Black & White Trend Goes Viral On Instagram: Best AI Prompts To Generate Photos On ChatGPT Or Nano Banana

Black-and-white photography is having a major moment on Instagram, and this time, you don't need a DSLR or a professional studio to pull it off. A new viral trend is sweeping the platform, with users sharing dramatic monochrome portraits that strip away colour to spotlight emotion, light, and texture. The secret behind many of these striking images? AI image generation tools, and the right prompt.

How does it work?

The process is surprisingly simple. Users open Google Gemini Nano Banana or ChatGPT - either on a browser or through the app - upload a reference photo of themselves, type in a descriptive prompt, and let the AI do the rest. The result is a high-quality, editorial-style portrait that can go directly to an Instagram grid. If the first output doesn't hit the mark, users can refine it with follow-up instructions before downloading the final image.
