Scales, Numbering and Directional Devices

Steven Staggs

Scales and measuring devices

Scales and measuring devices are frequently used in crime scene and evidence photographs. While they are sometime used to orient the viewer of the photograph to the relative size of the object in the photograph, scales are primarily used to serve as a basis for making enlargements to a specified magnification level, such as life size. This is critical for photographs of evidence that later will become the basis for a comparison—such as a photograph of a footwear impression that will be compared with the shoe of a suspect—since a photograph must be printed to life size. A variety of scales must be available for photographing different types of subjects.

  • Small self-adhesive scales are used to photograph evidence such as fingerprints and bullet holes in walls.

  • 6 inch scales are used for photographing most small to medium sized evidence. Some 6 inch scales have small numbers for extreme close-up photographs and others have large numbers for photographing larger items. The larger numbers allow easy reading of the scale from a greater distance.

  • Large "L" shaped scales are frequently used for photographing footwear impression evidence while small "L" shaped scales are used for photographing injuries such as bruises and bite marks.

  • Longer scales with large, easy to read numbers are used for photographing tire tread impressions and bloodstain scenes. These long scales can be metal or cloth tape measures or plastic scales.

When using scales in photographs, two photographs of each item of evidence must be taken. One photograph must be taken without the scale in view and one photograph taken with the scale. The first photograph will document that the photographer did not cover or block other evidence with the scale.

Numbering and directional devices

Numbering devices are commonly used to identify similar appearing evidence. For example, several bullet holes in a wall would need to be individually numbered. It is usually unnecessary to place numbering devices in a photograph to identify items of evidence that cannot be confused with other items.

This Month's Featured Resource on the Crime Scene Investigator Network Website

Just as today's law enforcement officer has learned to look routinely for fingerprints to identify the perpetrator of a crime, that same officer needs to think routinely about evidence that may contain DNA. Recent advancements in DNA technology are enabling law enforcement officers to solve cases previously thought to be unsolvable. Today, investigators with a fundamental knowledge of how to identify, preserve, and collect DNA evidence properly can solve cases in ways previously seen only on television. Evidence invisible to the naked eye can be the key to solving a residential burglary, sexual assault, or child's murder. It also can be the evidence that links different crime scenes to each other in a small town, within a single State, or even across the Nation.
