So you want to share a perfect and stunning birthday picture, but you don’t have a recent photo that fits the vibe. Or maybe you want to surprise your wife or friend with a celebratory, beautiful image without organizing a professionally lit photoshoot.

In this tutorial, you can learn how to use Google Gemini Nano Banana Pro to take a single reference image and transform it into an incredible and high-quality festive scene of birthday. It’s very easy to understand and implement the process.

Why Use Gemini for AI Images?

There are many online AI image generators, but the Nano Banana Pro model excels at understanding complicated prompts and maintaining character likeness. You can keep the person’s facial features recognizable while completely modifying the outfit, lighting, and background.

Step-by-Step Guide

• Select your reference image
• Upload to Gemini
• Write the Perfect Prompt

Here is the exact prompt I used to create the image:

Create a medium-shot scene featuring the young woman from the attached image, with long, dark, wavy hair. She is smiling warmly while resting her head gently on her hands. She wears a white dress and is seated at a table in front of a blue birthday cake topped with two lit candles and delicate butterfly decorations.

The background consists of a white wall adorned with purple butterfly-shaped cutouts, white balloons, and a “Happy Birthday Iqra” banner written in elegant purple script. The entire scene is enhanced with warm, soft lighting from decorative string lights, creating a cozy and celebratory atmosphere.

Generate and Refine

Hit enter, and Gemini will work like magic. If you are not satisfied with the first result, don’t worry! You can ask Gemini to “make the lighting warmer” or “change the cake color to pink” to tweak the image until it’s exactly what you envisioned.
