Prompting guide for Nano Banana Pro

Start with a concise brief that states subject, action, setting, lighting, and camera intent. Specify aspect_ratio early to anchor composition, then choose resolution 1K, 2K, or 4K and an output_format aligned to your workflow. Use num_images to explore controlled variations, keep the best, and refine with short edits. Emphasize what should dominate or be minimized to guide emphasis. Nano Banana Pro responds best to direct language and clear spatial cues.

Examples in Nano Banana Pro:

Cinematic portrait of a violinist on a dim stage, soft rim light, shallow depth of field, 3:4, photorealistic.
Modern kitchen interior, clean daylight, marble island, add a bowl of lemons on the right, 16:9.
Futuristic city street at dusk, rain-slick pavement, neon reflections, pedestrians in silhouette, 21:9.
Editorial product shot of matte black headphones on white seamless, top light, crisp shadows, 1:1.

Pro tips:

Lead with subject and action; prefer a few strong descriptors over long adjective chains in Nano Banana Pro.
Use spatial and scope constraints such as background only, left of the subject, upper-right quadrant.
For typography, specify exact text, placement, and perspective; mention material or mounting when relevant.
Control realism vs style with cues like photorealistic, editorial, illustration; avoid mixing conflicting eras.
Iterate with num_images for 4 to 8 options, refine briefly, and set aspect_ratio before resolution. Nano Banana Pro rewards precise, compact prompts.
