What two factors determine the usefulness of photographic evidence in investigations?

The usefulness of photographic evidence in investigations is primarily determined by its quality and admissibility. Quality refers to the clarity, resolution, and accuracy of the image captured. High-quality images can effectively convey critical details that may be relevant to an investigation, making it easier for investigators, jurors, or other stakeholders to analyze the scene or evidence being presented.

Admissibility is a crucial legal factor, as it pertains to whether the photographic evidence can be used in a court of law. For photos to be admissible, they must meet specific legal standards and protocols. This includes being relevant to the case, properly authenticated, and not prejudicial. If the evidence does not meet these standards, even high-quality images could be of little use in an investigative or legal context.

The combination of these two factors ensures that the photographic evidence not only provides a clear representation of the scene but also stands up to legal scrutiny, allowing it to be effectively utilized in the investigative process.
