A wide-angle lens is a type of camera lens that has a shorter focal length than standard lenses, allowing it to capture a broader field of view. This wider perspective is particularly useful for landscape photography, architecture, and any situation where you want to include more of the scene in the frame. Wide-angle lenses exaggerate the sense of depth and distance between objects in the frame, which can create dynamic and impactful compositions. They are also commonly used in real estate photography and interior shots to capture more of the space in a single image.
