Crime Scene 101: Locating and Documenting Evidence
By Dick Warrington
At the heart of every crime scene are two basic questions for the Crime Scene Officer: how do you find the evidence and how do you properly document it once you find it?
Film To Digital Conversion For Law Enforcement: An Update
By Steve Scarborough
An effective conversion from film to digital images requires more than a camera. A comprehensive digital imaging system is invaluable when storing, managing, and retrieving digital images.
High Definition Laser Scanning Takes Forensic Geosciences to a New Level
By Jacob Dabrowski
Using High Definition Laser Scanning, an entire crime scene can be thoroughly documented making it possible to revisit the scene as the evidence is analyzed.
Documenting Clothing in 3D
By Jon J. Nordby, Eugene Liscio
When inspecting clothing from a homicide case, it is usually necessary to measure where injuries may have occurred on the body. One means of recording the 3D positions of such clothing defects or marks on clothing involves using a 3D laser scanner. After putting the clothing on a mannequin, we use the laser to sweep through one side, creating a 3D mesh from the surface points.
A Primer on 3D Scanning in Forensics: Part 2
By Eugene Liscio
3D scanning for forensics is an ever growing and useful application of laser based measurement technologies in fighting crimes and reconstructing events. Like all forensic tools, however, 3D scanning has its strengths and its limitations.
A Primer on 3D Scanning in Forensics: Part 1
By Eugene Liscio
As 3D scanners become more common for capturing and preserving evidence, police, forensic technicians, and others involved in the field need to be aware of the applications, benefits, and limitations of this technology and how it can be used in the analysis of evidence and crime scenes.
Microsoft's Photosynth: A Future Forensic Tool?
By Eugene Liscio
First responders, forensic technicians, and investigators could quickly gather a large number of overlapping photographs without the need for special targets, expensive equipment, or complicated software, and then use Photosynth to find the common features between the photos and how each of the photos are oriented with respect to one another in 3D space.
Documenting Bloodstain Patterns Through Roadmapping
By Daniel R. Winterich
An accurate and methodical technique for documenting bloodstain patterns is invaluable in crime scene analysis.
Crime Scene Photography: Capturing the Scene
By Dick Warrington
In order to provide a complete record of each scene, you need field notes and diagrams, along with relevant still photographs that correlate with those notes and diagrams.
3D Scanning: A New Tool for Cracking Tough Cases
By Peter DeLaurentis
What do U.S. federal investigators and anthropologists at the Smithsonian Institute have in common? They are both pioneering the use of 3D scanning technology to solve challenging mysteries.
CSI Cameras of Today
By Caroleann Fusco
With rapid development in the technology field, it’s difficult for a forensic photographer to choose the right camera and equipment. I receive calls daily from forensic photographers in many fields wanting to know which camera can do it all.

Video Enhancement of Facial Images
By Barbara A. Martin Bailey
SOPs (Standard Operating Procedures) at many animal care facilities are only updated just prior to IACUC reviews or AAALAC inspections and are written from an administrative perspective rather than the perspective of the user.

Crime Scene 3D Viewpoints Illustrating What Was Seen at the Scene
By Doug Schiff
What exactly did you see as you walked through the door? Could you see into the next room? Where were you when you first saw the suspect standing at the window? Could you see a particular piece of evidence from that position? Could the suspect have seen into the hallway? Questions like these are often critical to understanding the development of events at a crime scene. What did you see and when did you see it? Answers to these questions must be clear and understandable.
Forensics Focuses on Digital Photography
By Douglas Page
There's good news and bad news: lower processing costs and diminishing film availability have driven forensic science toward digital photography.
Forensic Imaging Goes Digital
By Jason Schneider
Digital technology is putting crime labs on the fast track by making infrared and ultraviolet photography easier, quicker, and less expensive then ever before.
Film to Digital Conversion: Special Considerations for Larger Agencies
By Steve Scarborough
Photography has seen some dramatic changes over the years ever since the 1840’s when the advancement of acetate and gelatin for use as film made photography more practical.
