AI cold drink product photo: condensation and ice from a packshot

For an AI cold drink product photo, send your real bottle or can as the reference, prompt for condensation droplets, ice and a cool backlight, and tell the model to keep the label, cap and shape identical. Condensation hides detail, so check the label text after every pass and compare it with the source.

Prompt the effect, not the product

Describe the scene: cold surface, tiny droplets, a few ice cubes, a dark gradient, a cool rim light and a soft reflection. Keep a separate sentence that lists what must not change: the label artwork, the logo, the color and the proportions.

What condensation breaks

Droplets can bead over the label and make the model smudge or redraw the print. Check the brand name, the volume text and the small legal line. If the label changed, reduce the droplet request near the label, or generate the cold scene and composite the original label back on.

Use drafts then a final

Nano Banana 2 lists 0.5K, 1K, 2K and 4K. Try the idea at the smaller tier, choose the best composition and then regenerate at 2K or 4K. Nano Banana Pro is the heavier option when fine texture matters, and Sume's catalog prices it above Nano Banana 2 on the endpoints call.

Review checklist

• Label text matches the packshot.
• Ice and droplets look physically placed, not pasted.
• Reflection and shadow agree with the light direction.
• Cap, neck and base shapes are unchanged.
• The image is marked as a rendered scene wherever a platform asks.

Keep the edit lineage

Re-run each variation from the original bottle photo, not from the last output, so small errors do not stack. Related product notes are in AI product photo retouching.
