How is authenticity established for photographs or videos?

• A. Through testimony or evidence showing it is a fair and accurate representation
• B. It is never necessary to authenticate photos
• C. By the photographer's memory
• D. By the date shot, alone

Answer: (A)

Authenticity is proven by showing that the photograph or video is a fair and accurate representation of what it claims to show. In practice, this means presenting evidence that the image came from the claimed photographer, at the claimed time and place, and that it has not been misleadingly altered. Typical ways to establish this include testimony from the photographer or someone with direct knowledge of how the image was created and preserved, evidence of a reliable chain of custody for the file, and metadata or other records that support the origin and integrity of the image. If needed, experts can analyze signs of editing or tampering. Relying on the date alone isn’t enough, and a photographer’s memory isn’t reliable by itself, so authentication usually requires corroborating proof that the image truly represents what it purports to depict.
