Equally important is the choice of lens. While wide-angle lenses are the standard for capturing expansive interiors or towering skyscrapers, they often introduce distortion, causing vertical lines to converge. To combat this, professionals often rely on tilt-shift lenses. These specialized lenses allow the photographer to physically shift the lens plane relative to the sensor, keeping vertical lines perfectly straight without having to angle the camera upward. This technique is essential for avoiding the "falling backward" look that plagues amateur architectural shots.
