A Nano Banana prompt works when it names three things: the subject, the change, and what must stay the same. Keep it short. If two instructions fight, the model drops one. This page is the prompting guide: five rules, a copy-paste format, then examples for photo editing, backgrounds, and product shots.<\/p>\n\n\n\n
Five rules that decide whether a run holds together:<\/p>\n\n\n\n
Run a prompt in three steps. Upload up to nine images in one pass and choose the generation model before you type, because the Base engine wants a short prompt while Pro digests layered ones. Paste one instruction, generate, then change a single variable per rerun instead of rewriting the whole line.<\/p>\n\n\n\n
That discipline is the entire trick. A prompt that names one change and guards what stays gives you a repeatable result. A prompt that asks for four changes at once gives you whichever one the model picked at random.<\/p>\n\n\n\n
The best prompts follow one structure. It helps the model separate the subject from the style from the visual intent.<\/p>\n\n\n\n

These examples show how simple prompts drive the Base model and how structured ones unlock Pro. The table below is the quick-reference version; the longer sets after it show the range.\n<\/p>\n\n\n\r\n
