Nano Banana
generador de prompts.

Nano Banana, el modelo de imagen Gemini de Google, responde mejor a frases descriptivas —una escena explicada como la presentaría un fotógrafo— que a una lista de palabras clave.

El generador escribe un prompt narrativo a partir de tus opciones, ordenado como se lo explicarías a un fotógrafo: sujeto, lugar, luz y cámara.

Cómo escribir mejores prompts para Nano Banana.

01

Describe, no enumeres

Unas pocas frases bien construidas sobre el sujeto, el lugar y la luz suelen superar a una larga cadena de etiquetas separadas por comas.

02

Di qué debe quedar igual

En las ediciones posteriores, nombra los elementos que se mantienen (pose, vestuario, luz) y luego el único cambio que quieres.

03

Indica la relación de aspecto aparte

Configura la relación de aspecto en los ajustes de la herramienta cuando exista la opción; el generador la muestra como un parámetro aparte.

04

Itera en pasos pequeños

Gemini es bueno con las ediciones sucesivas. Genera una vez, luego cambia una sección cada vez y vuelve a copiar el prompt.
