The exact text-to-image prompt behind this picture, made with GPT Image 2.5 Sunburst.

Prompt

Vertical 2:3 poster frame. A flat vector editorial travel poster of a coral reef seen from above, layered turquoise and teal shallows, a small wooden boat with a striped sail, sea turtles and schools of fish in clean geometric shapes, coral in pink and tangerine, a small title at the bottom that reads "SALT & SUN", no other text.

Make your own version

  1. The words in quotes, "SALT & SUN", are printed in the picture. Keep them short and change them to your own.
  2. Vertical 2:3 poster frame sets the whole feel of the shot. Swap it for another camera style to change the vibe.

Where this idea comes from

Inspired by an idea from @jzaib4269, collected in freestylefly/awesome-gpt-image-2 under MIT. PopNow wrote this prompt and made the example above.

Scene prompt guide

How the scene is composed

An illustrated top-down travel poster of a tropical reef combines flat graphic styling with crisp, legible typography using GPT Image 2.5 Sunburst. The distinct color pairing of turquoise water and warm coral creates depth without needing photographic shading. GPT Image 2.5 Sunburst handles both the clean geometric shapes and the exact rendered text without introducing messy artifacts.

  1. Format and style definitionVertical 2:3 poster frame. A flat vector editorial travel poster

    Sets the flat graphic illustration aesthetic and keeps the layout structured like a vintage print. Removing it causes the generator to produce a photographic underwater shot instead.

  2. Perspective and water paletteof a coral reef seen from above, layered turquoise and teal shallows,

    Locks the birds-eye overhead viewpoint and establishes the cool color foundation. Changing these words alters the depth gradient and shifts the camera to an eye-level angle.

  3. Focal subjects and shapesa small wooden boat with a striped sail, sea turtles and schools of fish in clean geometric shapes,

    Adds contrasting human and marine subjects while reinforcing simplified, non-photorealistic geometry. Omitting this leaves the ocean empty and reduces visual storytelling.

  4. Accent color and typographycoral in pink and tangerine, a small title at the bottom that reads "SALT & SUN", no other text.

    Injects warm contrast against the blue water and directs the model to render exact clean lettering while suppressing random gibberish labels.

Camera and light

The scene relies on a stylized top-down perspective and bold ambient daylight rather than realistic optical camera effects.

Camera
Top-down bird's-eye view looking directly down into the water. Switch to a low-angle waterline view if you want to see both sky and underwater life simultaneously.
Light
Even, flat ambient illumination characteristic of screenprints, with no harsh sun glares or complex shadows. Mention golden hour or deep sunset to shift the water tones into violet and amber.
Scale
The boat serves as a miniature focal anchor against wide expanses of water and coral beds. If the boat appears oversized, reinforce terms like vast shallows or tiny sailboat.

Variations on the scene

Sunset reef poster

Swaps the midday palette for evening tones and replaces turtles with manta rays for a dusk scene.

Prompt

Vertical 2:3 poster frame. A flat vector editorial travel poster of a coral reef seen from above at dusk, layered indigo and violet deep waters, a small wooden boat with glowing lanterns, manta rays gliding in clean geometric shapes, coral in magenta and gold, a small title at the bottom that reads "NIGHT TIDE", no other text.

Split-level waterline poster

Shifts perspective from top-down to a half-above, half-below waterline split view.

Prompt

Vertical 2:3 poster frame. A flat vector editorial travel poster of a tropical reef viewed from water level, half-submerged split view with calm turquoise sea below and sunny sky above, a lone sea kayaker paddling, sea turtles near branching pink coral, a small title at the bottom that reads "ISLAND REEF", no other text.

Deep lagoon diver poster

Replaces the wooden boat with a central freediver and focuses on a deep lagoon formation.

Prompt

Vertical 2:3 poster frame. A flat vector editorial travel poster of a circular coral atoll seen from above, layered azure and deep navy blue water, a solo freediver floating in the center, orbiting schools of silver fish in clean geometric shapes, coral in coral-red and yellow, a small title at the bottom that reads "BLUE ATOLL", no other text.

Model and settings

Keep the 2:3 aspect ratio locked to preserve standard vertical travel poster proportions and leave enough negative space for the bottom title. Setting quality to high ensures that vector edges remain crisp and the font characters generate without jagged artifacts. If you want to use the graphic as a horizontal desktop background or banner, switch the ratio to 16:9 or 3:2 while retaining the high quality setting.

  • Nano Banana 2.1Choose this model if you need 4K resolution output with exceptionally sharp vector contours and crisp title text.
  • Nano Banana ProSelect Nano Banana Pro if you want to expand the poster with complex layout planning, such as adding travel badges, subtitles, or coordinate markers.

When the scene falls apart

The model generates random gibberish words, mock map labels, or fake brand logos across the water.
Keep the explicit phrase "no other text" at the end of the prompt and avoid adding words like vintage advertisement which often trigger unwanted slogan blocks.
Sea turtles and fish appear much larger than the boat, making the scene look surreal rather than stylized.
Add miniature sailboat and specify small distant sea turtles to enforce proper relative sizing across the scene.
The coral formations become overly intricate and crowded, losing the clean vector graphic style.
Replace detailed coral descriptions with minimalist shapes and emphasize wide negative space in the turquoise water.

Questions about this scene prompt

How do I change the poster title text without breaking the font style?

Replace the words inside the quotes, keeping the phrase formatted as a small title at the bottom that reads "YOUR TEXT". Keep phrases short, ideally under four words, so GPT Image 2.5 Sunburst renders clean, well-spaced typography.

Can I change the color palette of the ocean and coral?

Yes, you can swap "turquoise and teal" with other color pairs like "emerald and navy" or change the coral to "lavender and ochre". Sunburst follows exact color directives closely when vector terms are present in the prompt.

Why does the result look like a photo instead of an illustrated poster?

This happens if photographic camera descriptors like aperture or realistic water refraction are introduced. Ensure keywords like "flat vector editorial travel poster" and "clean geometric shapes" remain intact at the beginning of your prompt.
