These visual aids are overlays displayed on a mobile device’s camera viewfinder. These lines assist in composition, providing reference points based on principles like the rule of thirds, which suggests placing key elements along these lines or at their intersections for more visually appealing photographs. An example includes configuring the camera application on an Android phone to show a 3×3 grid, dividing the screen into nine equal rectangles.
The presence of these guidelines enhances photographic and videographic results by promoting balanced framing, straighter horizons, and better subject placement. Their implementation reflects a consideration of established artistic principles within mobile photography, allowing users to more easily apply techniques that were traditionally associated with professional photography. This feature democratizes access to compositional tools, extending them to a broader audience.
