  "title": "Glazed pottery: check the highlight and motif during a small camera shift",
  "description": "A ceramic-shot practice that separates a highlight changing with viewpoint from a pattern sliding across the glaze. Use a small camera shift and compare the rim, motif and base.",
  "goal": "Plan a restrained viewpoint change around one glazed vessel while its painted motif stays attached to the surface. This original illustration and method are untested teaching materials, not a validated rendering of real ceramic reflectance.",
  "preparation": [
    "Use the supplied original vase illustration for practice, or your own permitted photo with the rim, painted motif and base clearly visible.",
    "Choose one modest movement: a slight sideways camera shift. Keep the vessel and light source still so you can isolate viewpoint-related reflection changes.",
    "Before generating, identify the rim ellipse, a visible motif junction and the foot-to-surface contact point. These are different checks from the highlight itself.",
    "Use the separate detail drawing to see how the painted strokes meet. It is a reference for inspection, not proof that the model can retain exact decoration or reconstruct unseen sides."
  ],
  "prompt": "Start from the uploaded image. The glazed ceramic vessel stays fixed on the surface under one steady soft side light. The camera makes one very small sideways shift while keeping the full vessel in view. Preserve the vessel silhouette, rim, base and the placement of the painted motif on the surface. Allow the soft glaze highlight to change subtly with the viewpoint; do not turn the painted motif into a moving reflection. End with the camera settled. No vessel rotation, no new ornament, no added writing.",
  "steps": [
    {
      "title": "Identify paint separately from reflection",
      "body": "On the first frame, distinguish the painted strokes from the pale glaze highlight. Mark one stroke junction and the rim shape for comparison. A highlight may shift with the view; the painted motif should stay attached to the same part of the vessel."
    },
    {
      "title": "Keep the viewpoint change small",
      "body": "Request a slight sideways shift with the whole vessel visible, steady lighting and no object rotation. A large orbit reveals surfaces the source does not show and makes this simple highlight-versus-paint exercise a different task."
    },
    {
      "title": "Compare geometry, then surface detail",
      "body": "Check the rim and base first, then the motif junction and finally the highlight. Inspect beginning, middle and ending. Do not accept a moving motif because the glaze looks glossy; material appearance and decoration stability have separate acceptance checks."
    },
    {
      "title": "Revise the relevant motion",
      "body": "If the vessel shape changes, simplify to a stationary camera before retrying the small shift. If only the motif slides, reduce the viewpoint change and use a clearer source. For exact craft decoration in a commercial shot, confirm it through permitted real footage or a controlled editing workflow."
    }
  ],
  "acceptance": [
    "The rim remains one coherent opening and does not change into a second lip.",
    "The foot remains attached to the same surface without floating.",
    "The visible painted-stroke junction keeps its identity and surface position.",
    "No additional painted band or ornament appears on the visible side.",
    "The glaze highlight changes gently without behaving like painted artwork.",
    "The small camera shift stops cleanly; the vessel itself does not begin to rotate.",
    "Unseen surface decoration is not treated as verified product detail."
  ],
  "troubleshooting": [
    {
      "symptom": "The motif slides like a light reflection",
      "change": "Explicitly distinguish painted decoration from the glaze highlight and reduce the sideways shift. Compare one visible stroke junction rather than evaluating the whole pattern from memory."
    },
    {
      "symptom": "The rim becomes oval in an inconsistent way",
      "change": "Check whether the camera request is larger than intended. First retry with a stationary camera to separate input ambiguity from viewpoint change, then reintroduce a smaller shift."
    },
    {
      "symptom": "A new ornament appears around the back",
      "change": "Keep the movement small enough to stay within the source view. If the actual rear surface must be shown, provide additional permitted material through a supported workflow or film it directly."
    },
    {
      "symptom": "The glaze looks like animated liquid",
      "change": "Remove flowing glaze or shimmering surface language. Ask for a steady material with only a soft highlight responding subtly to the viewpoint."
    }
  ],
  "ending": "End with the vessel fixed and the camera settled. Keep a three-point comparison of the rim, motif junction and foot with the accepted take; the highlight is checked separately from these stable features.",
  "assetCaption": "Original editable glazed-vase vector illustration with a separately drawn motif-detail reference. These are practice and inspection materials, not photographs or generated output."
