1. Event Poster: SCIENCE AFTER HOURS

Nano Banana Pro museum night poster with the headline SCIENCE AFTER HOURS and the date FRI 23 OCT centered at the top, above a ringed blue planet, a brutalist observatory and a visitor in a red jacket

Settings: 1:1 · 1K · PNG · 1024×1024

Design a square museum poster for a fictional evening event. Set the exact headline SCIENCE AFTER HOURS and the exact date FRI 23 OCT, with no other words. One luminous ringed blue exoplanet hovers above a brutalist observatory at twilight; one small visitor in a red jacket stands in the foreground. Clear Swiss-grid information hierarchy, crisp modern typography, deep ultramarine and warm red, striking editorial illustration, no logos, no watermark.

The headline and the date each appear once, spelled correctly, centered above the planet. For your own event, swap the words after exact headline and exact date, then replace the planet and the observatory. Keep with no other words: it stops stray text from creeping in.

2. Storefront Sign: MORNING BREW CO.

Nano Banana Pro gold-leaf coffee shop window sign reading MORNING BREW CO. in serif capitals with est. 2024 in script, warm café interior and street reflections behind the glass

Output size: 1536×2752; suggested settings: 9:16 · 2K

A hand-painted gold-leaf sign in a modern specialty coffee shop window, elegant serif lettering reading 'MORNING BREW CO.' with a small script subtitle 'est. 2024' beneath it, warm natural daylight streaming through the glass, soft bokeh reflections of a city street, photorealistic commercial photography, crisp perfectly legible typography with correct spelling, shallow depth of field, editorial lighting

Put each line of copy in single quotes, then name the type style (elegant serif, small script) and the position (beneath it). Both lines came out right on the first pass. For a brand concept, change the name, the year and the material (gold leaf, neon, carved wood) and keep crisp perfectly legible typography with correct spelling.

3. E-commerce Hero Shot: Trail-Running Sneaker

Nano Banana Pro trail-running sneaker product shot, toe pointing left, with a coral mesh upper, charcoal overlays and a translucent lime lugged outsole on an off-white seamless backdrop

Settings: 1:1 · 1K · 1024×1024

Create a square premium e-commerce product photograph of one original trail-running sneaker, three-quarter side view with the toe pointing left. The shoe has a vivid coral mesh upper, charcoal overlays, two visible laces crossing the tongue, and a translucent lime outsole with a distinct lug pattern. Set it on an off-white seamless backdrop with a soft grounded shadow and directional studio light. One shoe only, no feet, no text, no logo, no props.

Generate with this prompt →

Toe direction, palette, lug pattern, backdrop and grounded shadow all match the brief; naming a direction like toe pointing left is what keeps a catalog grid facing the same way. For your product, change the shoe type, the three colors and the outsole line, and keep One shoe only, no feet, no text.

4. Catalog Product Shot: Over-Ear Headphones

Nano Banana Pro over-ear headphones with matte forest-green earcups, an amber stitched headband and three copper buttons on the left earcup, on a pale-gray backdrop

Settings: 1:1 · 1K · PNG · 1024×1024

Create a square premium catalog photograph of one original pair of foldable over-ear wireless headphones, matte forest-green earcups, an amber stitched headband, and exactly three small copper control buttons in a straight row on the visible left earcup. Both earcups face the viewer. Put it on a seamless pale-gray backdrop with soft studio lighting and a grounded shadow. No phone, no person, no text, no logo, no extra objects.

Generate with this prompt →

Writing count, arrangement and position together (exactly three small copper control buttons in a straight row) gives you three clearly lined-up buttons. Both earcups face the camera, which is the front-on view a catalog needs.
