What most agencies fail to realize is that the lack of SOPs involving digital image integrity and workflow means images submitted for court purposes may not survive if challenged by a knowledgeable attorney. These digital complexities have not yet been realized, so images taken by photographers will likely fail one of three very basic criteria:

1. The date and time setting in the camera is incorrect.
2. The wrong lens focal length was used, resulting in an inaccurate depiction of the scene.
3. Embedded information may indicate the image has been modified.
