Skill #40 — House design & interior visualisation, used as heritage reconstruction images (2026)
Written 26 Oct 2026 (bizdev cc597974).
What practitioners and platforms say
- Meta labels AI-made images it detects (C2PA/IPTC signals) with "AI info" on Facebook, Instagram and Threads, and requires creators to disclose photorealistic AI video or realistic audio (about.fb.com, 'Labeling AI-Generated Images', Feb 2024; Meta Help 'How AI-generated images are labeled', read 26 Oct 2026). In 2026 AI disclosure is mandatory on Meta ads (coinis.com round-up, 2026; not checked against Meta's ad policy page).
- Heritage visualisation practice (The London Charter for computer-based visualisation of cultural heritage, 2009): say what a picture is based on, keep evidence apart from conjecture, and publish the sources. Archaeology outreach research (Internet Archaeology 46; Richardson, JCAA 2019) finds reconstructions and 'how it looked' images draw the public in, and trust depends on showing the evidence.
How-to
- Two kinds of image, never mixed: (a) a GENERIC period scene ('a typical Vale farmhouse c.1840'), AI-rendered, captioned 'Illustration: not a picture of Tŷ Mawr'; (b) an EVIDENCE diagram of Tŷ Mawr itself, drawn (PIL), every element tied to a record, marked 'Illustration · not to scale', positions we do not know marked 'position indicative'.
- Put the label ON the image (it travels when shared) and again in the caption. For AI renders, add Meta's AI label when posting in-app; never present an AI render as a photograph.
- Sources on the image: record IDs (e.g. Heneb HER 02038s; GGAT 1990 event E003872) and, for HER data, the acknowledgement 'Derived from information held by the Heneb HER Charitable Trust'.
- No likeness of real family members; no people's faces close-up; no insignia; no text inside AI renders (models garble it; add text in PIL).
- Pair each image with ONE question ('Whole farm, or Parcel B?') and one Cedwyn page.
Applied to Cedwyn
- files/promo/illus-farmyard-layout-records-cc597974.png — evidence diagram (house plan, dairy, rear wing, barn, church, quarry road) from HER 02038s + GGAT 1990.
- files/promo/illus-vale-farmhouse-c1840-cc597974.png — generic period reconstruction (render), labelled.
- Post order: diagram first (it carries sources), generic scene second. Measure saves/shares vs the restored-photo posts.
