By ImgHeal · Updated
Compare age, angle, lighting, and provenance before using another photograph to judge a damaged face, garment, building, or object.

State the question it can answer
Identify whether the reference concerns face shape, garment color, an inscription, or a building feature. A source useful for one purpose may be weak for another. Record how the subject match is established. Similarity alone does not prove that an unidentified portrait shows the same person, even when the family relationship seems plausible.
Check important differences
Compare age, pose, expression, perspective, and lighting. A younger frontal portrait cannot establish the exact expression in a later profile. Another restored image may already contain generated details. Prefer a clearly sourced original where available and keep uncertainty visible when the comparison depends on an interpretation rather than an untouched photographic reference.
Keep the exposure as the record
Use the damaged source as the primary evidence of this particular photograph. References can help detect likeness errors, but copying features creates a composite decision that should be documented. Save reference provenance with the project. Do not present newly constructed detail as something revealed within the damaged original when it came from another image.
Check before finishing
- The reference answers a defined question.
- Pose and age differences are considered.
- Borrowed detail is documented as reconstruction.
