A product still-life prompt that writes texture, light and lens on separate lines

Commercial product still life: a square frosted-glass perfume bottle with a gold metal cap, no text or logo anywhere on the bottle.
Material: fine frosted grain on the glass; the liquid inside is pale amber with slight visible refraction.
Set: resting on a wet black slate slab with a few scattered water droplets; plain dark grey background, nothing else in frame.
Lighting: a single softbox from behind and to the left as a rim light tracing the bottle's edges, with a white bounce card filling in gently from the right.
Lens: 100mm macro, f/4, shallow depth of field, focus on the line where the cap meets the shoulder.
Composition: product in the right third of the frame, slightly below center, generous negative space on the left.
Style: photorealistic, restrained premium advertising look, low saturation, 16:9 landscape.

The usual problem with product-shot prompts is one sentence stuffed with adjectives: “premium, textured, cinematic lighting, stunning.” The model receives a pile of moods, and every generation comes out different.

This prompt gives each line one job: subject, material, set, lighting, lens, composition and style. That pays off twice:

• Easy to adapt. For a watch or a skincare jar you change the first two lines. For a darker mood you touch only the lighting line, so the rest holds still and your results stay comparable.
• Easy to debug. When a render goes wrong, you can tell whether it’s the reflections or the framing and edit the matching line.

Details worth keeping

• “No text or logo anywhere on the bottle”: image models like to invent garbled lettering on packaging, and ruling it out up front saves retries.
• Saying where the light comes from and what it hits is far more reliable than “cinematic lighting.”
• Naming the focus point keeps the shallow depth of field from blurring the product itself.
• The aspect ratio sits on the last line. Midjourney users can drop it and use the --ar 16:9 parameter instead.
