The short answer: photographs can reveal useful details, inconsistencies and missing evidence. They cannot reproduce every aspect of physical examination, establish provenance on their own or justify certainty when angles, resolution and lighting are inadequate.
Authentication is a conclusion from agreement#
A defensible assessment considers whether multiple kinds of evidence agree: construction, materials, dimensions, stitching, hardware, markings, production context, wear, repairs, provenance and the seller’s account. One code, card, stamp or receipt should never carry the whole conclusion.
What a useful image set includes#
Request sharp, neutral-light photographs of:
- Full front and rear.
- Both sides and base.
- Corners and edge finishing.
- Handles, straps and attachment points.
- Closure, zips and hardware from several angles.
- Interior, pockets and lining transitions.
- Relevant markings and identifiers in context.
- Included accessories.
- Any disclosed wear, repair or alteration.
Images should show the exact item currently offered. Stock photographs or highly compressed screenshots are not inspection evidence.
What photographs may conceal#
Colour can shift under warm light. Texture can disappear through compression. Odour, weight, sound, tactile quality and some internal construction cannot be judged reliably from a screen. Strategic angles can hide wear, repairs or proportion problems.
If the image set is inadequate, the correct outcome is “insufficient evidence,” not forced approval or rejection.
Identifiers need context#
Serial formats, date codes, chips, stamps and cards have changed across brands and time. Counterfeit items may copy plausible identifiers, while authentic older items may have wear or documentation gaps. Treat identifiers as contextual observations that must agree with the whole bag.
When to require physical specialist review#
Use an established independent specialist when the value is high, evidence is ambiguous, the source is unfamiliar or the transaction terms depend on an authenticity conclusion. Agree in writing on who selects and pays the specialist and what happens after an adverse or inconclusive result.
The language an advisor should use#
Responsible wording distinguishes between observation and conclusion:
- “The supplied images show…”
- “This detail is consistent/inconsistent with…”
- “The image quality does not allow…”
- “Physical inspection is recommended because…”
Absolute certainty from one photograph or identifier is a warning sign.
