Lisa Ernst · 12.12.2025 · Technology · 4 min

New Year's Eve and New Year's Day 2026 offer the opportunity to stand out with AI-generated portraits. Gemini 2.5 Flash Image, also known as “Nano Banana,” allows for editing existing photos to adapt them to various scenarios like fireworks, rooftop parties, or cozy cabins without altering the face and expression. This guide explains how to use Gemini 2.5 Flash Image for impressive New Year's portraits.

Introduction & Fundamentals

Gemini 2.5 Flash Image, referred to as “Nano Banana” by Google, is a model for image generation and editing using prompts. (developers.googleblog.com, aistudio.google.com). It enables precise local edits and multi-step iterations (developers.googleblog.com, developers.googleblog.com). Users can utilize it via Google AI Studio (aistudio.google.com) and the Gemini API; for businesses, it is also available through Vertex AI (developers.googleblog.com, docs.cloud.google.com). The generated content is realistic enough to mimic “real memories,” which is why transparency and labeling are important.

Technical Aspects & Labeling

Gemini 2.5 Flash Image is optimized for fast and efficient image generation and editing (docs.cloud.google.com). The workflow involves uploading a photo, applying a prompt, and progressively refining the result (developers.googleblog.com).

All images created or edited with Gemini 2.5 Flash Image include an invisible SynthID watermark (developers.googleblog.com, aistudio.google.com, ai.google.dev). SynthID is robust against typical image modifications like cropping or compression (deepmind.google). Meta plans to label AI content through labels and signals (about.fb.com). This means that realistic-looking New Year's photos should be labeled as manipulated media.

Prompt Strategies & Examples

A good source photo with a clear face and soft lighting is crucial. The photo is uploaded to Google AI Studio (aistudio.google.com) Gemini 2.5 Flash Image (aistudio.google.com) is selected, and a conservative initial prompt is formulated. The strategy is multi-step refinement: first stabilize the identity, then the scene, and finally details (developers.googleblog.com, developers.googleblog.com). A similar approach can also be used in the Zerlo AI image generator (zerlo.net) ..

The prompt formula for consistent results is: Subject → Outfit → Environment → Lighting → Style/Look → Camera/Optics → Identity Assurance. The identity assurance in this case is a clear instruction like “identity/face unchanged” or “same person,” to avoid free interpretation by the model. (developers.googleblog.com).

Frequently Asked Questions (FAQ)

Here you will find answers to frequently asked questions about image editing with Gemini 2.5 Flash Image.

How do I keep the face the same?

The identity rule should be at the beginning of the prompt, e.g., “identity/face unchanged, same person, no beauty retouching, natural skin.” Gemini 2.5 Flash Image offers “character consistency,” which can be utilized through clear prompts. (developers.googleblog.com).

Why does skin look plastic?

This often happens when the prompt implies “glamour” or “perfect” or demands “sharp” too aggressively. Countermeasures include specific instructions like “natural pores,” “no smoothing,” “fine film grain,” or “realistic highlights.” These points should be corrected iteratively without redoing the entire scene. (developers.googleblog.com).

How do I prevent weird hands?

Hands are a common area for errors. In case of errors, targeted repair should be done, e.g., with “anatomically correct fingers,” “no extra fingers,” or “no double rings,” while retaining other elements like outfit and background. The error fix prompt is intended for this.

What is the image size for Reels?

9:16 is recommended for Reels; 1080x1920 pixels is considered the optimal size in creator guides. (buffer.com). Instagram accepts Reels up to this aspect ratio. (help.instagram.com).
