Separate the causes
Unknown scale
Include a physical scale in the same plane as the feature; digital zoom alone is not a measurement.
Different lighting
Compare reference and affected samples under the same viewing setup, particularly for shade and nap.
Unknown location
Map the feature to roll and metre position so the supplier can find its counterpart.
Steps before deciding
- Keep unedited original files with date and case identity.
- Take overview, location and detail views.
- Record actual measurements separately from images.
- Retain the physical sample with face and direction marks.
- State observed facts rather than attaching an unsupported cause label.
Worked example
Hypothetical example: two phone photos use different white balance. They can show that a concern exists but cannot alone quantify the shade difference.
Buyer questions
Should I enhance contrast?
Keep originals and disclose edits; enhancement changes appearance.
Can photos replace a returned sample?
Only within the agreed evidence scope, not for every physical property.

Reference and limits
The reference identifies Fred Textile’s manufacturing operations. The workflows are editorial buyer guidance, not laboratory procedures or product certification. Numerical examples are hypothetical and do not create acceptance limits. Agree the actual order and test basis before deciding.
