What needs to be clarified
Assess suitability and grounds for comparing visible features using documented recording conditions rather than an assumed mirror effect.
Materials to prepare
- The original recording showing the disputed image in context.
- Reference photographs of known provenance at available quality.
- Information on the camera, export and known file transformations.
What to compare
- Check the selected frame against the original recording sequence.
- Establish whether the materials support the image orientation.
- Separate appearance features from reflection and missing detail.
Possible outcome of the analysis
An opinion may define the available comparison and any separate technical clarification needed before addressing identity.
Limits of the conclusions
Unknown orientation cannot be replaced by guesswork; portrait examination does not guarantee identification from every reflected or poor-quality image.
