Among the azimuth-and-outline photographing technology for scene investigation of road traffic accident, both the rotary continuous photographing and straight-line consecutive one are the best shooting approaches to either reflect the full view of accident scene or present the relationship between the main body of accident and the various traces of physical evidence. By analyzing such problems as the cumbersome operational procedures, high requirements, time-consuming and the other related that exist in the practical photographing with the above two methods, this essay puts forward that the azimuth-and-outline photography can be optimized with either one panoramic camera or a mobile phone's function of taking whole scene. Additionally, the likely emerging problems are analyzed of their solutions, together with an exploration of the relevant standards and norms about specification for selected forensic photographing equipment. Accordingly, the modification advice has been suggested for the rules on “technical requirements of forensic photographing equipment”, “photography for scene investigation” and “photographing for road traffic accident scene”.
