With the rapid development of AI photo editing technology, more and more users are paying attention to Nano Banana. Especially in scenarios such as old photo restoration and portrait detail enhancement, Nano Banana has gradually become an important tool for Photoshop users.

So what exactly is Nano Banana, what can Nano Banana Pro do, and how effective is it for old photo restoration?

1、What Is Nano Banana?

Nano Banana is an AI-based photo editing solution focused on image reconstruction and detail enhancement. It is designed to improve blurred photos, restore damaged old photos, and rebuild facial details in a natural way rather than relying on simple sharpening.

Unlike traditional Photoshop filters, Nano Banana does not simply increase sharpness. Instead, it analyzes image content through AI models and regenerates more reasonable and realistic details based on image structure.

Because of this approach, Nano Banana is widely used in old photo restoration workflows.

2、What Photo Problems Can Nano Banana Solve?

In real-world use, Nano Banana is commonly applied to several types of old photo restoration tasks.

（1）Old Photo Blur Restoration

For old photos with low resolution or poor scan quality, Nano Banana can significantly improve clarity while keeping the image looking natural and balanced.

（2）Portrait Detail Enhancement

When old photos suffer from missing facial details such as blurred eyes, noses, or mouths, Nano Banana rebuilds these features based on facial structure instead of applying aggressive sharpening.

（3）Noise and Scratch Reduction

Common issues in old photos, including noise, grain, and minor scratches, can also be effectively reduced through Nano Banana’s AI restoration process.
