A join must remain visible
Separate securely joined fragments, fills, support and visual alignment instead of smoothing them into one surface.
Locate visible evidence, identify technical claims by source and preserve every inaccessible or uncertain surface.
Locate every junction
Photograph the whole reconstructed form before making details of seams. Trace each visible junction to the object edge and note where it disappears behind a support. A line can be a join, crack, carved boundary or reflection. Use technical documentation for classification and keep uncertain lines unresolved.
Separate fit from attachment
Two pieces can align visually without being physically joined, while an internal attachment may have no visible seam. Describe what the image shows: adjacent fragments, continuous contour or visible fill. Do not infer adhesive, dowel or structural method from a visitor view.
Record fills as their own layer
Modern fills may stabilize, bridge or clarify the reconstructed outline. Keep color and extent visible in at least one source frame. If a publication mask removes them, label the derivative clearly. Invisible retouching turns a present reconstruction into an apparently intact ancient surface.
Test the seam from another angle
An oblique view can show whether a line continues across planes and whether fragments sit at different depths. Maintain a safe public position and include camera angle in the caption. Perspective can make a good join appear open or close an actual gap, so compare rather than normalize.
Use inventory history
Confirm that all components share the cited object record and note former numbers where supplied. Museum reconstructions can change as fragments are identified or removed. Date every installation image and do not merge photographs of different states into a timeless composite.
Avoid visual completion
The eye naturally bridges gaps and continues outlines. Make a boundary frame that preserves missing space, mount and backing. Any drawn completion belongs in a separate, cited overlay with a version number. Never blend the proposal into the documentary image.
Compare joins responsibly
When comparing two reconstructions, match scale using published measurements rather than pixels. Label viewpoint, lighting and installation date. Apparent tightness of a seam may reflect image resolution or fill treatment, not the quality or certainty of the reconstruction.
Publish a join log
List observed seams, source-supported joins, fills, supports, edits and hidden areas. Attach creator, capture date, inventory number and source links. A portable log allows later readers to revise the map when conservation records or a new installation become available.
Check continuity by region
Follow contour, texture and decoration across the proposed junction one feature at a time. Photograph each feature at useful scale and keep differences visible. Continuity may support the documented reconstruction, but a visitor image cannot test internal fit, material compatibility or attachment strength.
Separate installation from conservation
A plinth may hold joined fragments while a hidden armature stabilizes the entire object. Record present support without assuming it is part of the conservation join. Use institutional documentation to distinguish exhibition hardware, structural intervention and visual completion.
Build a reversible overlay
Use different line styles for visible seam, source-confirmed join, fill boundary and hidden continuation. Add a legend, date and author. The overlay should be removable without changing the source photograph, allowing another reader to question every category.
Audit detached derivatives
Move one close image outside the project folder and check whether filename, caption and manifest still reconnect it to the whole object and exact join. If not, improve the naming system. Portable context prevents a seam detail from circulating as an unidentified example.
