The huge red explosive cloud is the focal point of this photo. The red color symbolizes the dangerous nature of drugs to human and the dangerous situation of explosion in the picture, which acts as a reminder to hope people keeping themselves away from drugs. The object in this photo is asymmetrical, because the explosion cloud occupies two-third of the photo so as to emphasize the explosion. No framing is used because explosion would not be limited in a certain place. The sharp image of the man creates a second focus for the photo. To capture his motion of running away, the angel of photo taking is from the front view horizontally. For the lighting and texture, the background house is blurred so the explosion cloud can be emphasized. The lighting is relatively artificial in order to capture and visualize the red color of explosion cloud. All of the above contribute to the significance of the photo, which is the dangerous nature of drugs. Harmful drugs have to be destroyed and illicit trafficking has to be banned.
