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

Prompt

Vertical 4:5 portrait frame. A Pacific Islander marine researcher in a cobalt waterproof jacket and charcoal field trousers stands on a rock shelf beside shallow tide pools, holding a closed specimen notebook at her side. Wind lifts her short curls as she looks directly into the lens. Cloud filtered coastal light, eye level 80mm environmental portrait, seafoam water and slate stone with one bold blue accent, natural skin and quiet confidence, no logos, no text.

Portrait prompt guide

Why this portrait prompt works

A Pacific Islander marine researcher stands on a rugged coastal rock shelf under diffused overcast skies. The prompt balances functional field wardrobe styling with authentic environmental context, using an 80mm framing command to soften the coastal background. GPT Image 2.5 Sunburst renders clean facial textures and water reflections without over-saturating the marine landscape.

  1. subject and outfitVertical 4:5 portrait frame. A Pacific Islander marine researcher in a cobalt waterproof jacket and charcoal field trousers

    Defines the vertical framing, subject ethnicity, and functional outdoor field gear, preventing generic studio clothes or fashion poses.

  2. pose and environment settingstands on a rock shelf beside shallow tide pools, holding a closed specimen notebook at her side.

    Establishes her physical location on the rocky coastline and provides a natural prop for her hand to prevent awkward finger positions.

  3. expression and hair motionWind lifts her short curls as she looks directly into the lens.

    Adds subtle motion to her hair and locks direct eye contact with the viewer for an engaging, grounded portrait.

  4. lighting and camera framingCloud filtered coastal light, eye level 80mm environmental portrait, seafoam water and slate stone with one bold blue accent,

    Sets soft overcast illumination, realistic focal length compression, and a controlled palette centered on neutral rocks and the blue jacket.

  5. texture and styling constraintsnatural skin and quiet confidence, no logos, no text.

    Ensures realistic skin pores instead of plastic smoothing, while keeping technical field gear free of fictional brand lettering.

Keeping the same face

To keep the same researcher consistent across multiple field locations or swap in your own identity, maintain these core physical and wardrobe anchors in every iteration.

Ethnicity and hair structure
Keep Pacific Islander and short curls consistent in every generation, or replace both descriptors specifically with your own facial features and hair texture.
Signature cobalt waterproof jacket
Retain the cobalt waterproof jacket across different shots to give the character a recognizable field uniform that AI models track consistently.
Field prop interaction
Lock the closed specimen notebook into her hands or under an arm across scenes to preserve her researcher role and stabilize hand geometry.

Three ways to make it yours

Nordic Geologist on Basalt Shore

Swaps the subject to an older male geologist and changes the color accent from cobalt blue to ochre yellow against dark basalt.

Prompt

Vertical 4:5 portrait frame. A mature Nordic male geologist with a silver beard in an ochre waterproof jacket and charcoal field trousers stands on a dark basalt rock shelf beside tidal surge channels, holding a closed brass compass at his side. Wind lifts his hair as he looks directly into the lens. Cloud filtered coastal light, eye level 80mm environmental portrait, seafoam water and black stone with one bold yellow accent, natural skin and quiet confidence, no logos, no text.

South Asian Ecologist in Mangroves

Transfers the scene to a muddy mangrove habitat with an emerald green jacket focal point.

Prompt

Vertical 4:5 portrait frame. A South Asian female ecologist in an emerald waterproof jacket and khaki field trousers stands on an exposed mudflat beside root-tangled estuary pools, holding a closed water sampling kit at her side. Wind rustles her tied back hair as she looks directly into the lens. Cloud filtered coastal light, eye level 80mm environmental portrait, brackish water and wet silt with one bold green accent, natural skin and quiet confidence, no logos, no text.

East Asian Marine Biologist on Pier

Moves the researcher onto a wooden coastal pier while using an East Asian male subject with a crimson jacket.

Prompt

Vertical 4:5 portrait frame. An East Asian male marine biologist in a crimson weather-resistant shell jacket and dark cargo pants stands on a wet timber jetty beside surging kelp beds, holding a closed waterproof clipboard at his side. Ocean breeze tousles his hair as he looks directly into the lens. Cloud filtered coastal light, eye level 80mm environmental portrait, dark ocean swells and weathered wood with one bold red accent, natural skin and quiet confidence, no logos, no text.

Model and settings

Keep the aspect ratio set to 4:5 for standard vertical portrait framing that balances the researcher and her surrounding coastal environment. Run the generation in text-to-image mode with quality set to high so GPT Image 2.5 Sunburst captures crisp water reflections and realistic fabric weave. If you want a wide shot showing more of the tide pools, switch the aspect ratio to 16:9 while leaving quality on high.

  • FLUX.2 ProSwitch to FLUX.2 Pro if you want strict control over precise jacket hues or need photorealistic coastal textures with pinpoint color matching.

If the portrait comes out wrong

Plastic or overly smoothed skin textures on the face
Ensure the phrase 'natural skin' remains in the prompt and remove any generic beauty modifiers like 'flawless' or 'perfect lighting'.
Mangled or unnatural hand anatomy around the notebook
Specify 'holding a closed specimen notebook at her side' with the object state clearly closed rather than leaving hand actions open-ended.
Harsh, blown-out midday sun ruining the overcast mood
Replace vague lighting terms with 'cloud filtered coastal light' and 'slate stone' to enforce soft diffusion and muted shadows.
Gibberish outdoor brand logos appearing across the waterproof jacket
Keep 'no logos, no text' explicit at the very end of the prompt to prevent the model from hallucinating technical brand emblems on the outerwear.

Questions about this portrait prompt

How do I prevent the cobalt jacket from looking unnaturally saturated?

The prompt pairs 'cobalt waterproof jacket' against 'slate stone' and 'cloud filtered coastal light'. This deliberate contrast keeps the blue vivid without letting GPT Image 2.5 Sunburst oversaturate the overall scene. If it appears too bright, replace 'cobalt' with 'muted slate blue'.

Can I replace the specimen notebook with other field equipment?

Yes, you can swap the notebook for handheld scientific gear such as a refractometer, water test vial, or digital salinity meter. Make sure to describe the object as held resting at her side to prevent awkward finger postures.

Why does the prompt specify an 80mm lens for an outdoor shot?

An 80mm focal length flattens facial features naturally while providing gentle optical compression. It keeps the researcher sharp in the foreground while rendering the tide pools and crashing seafoam as a complementary, slightly blurred environmental backdrop.
