How This Prompt Works

Copy this Nano Banana Pro text-to-image prompt to create product visuals with photorealistic detail and cinematic lighting. Best in 1:1 framing. Ready for...

Keep the base prompt intact for the first run, then iterate on one variable at a time so the composition stays stable. Keep the generator on 1:1 for the closest match. The mood is anchored by { "image_generation_request": { "subject_settings": { "product_placeholder": "[insert product name here]",...

What to Change First

  • Change the subject block first: { "image_generation_request": { "subject_settings": { "product_placeholder": "[INSERT PRODUCT NAME HERE]",...
  • Adjust the mood through light and backdrop cues: { "image_generation_request": { "subject_settings": { "product_placeholder": "[INSERT PRODUCT NAME HERE]",...
  • Keep the finish constraints aligned while you test variants: { "image_generation_request": { "subject_settings": { "product_placeholder": "[INSERT PRODUCT NAME HERE]",...

Before You Generate

Note 1

Use 1:1 on the first run, then test alternate crops after the base composition is working.

Note 2

Lock the environment before fine styling changes: { "image_generation_request": { "subject_settings": { "product_placeholder": "[INSERT PRODUCT NAME HERE]",...

Best For

  • Product launches, packshots, and controlled commercial mockups.
  • Text-to-image ideation when you want a reliable starting frame in 1:1.
  • Clean studio results where spacing, surfaces, and product separation need to read immediately.

Skip This Prompt If

  • You need loose documentary energy or multi-subject storytelling instead of a controlled product setup.
  • You need to begin with a radically different crop than 1:1 instead of honoring the existing composition hints.
  • You want a loose multi-subject scene instead of a prompt built around one controlled focal point.

Mistakes to Avoid

  • Ignoring the recommended 1:1 crop on the first run. The prompt's composition cues were written for that frame.
  • Changing subject, lighting, and finish together. You lose the stable base that makes the prompt reusable.
  • Dropping the lighting or backdrop cues too early. Those clauses usually carry most of the mood and depth.

3 Ways to Adapt This Prompt

Use these as safe starting edits so you keep the prompt's structure while still making it your own.

Swap the subject, keep the frame

Replace { "image_generation_request": { "subject_settings": { "product_placeholder": "[insert... with your own subject while leaving the camera and composition cues intact.

Retune the mood, not the structure

Keep the subject block, then rewrite { "image_generation_request": { "subject_settings": { "product_placeholder": "[insert... to move the image into a new lighting setup.

Change the finish without breaking geometry

Test a new texture or rendering finish by rewriting { "image_generation_request": { "subject_settings": { "product_placeholder": "[insert... while leaving the scene structure alone.
