The main objective is to record and graphically document evidence for legal purposes because it is an element of legal proof. Before taking a photograph, the photographer must analyze the scene and the elements needed in the shooting (e.g.: appropriate ISO, aperture, speed angle of view to avoid potential distortions of distance, lighting conditions, lens, etc.) in order to obtain the correct results.
