In this blog, we’ll dig into the world of forensic photography, exploring the techniques employed and the best practices that can ensure the reliability and integrity of evidence.

Introduction to Forensic Photography:

Forensic photography involves the systematic and detailed documentation of crime scenes, evidences and physical injuries using the specialized techniques. The primary objective is to create visual records that accurately and precisely represents the condition of the crime scene, preserving details that may be crucial for the investigations and legal proceedings. 

Purpose of Forensic photography:

Evidentiary Value

Forensic photographs serve as crucial evidence in court, providing a visual representation of crime scenes and supporting the investigation process.

Crime Scene Reconstruction

Forensic photographs aid investigators in reconstructing the sequence of events, spatial relationships and overall context of the crime. 

Documentation of Evidence

Photographs properly document physical evidence such as bloodstains, fingerprints, etc. helping maintain a detailed record for analysis.

Techniques in Forensic Photography

Forensic photographers use a variety of techniques to capture images that accurately represent the crime scene and evidence within it. These techniques are adopted based on the nature of the crime, type of the evidence and condition of the crime scene. 

List of the Techniques

Overview Photography

Capture wide angle shots of the entire crime scene to provide context and establish the overall layout of the scene.

Mid-Range Photography

Focuses on the specific area of interest, such as individual pieces of evidence to provide the detailed image for analysis.

Close-up Photography

Capture extreme close-ups of specific pieces of evidence to record minute details like tool marks, shoe impressions, biological evidence, etc.

Specialized Lighting Techniques

Use various lighting techniques including oblique light and alternate light sources, to enhance visibility and reveal details that might not be visible under normal lighting conditions.

Infrared Photography

Infrared photography captures details that might not be visible to the naked eye such as latent fingerprints or bloodstains.

Crime Scene Photography

360 Degree Photography

Use a systematic approach to capture photographs from all angles, ensuring a detailed and comprehensive documentation of the crime scene.


Photogrammetric techniques create three dimensional models of the crime scene, allowing for accurate measurements and reconstructions.

Scale Photography

Include scales or reference markers in photographs to provide a means of measurement for further analysis.

Sequential Photography 

Capture photographs sequentially to document the evolution of an investigation, from the initial state of crime scene to the completion of evidence collection.

Evidence-Specific Techniques

Blood-stain pattern Photography

Use special lighting and filters to capture bloodstain patterns, providing the crucial information about the nature of crime. 

Footwear and Type impressions Photography

Use oblique lighting and casting techniques to capture detailed images of footwear and tyre impressions, aiding in their analysis and comparison.

Firearm and Toolmark Photography

Use macro photography to capture details of firearm markings and toolmarks, providing evidence for ballistic and toolmark analysis.
