Cinematic perfume bottle with prism rainbow flare

Why this works

This prompt succeeds because it layers three distinct systems that generators handle well independently, and even better together.

Transparent subject + backlight — Perfume bottles are glass, and specifying a backlight through the liquid tells the generator to render translucency and internal glow. This is a well-understood photography technique that appears frequently in training data, so generators reproduce it reliably.

Prism as a physical prop — Rather than asking for “rainbow effects” abstractly, describing a prism “positioned just out of frame” grounds the optical effect in physical reality. Generators interpret prop-based language more consistently than abstract effect requests because they map to real photographic setups.

Layered depth cues — The polished obsidian surface creates reflections below, the backlight creates glow through the bottle, and the shallow depth of field separates foreground flare from the sharp subject. Each layer adds a distinct depth signal, preventing the flat look that plagues many product shots.

Material specificity — Terms like “polished obsidian slab,” “amber-tinted liquid,” and “gold accents” give the generator concrete material rendering targets rather than vague descriptions.

What to change if it fails

• Rainbow flare too overwhelming? Change “casting a rainbow spectrum across the foreground” to “casting a faint prismatic accent along one edge of the bottle.”
• Bottle looks opaque instead of translucent? Strengthen the backlight language: “intense backlight making the liquid glow from within, light transmitting through the glass.”
• Background too busy? Simplify to “solid black background” and remove the gradient reference.
• Gold accents not rendering? Be more specific: “gold metallic cap and gold foil lettering on the label.”
• Too dark overall? Add “well-exposed product” and change “deep charcoal” to “medium gray gradient background.”
