0–7 minutes: copy the record
Write institution, inventory number, material, date, provenance and dimensions.
7–15 minutes: observe from approach
Record silhouette, dominant colour, light direction, glare and relation to neighbours before photographing.
15–25 minutes: move laterally
Within permitted circulation, compare surface, shadow and reflection from two positions.
25–33 minutes: inspect protected areas
Look for recesses, joins, backs and edges that respond differently. Describe without diagnosing.
33–41 minutes: read the display
Note case glass, mount, low-light policy, facsimile or screen and what each enables.
41–46 minutes: open the official image later
Use the inventory number to compare controlled photography or technical media.
46–50 minutes: write four sentences
Separate direct appearance, lighting condition, institutional claim and remaining uncertainty.
Choose the object without blocking others
Select an object visible from more than one permitted standing position and with a readable inventory number. Avoid narrow circulation points or popular cases where sustained observation would obstruct visitors. If the gallery is busy, divide the method into shorter returns. The quality of a record never justifies ignoring staff directions, barriers or other people’s access.
Use a fixed vocabulary
Before beginning, choose plain terms for light direction, reflection, shadow, visible colour and surface. Consistent wording makes the three conditions easier to compare. Avoid technical material or conservation diagnoses unless the institution supplies them. A repeatable vocabulary is not a substitute for measurement; it is a way to keep ordinary observation organised and appropriately modest.
Mark every source immediately
Write O beside direct observation, L beside label text and I beside an official image or institutional record. Include the image caption and access date. These tiny markers stop a polished final paragraph from blending three kinds of evidence. They also make later correction easier if the collection record changes or a remembered detail turns out to come from photography.
Allow a no-result outcome
Some objects will not reveal a meaningful change as you move, and an official technical image may not exist. Record that honestly. A method is valuable because it controls the question, not because it guarantees discovery. The absence of visible variation can direct attention to diffuse lighting, opaque material or limited access without turning any of those possibilities into a diagnosis.
Finish with one bounded claim
Draft a sentence that names the object, observed condition and visible effect, followed by a sentence naming the official evidence and remaining limit. Remove adjectives that imply certainty beyond the record. This final discipline turns fifty minutes of looking into a useful, citable note while preserving the difference between a visitor’s encounter and a museum’s technical interpretation.
Keep the visit dated
Record institution, object number and observation date. Display and access can change, while the date tells later readers which conditions you actually encountered.
Use current institutional guidance for access, photography and conservation.
