According to Kevin Pritchard, he stated forensic technicians always photograph items of evidence as oppose to scenery. This is the first step in documenting a crime scene. Before retrieval of any evidence, it's important to capture the overall shots of the scene, midrange images to show relationships between objects, close ups of specific evidence (and the use of scales if appropriate). As mentioned in the Crime Scene Investigation Guide, Section D, the sketching process includes the following a title block, legend, directional indicators, and accurate measurements between objects and evidence. It is important to accurately record the crime scene like patters of blood splatter where spatial dimensions and trajectories can be critical to a scene.

Crime scenes are mostly different but few things that can repeat in crime scenes are bloodstain patterns this helps determine how someone was killed and the direction of the track. Impressions of footprint found in blood, firearms and tool marks that may be used require close up photographs in high resolution and very detailed notes to document the details. Another important method in crime scenes is fingerprint documentation, DNA does not lie and this type of analysis requires more specialized photography and knowing the lifting techniques to capturing fingerprints.

The type and how fragile evidence is, conditions of an environment as well as the reconstructive needs for courtroom presentation are methods in how documentation is used.

In order for the documentation of evidence to be held up in court is the accuracy of the evidence that was collected, in Crime Scene Investigation Guide- Section D, express that inaccuracies can lead to evidence being excluded which can really be harmful to a case. The evidence must be relevant to the facts of the case, It is vital that the logging of the crime scene was completed accurately of every person that handled the evidence or were involved in the crime scene MUST be recorded. Lastly but most importantly, the technician who handled the documentation of evidence must be available to testify their findings to help in a case. (Films On Demand, 2025)
