Lighting is a key element of photography as it allows the recording of light rays. Choosing lighting carefully is important for good pictures. Composition refers to combining different elements in a photo to create a whole image. Considering aspects like the subject, lighting, and framing can improve composition. Depth of field is the zone of sharpest focus around the focused subject and is influenced by factors like camera distance and lens settings. A focal point is the central element of interest that draws the viewer's eye to a certain part of the photo.
