Part of Unit: Forensic Science
Lesson Plan Overview / Details
Each crime scene has unique characteristics and the type of photographs necessary will be determined at the scene by the investigator.
A picture does tell the viewer many stories. The pictures you take will be submitted into court as evidence along with your testimony which will become trial records. These records will be maintained for future investigations as well.

Students will be able to use proper lighting and exposure in dark lighted areas and rooms. Students will know how to process the pictures to present as evidence in court.
Activities in this Lesson
- The Digital Camera - Hooks / Set
Introduction to all the basics of digital cameras.The digital camera works like the human eye: it captures waves of light through the opening of an aperture and projects them on the camera's sensor. This sensor converts light into electrons that are send to the processing unit and converts the image into pixels (short for picture cells).
- Introduction to Police Photography - Lecture
Teacher lead power point presentation on Police & Crime Scene Photography. The first known use of the camera for law enforcement purposes was in the mid 19th century, initially to record still images of arrested individuals and to document crime scenes.
This is still important today, but police also now use camera and video to record interrogations, traffic stops, surveillance, public thoroughfares, and traffic accidents. They also frequently use cameras to document physical evidence at a crime scene before it is collected into evidence. Fingerprints developed with fluorescent powder or illuminated by an alternate light source ( ALS, an intense light source with filters capable of illuminating a wide range of wavelengths from the short-wave ultraviolet (230nm) through the near infrared (900nm), commonly used to search for trace evidence at a crime scene) is an example of this.
The police photographer must have an understanding of how the camera can record not only the visual and audio components of an interrogation or traffic stop but also how it can record images at invisible ultraviolet (UV) and infrared (IR) wavelengths. The police photographer must also have a good working knowledge of other specialized techniques such as close-up (macro) photographs, the effective use of fill-flash and bounce flash, and photography in less than desirable conditions such as night-time with limited ambient lighting.

- Photography Scavenger Hunt - Lab / Shop
All students should have cameras for the scavenger hunts. If there is not enough cameras for the entire class, provide enough cameras for group work. Then split the group into teams, give them the list, set a meet back time and let them go. Encourage creativity and thinking outside the box for some of these clues and feel free to assign points to them as well to make it a competitive hunt if you so desire.

- Camera Lighting - Demo / Modeling
Digital camera lighting modes include manual and custom for complex lighting situations. Lighting techniques in crime scene photography can range from using hot lights, strobes, direct sunlight, diffused light, bounced light and a variety of other experimental methods. Students play with different lighting techniques for photography with information from a professional.
