Focal refers to the central point of interest or activity in a particular context. In photography, for example, the focal point is the area of the image that draws the viewer's attention, often achieved through techniques like depth of field. In optics, focal length describes the distance between the lens and the image sensor, influencing how zoomed in or out an image appears. In a broader sense, focal can also relate to focus in discussions or projects, indicating the main theme or goal. For instance, in a business meeting, the focal topic might be strategic planning, guiding the conversation and decision-making process.
