ABSTRACT
To freehand drawing, photography is a double-edged sword. The lens can make an exact copy of a building façade or city scene, allowing the designer to save time on the arduous task of rendering. Once a design has begun to take shape, photography can also allow the imagined object to be further explored with the help of digitisation. Hence, photography adds a useful dimension to the trilogy of freehand sketching, model-making and CAD simulation.
