Google's Nano Banana Pro has slowly gained a reputation for being one of the most popular and powerful AI image generation model out there. The model is capable of not only generating images from scratch using text prompts but taking complex edits to them while retaining original details.
Since the launch of Nano Banana Pro, there have been a number of ways users have found for taking advantage of the new models' capability like creating infographics, product mockups, and even social media thumbnails.
However, Google has shared a new way where you can leverage the full capabilities of its new model. The company says that Nano Banana Pro can be used to bring your old pictures into the 21st century by giving it a simple text prompt.
How to turn your old picture into coloured one?
- Open Gemini app or website. Make sure you are signed in (preferrably from a paid account)
- Select generate image from the menu
- Enter the prompt: “Faithfully restore this image with high fidelity to modern photograph quality, in full color, upscale to 4K”
You can also turn the subsequent image into video, just to see how a famous personality may have looked in their prime. In order to turn the image into video, just go back to Gemini, tap on ‘tools’ and click on ‘create videos’. However, the Gemini video generator (Veo 3.1) is only available to company's paid users. Alternatively, you can also use Grok's Imagine feature to generate videos, while the quality may not be as good as Gemini, Grok can still add a playful twist to your images.
I didn't have access to any black and white pictures, so I instead borrowed a few pictures of Mahatma Gandhi from the HT archive and turned them into colourful ones with Nano Banana Pro.
What's new with Nano Banana Pro?
Nano Banana Pro comes with integration to Google Search and is powered by the tech giant's latest Gemini 3 Pro model. This means that Nano Banana Pro doesn't need to be given a specific text prompt for generating infographics and the model is capable of fetching information from the web and compile it to generate the relevant infographic.
So you can just tell Nano Banana Pro to generate an infographic for a recipe of tea or any other food of your choice. Recently, I used Gemini to look me up on the internet and then subsequently asked nano Banana Pro to generate an infographic on the kind of work I do. You can see the result below.
