Product prompt guide

How this product shot is built

A translucent glass cake slice containing suspended fruit slices rests on a porcelain dish against folded fabric. GPT Image 2.5 Sunburst renders the contrast between transparent crystal surfaces and organic inner textures cleanly without turning the object into cloudy plastic. The defined geometric silhouette paired with gentle fabric draping provides a clean, premium studio aesthetic suitable for conceptual food and luxury product displays.

  1. framing and subject geometrySquare 1:1 frame. A sharp triangular slice of cake

    Specifies the central geometric wedge shape and confirms the square boundary. Removing this can lead to irregular, melting pastry forms instead of a sharp, recognizable slice silhouette.

  2. material and internal elementsmade of crystal clear glass, with real strawberry slices and kiwi layers suspended inside,

    Establishes the transparent medium while specifying fresh fruit inclusions trapped within. If changed to opaque cake, the light-bending optical effect and surreal visual trick disappear completely.

  3. staging and surface textureon a small porcelain plate over pale pink silk,

    Grounds the slice on an opaque ceramic dish and introduces a complementary fabric texture underneath. Cutting this leaves the glass slice floating awkwardly in blank studio void space.

  4. lighting and editorial genresoft light making rainbow refractions, luxury surreal still life, no text.

    Instructs the model to simulate optical prisms through the glass while blocking unwanted brand watermarks or labels. Without this, glass highlights look dull and flat white.

What to change for your own product

Adapt this luxury still-life formula for cosmetics, jewelry, or signature beverages by swapping the glass object and internal suspension.

Product
Currently a sharp triangular cake slice. Swap for a perfume bottle, skincare jar, or sculpted acrylic sneaker sole.
Suspension Material
Currently real strawberry and kiwi slices trapped in clear glass. Swap for botanical herbs, gold leaf flakes, or frozen air bubbles.
Base and Surface
Currently a small porcelain plate atop pale pink silk. Swap for a matte travertine plinth, polished obsidian slab, or brushed aluminum coaster.
Lighting
Currently soft light casting rainbow refractions. Swap for directional rim light with crisp caustic shadows or warm golden-hour glow.

Model and settings

Run in text-to-image mode with the ratio set to 1:1 to maintain balanced symmetry around the central plate. Keep quality set to high so GPT Image 2.5 Sunburst calculates fine caustic highlights and crisp glass transparency without compression fuzz. If you intend to use the asset for mobile banners or horizontal web headers, adjust the aspect ratio before generating rather than cropping inward later.

When the product shot goes wrong

Glass looks like cloudy plastic or frosted acrylic instead of clear crystal
Change made of crystal clear glass to made of ultra-transparent optical glass with crisp internal caustics and sharp edges.
Fruit slices fuse into the glass exterior or look painted on the surface
Add the words fully submerged deep inside the solid glass interior right after kiwi layers suspended inside.
Pink silk backdrop overpowers the glass slice and creates messy reflections
Replace over pale pink silk with over taut pale pink silk with minimal folds to reduce distracting background wrinkles reflecting across the glass.

Questions about this product prompt

Why did the cake slice turn into real spongy cake instead of glass?

Models sometimes prioritize the word cake over glass. Ensure made of crystal clear glass directly modifies the slice, and consider describing it as a solid glass sculpture in the shape of a cake wedge to eliminate pastry textures.

How do I prevent unwanted text or logo watermarks from appearing on the plate?

The prompt includes no text at the end, which signals GPT Image 2.5 Sunburst to omit plate markings. If tiny simulated logos still appear on the rim, add plain unbranded white porcelain plate to reinforce clean surfaces.

Can I change the suspended fruit to other objects without losing transparency?

Yes, as long as you keep the words crystal clear glass and suspended inside. Replace the strawberry and kiwi slices with botanicals, gold leaf, or whole berries, ensuring the items contrast clearly against the clear medium.
