Architectural and Interior Photography

When you tilt a camera upward to photograph a building, parallel vertical lines converge toward the top—the 'falling backward' effect. A tilt-shift lens physically shifts the lens plane to correct this optically. Without one, post-processing in Lightroom's Transform panel or Photoshop's Perspective Warp can digitally correct convergence, though this crops the image. The simplest prevention is distance: the farther you stand from a building and the more level your camera, the less convergence occurs. Wide-angle lenses exaggerate convergence; longer focal lengths minimize it.
