What should be done to document known evidence items during a photography session?

Using placards sequentially to differentiate items is essential in a photography session for documenting known evidence items. This method helps provide clarity and organization to the visual records, ensuring that each piece of evidence is clearly identified and can be referenced accurately later.

Placards serve as identifiers for each item, allowing investigators and other parties reviewing the photographs to connect the visual evidence with specific details, such as case numbers, item descriptions, or even the sequence of discovery. By capturing these placards with the items, it reduces the risk of confusion and erroneous interpretations of the evidence.

This systematic approach also aligns with best practices in forensic photography, where maintaining a clear chain of evidence is crucial for legal proceedings. Properly documenting evidence in an organized manner helps support the integrity of the investigation and ensures that all relevant information is available for analysis.
