What is the minimum number of photos recommended for a photo array?

The recommendation for using a minimum of six photos in a photo array stems from the need to ensure a fair and effective identification process. Having at least six images provides a sufficient variety to avoid overwhelming the witness while also helping to prevent the chance of misidentification due to familiarity with a specific individual.

A six-photo array allows for the inclusion of both the suspect and non-suspect individuals, making it less likely that the witness will focus exclusively on one person, thus supporting the integrity of the identification process. This larger number helps to balance the potential for recognition and the complexities of eyewitness memory, ensuring a more reliable outcome.

Variations in recommended photo array sizes can lead to issues such as suggestiveness or bias, which is why guidelines often suggest six as a minimum standard to enhance the reliability of witness identifications.
