Why is a scale included in forensic photographs ?
Answer: D
A scale is included to show the size of objects in the photo.
Forensic photographs of evidence such as wounds, footprints, fingerprints or tool marks are taken first without and then with a scale placed beside the object on the same plane. The scale allows the image to be printed at life size (1:1) and lets measurements be taken from the photograph for comparison.
Visual interest and composition are artistic concerns, not forensic ones, and the scale says nothing about time; the time is recorded in the photo log and the camera's metadata.
