SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a standardized, controlled approach to generating hyper-realistic images by enforcing a strict, parameterized JSON prompt schema, removing biases and ensuring reproducible outputs.

Core Features & Use Cases

  • Strict JSON prompt schema: Enforces fields such as task, output, image_quality_simulation, subject, environment, and controlnet to produce deterministic prompts.
  • Deterministic image generation: By explicit camera parameters and negative prompts, reduces variability and bias.
  • Use Case: Generate ultra-detailed images for product visuals, concept art, or promotional materials with reproducible results.

Quick Start

Provide a detailed, schema-conforming JSON prompt and pass it to the generate_image tool to produce the image.

Frequently Asked Questions about banana2

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate hyper-realistic images with deterministic outputs?

Generate hyper-realistic images with deterministic outputs by enforcing a strict, parameterized JSON prompt schema that specifies camera parameters, negative prompts, and safety constraints to reduce variability and bias.

What camera parameters can I control for photorealistic image generation?

For photorealistic image generation, you can satisfy exact camera parameters including focal length, aperture, and ISO alongside explicit negative prompts within the JSON schema to ensure consistent optical realism.

How do I use a JSON prompt schema for product visuals and scene renders?

Use a JSON prompt schema for product visuals and scene renders by populating fields like task, output, image_quality_simulation, subject, environment, and controlnet to produce deterministic, ultra-detailed promotional materials.

Does this image generation approach work with Nano Banana 2 models?

Yes, this approach works with Nano Banana 2 or compatible models by passing the detailed, schema-conforming JSON prompt to the generate_image tool to produce hyper-realistic images.

Why do my hyper-realistic image prompts produce inconsistent results?

Hyper-realistic image prompts produce inconsistent results due to variability and bias, which you reduce by enforcing a strict JSON prompt schema with explicit camera parameters and negative prompts for deterministic image generation.

When do I need a strict JSON schema for image generation?

You need a strict JSON schema for image generation when you require standardized, controlled approaches to produce reproducible outputs for ultra-detailed portraits, product visuals, or scene renders without biases.
