ComfyUI Extension: ComfyUI-EsesImageEffectLevels

ComfyUI-EsesImageEffectLevels Introduction

The ComfyUI-EsesImageEffectLevels extension is a powerful tool designed to enhance your image editing capabilities within the ComfyUI environment. This extension provides a real-time levels adjustment feature, allowing you to fine-tune the tonal range of your images and masks directly through an intuitive user interface. By leveraging a GPU-accelerated PyTorch backend, it offers near-instant feedback, making your workflow more efficient and seamless.

This extension is particularly beneficial for AI artists who want to achieve precise tonal adjustments without the complexity of chaining multiple nodes together. It ensures that all your level settings are saved with your workflow, allowing for a non-destructive editing process that can be easily restored upon reloading your project.

How ComfyUI-EsesImageEffectLevels Works

At its core, the ComfyUI-EsesImageEffectLevels extension functions by adjusting the tonal levels of images and masks. Imagine it as a sophisticated dimmer switch for your images, where you can control the brightness and contrast with precision. The extension provides sliders for adjusting the black, mid, and white points of your image, which correspond to the darkest, mid-tone, and brightest areas, respectively.

By moving these sliders, you can enhance the contrast, bring out hidden details, or create specific visual effects. The extension also includes a live histogram that updates in real-time, giving you a visual representation of the tonal distribution in your image. This feature helps you make informed adjustments, ensuring that your artistic vision is accurately realized.
