Fig. 124: Landscape, portrait, and square format images of a single subject 3.7 Image Formats The image format you use can have a significant influence on the way an im- age is perceived. Landscape format is the most commonly used in architec- tural photos, as it most closely represents the way we see our surroundings. Portrait format images are used less often, while a square format (fig. 124) is calmer, and emphasizes neither the vertical nor the horizontal dimension.
