ComfyUI Extension: ComfyUI-EsesImageEffectCurves

ComfyUI-EsesImageEffectCurves Introduction

The ComfyUI-EsesImageEffectCurves extension is a powerful tool designed to enhance your image editing capabilities within the ComfyUI environment. This extension introduces a real-time curves adjustment feature that allows you to fine-tune the tonal range of images and masks directly from the user interface. By leveraging a GPU-accelerated PyTorch backend, it provides near-instant feedback, making your workflow more efficient and intuitive. Whether you're looking to adjust the overall brightness, contrast, or color balance, this extension simplifies the process, eliminating the need to chain multiple nodes together. It ensures that all your curve settings are saved and restored with your workflow, offering a seamless and non-destructive editing experience.

How ComfyUI-EsesImageEffectCurves Works

At its core, ComfyUI-EsesImageEffectCurves operates by allowing you to manipulate the tonal curves of your images. Imagine the tonal curve as a flexible line that represents the brightness levels of your image. By adjusting this line, you can control how light or dark different parts of your image appear. The extension provides an interactive curve editor where you can add, remove, and move points on this line to achieve the desired effect. This process is akin to adjusting the volume on a stereo, where you can increase or decrease the intensity of specific tones. The extension's real-time feedback ensures that you can see the effects of your adjustments immediately, making it easier to achieve the perfect look.

ComfyUI-EsesImageEffectCurves Features

• Interactive Curve Editor: This feature allows you to see a live preview of the curve directly on the node. As you drag points, the curve updates in real-time, providing immediate visual feedback. You can add and remove points for detailed adjustments and move them along both the X and Y axes to create effects like level inversion or to enhance contrast.
• Multi-Channel Adjustments: You can apply curves to the combined RGB channels for overall tonal control or isolate adjustments to individual Red, Green, or Blue channels for precise color grading. Additionally, you can apply a separate curve to an input mask or adjust saturation and luma curves.
• State Serialization: All your curve adjustments are saved with your workflow, ensuring that your settings persist even after refreshing the browser page. This feature also includes the node's manually resized dimensions.
• Quality of Life Features: The node automatically resizes to fit the aspect ratio of the input image. It includes a "Reset Curve" button to revert the selected channel's curve to a linear state and a "Reset Node Size" button to re-trigger the auto-sizing logic.
