Optimize for search and engagement **without inventing** anything.\n\n**INPUTS**  \n- `ALT`: {{ $('Limit').item.json.alt }}  \n- `EXIF (JSON or text)`: {{ JSON.stringify(JSON.parse($json.lr_asset).payload) }}\n\n**GOAL**  \nProduce **exactly 3 lines** under **220 total characters** (line breaks included):  \n1) **Action phrase (-ing) + brief outcome**; include **1–2 intent terms** from ALT if present (e.g., “portrait”, “long exposure”). **Max 12 words.**  \n2) **Gear & settings** on one line with an en dash:  \n   `<CameraModel> + <Lens> — <Shutter> · f/<Aperture> · ISO <ISO> · WB <KelvinIfKnown>`  \n   - Use EXIF fields **only if present**: make/cameraModel, lensModel, focalLength and FocalLengthIn35mmFilm, fNumber, exposureTime, iso, whiteBalance (Kelvin or “Auto”).  \n   - If focal length exists but not in lens name, **prefix it** (e.g., `35/1.8`). Display FocalLengthIn35mmFilm too (format: \"(28 mm eq. 35 mm)\")\n   - Format shutter `1/250s`; aperture `f/1.8`.  \n   - Missing field? **Omit** it. **No inference.**\n3) **5–10 hashtags** (lowercase, **deduped**) using layered strategy:  \n   - **Broad:** always `#photography` + **one** brand/lens tag if present (e.g., `#fujifilm #fujifilmxseries\n #fujilove`, `#xe5`).  \n   - **Mid-tail:** 1–3 subject/genre from ALT (e.g., `#portrait`, `#streetphotography`).  \n   - **Niche:** 1–2 specific technique/gear terms from ALT/EXIF.  \n   - **Location:** add 1–2 only if GPS/city exists in EXIF (e.g., `#paris`, `#montmartre`).\n   - **Mentions:** if the EXIF description/caption/title/userComment contains Instagram-style mentions (e.g., `@name`), **append them verbatim at the end of line 3 after the hashtags**. Deduplicate; do not invent; preserve exact handles. If the 220-character limit is exceeded, **remove niche hashtags first**, then mid-tail if needed, but keep mentions.\n\n\n**STYLE & SEO RULES**  \n- English only. Human, concise, non-salesy.  \n- No emojis unless clearly in ALT. No quotes. **No trailing spaces.**  \n- **Zero inference:** do not assert people/brands/places/conditions not in ALT/EXIF.  \n- **Deduplicate intelligently:** avoid repeating the exact same keyword in line 1 and hashtags if it reduces variety; keep the most useful mix for search.  \n- Keep line 2 compact and readable (models/settings aid search without spam).\n\n**OUTPUT (exact format)**  \n<action + outcome with intent terms>\n<gear & settings>\n<hashtags>"
