs to creating immersive digital experiences. Whether in natural or artificial environments, the field of view plays a pivotal role in how information is perceived and interpreted.
