ComfyUI Extension: cd-tuner_negpip-ComfyUI

cd-tuner_negpip-ComfyUI Introduction

The cd-tuner_negpip-ComfyUI extension is a powerful tool designed to enhance your AI-generated images by allowing you to fine-tune color tones and detailing levels directly within the generation process. This extension integrates two key functionalities from the original webUI extensions created by hako-mikan:

1. CD Tuner: Adjusts color tones and detailing levels.
2. NegPiP (Negative Prompt in Prompt): Implements negative weights in prompts to refine the output.

By using this extension, AI artists can achieve more precise control over the visual aspects of their generated images, leading to higher quality and more customized results.

How cd-tuner_negpip-ComfyUI Works

CD Tuner

The CD Tuner part of the extension allows you to modify the color tones and detailing levels during the image generation process. Unlike post-processing tools, it intervenes during the generation, ensuring that the adjustments are more naturally integrated into the final image. This is particularly useful for improving the quality of images generated with high-resolution fixes (Hires.fix).

NegPiP

NegPiP enables the use of negative weights within prompts. This means you can specify elements you want to minimize or exclude from the generated image by assigning them negative values. This feature enhances the flexibility and precision of prompt-based image generation.

cd-tuner_negpip-ComfyUI Features

CD Tuner Features

• Detail1, Detail2: Adjust the amount of detailing. Positive values increase detailing and noise, while negative values make the image flatter and slightly blurry.
• Contrast and Brightness: Modify the contrast and brightness, which also affects the detailing. Adjustments can be made during or after the generation process.
• Color1, Color2, Color3: Fine-tune the color tones. For example, setting Cyan-Red to a negative value will enhance cyan tones, while a positive value will enhance red tones.
• Saturation: Adjust the saturation levels to make colors more or less intense.
• Hr-Detail1, Hr-Detail2, Hires-Scaling: Optimize settings for high-resolution fixes. These parameters allow for different values during Hires.fix to achieve better results.

NegPiP Features

• Negative Weights in Prompts: Use negative values in prompts to reduce or eliminate specific elements. For example, (black:-1.8) will reduce the presence of black in the image.
• Positive Weights in Negative Prompts: Apply positive weights within negative prompts to enhance certain elements.

cd-tuner_negpip-ComfyUI Models

This extension does not introduce new models but enhances the functionality of existing models by providing more control over the generation process. It is compatible with both 1.X and 2.X series models, making it versatile for various use cases.
