A marker can look tilted when the camera is above the dial axis. What extra image would separate perspective from an assembly issue?
Discussion record: RWF-27733.
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Request a level straight-on image with the hands…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
Request a level straight-on image with the hands clear of the marker. Compare two independently aligned images before drawing a conclusion; an overlay cannot correct an oblique camera angle.
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
