Style prompt guide

Style traits to keep

Sculptural glass fruit glows with internal brilliance, resting on cool stone under sharp studio lighting. GPT Image 2.5 Sunburst renders the translucent amber, purple, and green volumes with authentic optical physics, letting light pool across the marble. The prompt succeeds because it explicitly demands colored caustics and blown-glass material properties, preventing the fruit from appearing like opaque plastic toys.

The blown-glass aesthetic relies on convincing optical distortion, transparent volume, and clean surface contact. Four visual traits define its craft-oriented render style.

Texture
Smooth, fire-polished glass shells display subtle thickness variations, contrasting cleanly against the fine matte grain of the marble base.
Light
Hard directional rays generate tiny white specular glints along the edges and project vibrant, curved caustic halos across the floor.
Palette
Luminous jewel tones—citron yellow, ruby plum, amethyst grape, and golden pear—stand out without clashing thanks to neutral cream and white staging.
Composition
A centered studio grouping gathers the transparent forms into a clustered still life, maintaining balanced negative space along the perimeter.

What defines this look

  1. Medium and composition setupSquare 1:1 frame. A still life of fruit made entirely of colored blown glass,

    Establishes the artistic technique and ensures the fruit objects are formed from hollow, hand-worked glass rather than solid ceramic or real organic produce. Removing this causes the model to generate ordinary edible fruit.

  2. Subject list and stagea pear, a lemon, a bunch of grapes and a plum, on a white marble surface,

    Specifies recognizable fruit shapes that bring varied hues to the arrangement, balanced by a neutral reflective stone ground. Changing marble to wood or fabric dampens the crisp reflections.

  3. Optical lighting directivebright light refracting through them and casting colored caustics,

    Instructs the engine to trace light passing through curved transparent shells to form luminous color pools on the surface. Without the mention of caustics, shadows turn dull, flat, and gray.

  4. Finish and background stylingminimal premium 3D render with photographic realism, cream background, no text.

    Enforces a clean luxury product aesthetic against a soft neutral backdrop while blocking stray typography. Altering this can introduce noisy kitchen clutter or overly cartoonish 3D smoothing.

Blown glass floral bouquet

Uses thin, delicate glass geometries to capture botanical forms with complex light scatter.

Prompt

Square 1:1 frame. A blooming peony and tulip bouquet made entirely of colored blown glass, arranged inside a clear bowl on a white marble surface, bright light refracting through delicate petals and casting colored caustics, minimal premium 3D render with photographic realism, cream background, no text.

Model and settings

Keep the 1:1 square ratio when producing balanced tabletop still lifes, as it neatly frames the grouping without excessive dead space at the margins. If you want to use the result as an editorial banner or desktop display, shift the aspect ratio to wide landscape. Set quality to high to preserve delicate refraction lines and specular edge highlights on the curved glass. In text-to-image mode, provide complete descriptive details instead of relying on input pictures.

When the style drifts

The fruit looks like opaque molded plastic rather than translucent glass.
Add 'hollow, transparent Murano glass with specular reflections' and emphasize 'high transparency' right before the fruit list.
Shadows beneath the fruit appear dark and muddy without colored light.
Replace 'bright light' with 'focused spotlight creating vivid, luminous colored caustics pooled across the surface'.
The scene generates a messy kitchen or dining room scene behind the fruit.
Strengthen the backdrop instruction to 'isolated against an empty, seamless cream studio backdrop with zero props'.

Questions about this style prompt

How do I make the glass look hollow rather than solid?

Specify 'thin-walled blown glass' or 'hollow art glass'. This prompts the model to generate internal wall reflections and highlight shifts that signal empty space inside each piece.

Why are the colored caustics not showing up on the marble?

Caustics require strong contrast to stand out. Emphasize a 'harsh directional key light' and ensure the surface is described as a 'bright white polished marble surface' to maximize caustic visibility.

Can I add air bubbles or gold leaf flecks inside the glass fruit?

Yes. Insert phrases like 'trapped micro-bubbles' or 'subtle gold leaf foil suspended inside the glass walls' directly after the blown glass description.
