How to use this prompt

1Open Nanobanana in the image tool you already use.
2Upload the reference photo first. This prompt opens with “Use the uploaded image as the primary subject reference.”, so the subject is expected to come from that image.
3Paste the prompt exactly as written. Do not summarise it: the ordering of the clauses is what keeps the composition stable.
4Generate once, then change a single phrase per attempt. Start with the subject clause rather than rewriting the whole prompt.

What to change first

The lens and framing cue is shallow depth of field. Changing it alters depth of field and how much of the scene stays in focus.
The colour direction is warm. Replace only that word to move the grade without touching the composition.
Keep the preservation clauses intact, starting with “Keep textures realistic and well-detailed.”. Those are what stop the edit from changing the subject.
The opening clause — “Use the uploaded image as the primary subject reference.” — fixes the subject; the rest is styling. Swap the subject and the style stays; swap the style words and the subject stays.
