3. How to Use Nano Banana 2 for Photorealism

To get ultra realistic results, follow these rules:

3.1 Define Lighting Clearly

Nano Banana 2 responds strongly to lighting descriptions:

• soft natural light
• cinematic rim light
• overcast sky diffusion
• neon reflections

3.2 Add Camera & Lens Metadata

For realism, always specify:

• 50mm lens
• f1.8 aperture
• shallow depth of field
• high dynamic range

3.3 Describe Composition

Mention angle & subject placement.
Example: close-up portrait, subject centered, clean gradient background.

3.4 Request Resolution

Always include:
“4K resolution, hyper-detailed texture”
