Perspective control refers to techniques used in photography and architecture to manage the way objects appear in relation to one another in a scene. This involves adjusting the camera angle, lens choice, or the position of the subject to create a desired visual effect. By manipulating perspective, photographers and designers can emphasize certain elements or create a sense of depth. In architectural photography, perspective control is crucial for accurately representing buildings and spaces. Techniques such as using a tilt-shift lens allow for correction of distortion that can occur when capturing tall structures, ensuring that lines remain straight and proportions appear natural. This helps convey the true essence of the design of structures like skyscrapers or historical buildings.
