Imagine that you have just been called to the scene of a car accident which appears to be the result of drunk driving. all persons involved have been transported to the hospital, and now it is your job to document the scene. write a short log of your experience at the crime scene as if you were the crime scene photographer. use your imagination about the details of the scene, and discuss eight photographs you could take (make sure you are including photos from each of the three categories – overview, mid-range and close-up). for each, include details such as a date, time, locations, objects, angles of photographs you took, etc.
