tredjedelsregelen

Tredjedelsregelen, known in English as the rule of thirds, is a guideline used in visual composition across photography, film, painting, and design. It proposes dividing the frame into nine equal parts by placing two equally spaced vertical lines and two equally spaced horizontal lines. The idea is to position key elements along these lines or at their intersections rather than directly in the center.

The rule aims to create balance, tension, and visual interest. Placing a subject off-center can produce a more dynamic image and help guide the viewer’s eye through the composition. Common practices include aligning horizons with the upper or lower horizontal line and placing important features at or near the intersection points of the grid.

Applications of the rule of thirds span multiple media. In photography and film, it is frequently taught as a practical tool for composing portraits, landscapes, and architectural shots. In painting and graphic design, it serves as a heuristic to structure space and prioritize focal points. Modern cameras often provide a rule-of-thirds overlay in the viewfinder or on-screen display to aid adherence.

While widely taught, the rule of thirds is not a universal law. It is a compositional aid that can be deliberately ignored or subverted for artistic effect. In some situations, centered or other unconventional compositions better convey mood or emphasis, depending on the subject and desired impact.

The term tredjedelsregelen reflects a broader set of guidelines used in Western visual arts to foster balance and viewer engagement, with variations across styles and media.
