Prompt de la visualisation photoréaliste.

Use case: photorealistic-natural
Asset type: wide editorial website image for the “Système graphique” section of the Kalpana project
Input images: Image 1 is the official Kalpana crest reference and must be reproduced faithfully on the sign; Image 2 is geographic context only, showing the sandy coastal corridor near Pedra do Sal and Praia da Cutia—do not reproduce it as a map.
Primary request: Create a highly photorealistic architectural visualization of a premium but restrained roadside wayfinding sign guiding guests toward Kalpana.
Scene/backdrop: a narrow single-lane compacted reddish laterite and sand access road in the coastal landscape of Parnaíba, Piauí, Brazil; low fixed dunes, native restinga vegetation, grasses bent slightly by ocean wind, no buildings visible, the sea only subtly suggested in the far distance. The road curves gently into the landscape.
Subject: one elegant low horizontal roadside sign on two very slim dark galvanized-steel posts, realistically installed beside the road without a monumental base. Sign face is deep matte forest green with a thin muted sand-gold perimeter line. Use the official Kalpana crest from Image 1 in a restrained sand-gold monochrome treatment on the left. Large exact text in clean widely spaced uppercase: “KALPANA”. Smaller exact text below: “OCA DO VENTO · KERENA”. A single simple upward direction arrow on the right. The sign must look practical, durable, salt-air resistant, and retroreflective without looking glossy.
Style/medium: premium hospitality architectural photography, extremely realistic materials and vegetation, sophisticated Brazilian coastal eco-resort art direction, understated rather than ostentatious.
Composition/framing: 16:9 wide landscape, driver’s eye-level view from the road, 35 mm lens, sign occupying the right third to center-right and fully readable, curving road creating depth on the left, generous natural landscape around it. No text overlays outside the physical sign.
Lighting/mood: warm late-afternoon natural light after a clear day, soft long shadows, gentle coastal haze, calm welcoming mood, realistic dynamic range.
Color palette: deep forest green, muted sand gold, warm laterite, dune beige, dry and fresh restinga greens.
Text (verbatim): “KALPANA” and “OCA DO VENTO · KERENA”
Constraints: reproduce the official crest faithfully; exact spelling; only one sign; two slim posts; understated premium design; plausible roadside scale; crisp readable typography; no visual clutter.
Avoid: fantasy resort entrance, giant monument, stone plinth, timber sign, ornate tropical clichés, palm-tree avenue, people, cars, buildings, extra logos, extra words, misspelled text, billboards, neon, LEDs, dramatic artificial lighting, map graphics, watermark.
