1. White-background packshot
Cleared the desk clutter and kept the SERUM label, pump and bottle color as they were. The bottle fills less of the frame than marketplace main images usually need, so crop before uploading.
Keep the product exactly as it is, including its shape, label, colors and proportions. Replace the background with pure white (#FFFFFF) and center the product. Light it with soft, even studio light from both sides and add a subtle natural contact shadow under its base. Crisp edges, no color spill, clean e-commerce packshot.

Prompt from Explore: Pure White Marketplace Packshot
2. Lifestyle scene
Bottle, label and pump unchanged. The bottle picks up the warm side light of the new scene, so it does not look pasted in.
Keep the product exactly as it is, including its shape, label and colors. Place it on a raw-cut beige travertine block with a few dried botanical stems beside it. Soft morning window light casts dappled leaf shadows across the scene. Warm, organic mood, shallow depth of field, editorial lifestyle photo.

Prompt from Explore: Travertine Block in Morning Light
3. Sale poster with text
Both headlines came out spelled correctly on the first run. With the aspect ratio left on auto, the model chose a 3:4 portrait layout for the poster on its own.
Turn this product photo into a sale poster. Keep the product unchanged and centered. Add the headline "SUMMER SALE" at the top and "50% OFF" below the product in a bold, clean sans-serif, on a bright coral background with simple geometric shapes. Spell the text exactly as given.

What a real edit costs
The per-image price covers only the generated image. Each of our three 2K edits came to about $0.057 to $0.063 against the $0.0504 list price. The gap is the input photo (about $0.002) plus several hundred thinking and other output tokens per request, billed at $7.50 per million, since 2.1 thinks at medium by default. That is still well under Nano Banana 2's $0.101 list price for a 2K image.
