Copy a prompt, open the tool and adapt it to your project.
New setting from your product photo
- Reference: your photo
- 1:1
- 2K
- PNG
From your photo, keep the serum bottle exactly the same: shape, label, colors and reflections. Replace only the background with a light marble bathroom and a blurred green plant, soft morning light, and add a natural shadow under the bottle.
Same person, new outfit
- 2 references: the person and the jacket
- 2:3
- 2K
Image 1: the person. Image 2: the jacket. Show this person wearing exactly this jacket, standing on a sunny street, full-body framing, natural morning light. Keep the face and hairstyle strictly the same, as well as the jacket’s color, fabric and buttons.
Build a scene with your products
- 4 references: the products
- 16:9
- 4K
- JPG
Images 1 to 4: our four scented candles. Arrange them on a light wooden shelf in front of a beige wall, with a few eucalyptus branches and soft late-afternoon light. Keep each candle’s label, colors and shape exactly the same.
Translate a poster without touching the layout
- Reference: the poster
- Auto
- 2K
Translate all the text on this poster into Spanish. Keep exactly the same layout, fonts, colors and images. Do not change anything else.
Website banner for a bookshop
- 4:1
- 4K
- Text only
Panoramic banner for an independent bookshop’s website: wooden shelves full of colorful books, a green velvet armchair, a lamp with a warm glow, late-afternoon light. On the left, the title "New season reads" in cream serif letters; keep the right side clear for a button.
Mascot for a juice brand
- 1:1
- 1K
- Text only
Create the mascot of a fruit juice brand: a smiling orange wearing a green cap and white sneakers, dynamic pose, thumbs up. Colorful 3D illustration style, plain pale yellow background, no text.
Tips for better results
- Describe the scene in sentences rather than a list of keywords: Google recommends this approach for the Nano Banana family.
- For an edit, name exactly what changes, then add “keep everything else the same: style, lighting and composition”, the wording Google suggests.
- With several references, number them in the prompt (“Image 1: the product, image 2: the setting”) to give each one a role.
- For a recurring character or mascot, reuse the same reference image in every creation instead of describing it again.
- Use photography terms for framing (wide angle, close-up, low angle, 85 mm lens), as Google suggests.
- Validate the composition in 1K, then rerun the same prompt in 2K or 4K for the final version.
Good to know
- To edit a result, add it from your Deepnia library as a reference in a new creation, then describe the next change.
- For the most faithful results, pick up to 10 object references and 4 character references per creation: that is where Google documents the highest fidelity.
- Pick 9:16 for stories, Reels and TikTok, 4:5 or 1:1 for feed posts, 16:9 for YouTube and 4:1 or 8:1 for a website banner.
- Before you publish, proofread every piece of text and every translation, and check infographic figures, small faces and fine details.
