ComfyUI Extension: ComfyUI-EsesImageEffectBloom

ComfyUI-EsesImageEffectBloom Introduction

The ComfyUI-EsesImageEffectBloom extension is a powerful tool designed to enhance your digital artwork by adding a realistic bloom effect to your images. This effect mimics the natural glow that occurs around bright light sources in photography, creating a soft, ethereal aura that can add depth and atmosphere to your work. Whether you're looking to highlight specific areas of your image or create a dreamy, luminous effect, this extension provides the tools you need to achieve your artistic vision. By leveraging GPU-accelerated PyTorch technology, it ensures real-time performance, making it a valuable addition to your creative toolkit.

How ComfyUI-EsesImageEffectBloom Works

At its core, the ComfyUI-EsesImageEffectBloom extension works by isolating the brightest parts of an image and applying a glow effect to them. Imagine taking a photograph of a cityscape at night; the streetlights and building windows would naturally emit a soft glow. This extension replicates that effect by identifying the highlights in your image and enhancing them with a customizable blur. The process involves setting thresholds to determine which parts of the image are considered highlights, applying a blur to these areas, and then blending the result back into the original image. This approach allows you to control the intensity and spread of the glow, giving you the flexibility to create subtle or dramatic effects.

ComfyUI-EsesImageEffectBloom Features

The extension offers a range of features that allow you to customize the bloom effect to suit your artistic needs:

• Controllable Highlight Isolation:
• low_threshold: This setting allows you to define the minimum brightness level that should be considered a highlight. By adjusting this, you can control which parts of your image will glow.
• high_threshold: This setting lets you specify the maximum brightness level for highlights, giving you fine control over the range of brightness that will be affected.
• Glow Controls:
• blur_type: Choose between a gaussian blur for a high-quality, smooth glow or a box blur for a more performance-efficient effect.
• blur_radius: Adjust the size and softness of the glow. A smaller radius results in a tighter glow, while a larger radius creates a more diffuse effect.
• highlights_brightness: Increase the intensity of the glow before it is blended back into the image, allowing for a more pronounced light emission.
• Compositing Options:
• blend_mode: Select from various blend modes such as screen, add, overlay, soft_light, and hard_light to determine how the glow interacts with the original image.
• fade: Use this slider to adjust the overall opacity of the bloom effect, controlling its visibility and impact on the final image.

ComfyUI-EsesImageEffectBloom Models

Currently, the extension does not include different models. It focuses on providing a highly customizable bloom effect through its various settings and controls.

What's New with ComfyUI-EsesImageEffectBloom

The extension has undergone several updates to enhance its functionality and user experience:

• Version 1.1.1 (2025.7.10): Minor updates to the documentation to improve clarity and usability.
• Version 1.1.0 (2025.6.27): Introduced an optional streaks blur mode, offering a new way to apply the bloom effect with a unique visual style.
• Version 1.0.0 (2025.6.25): Initial release, providing a comprehensive set of tools for applying bloom effects to images.

Troubleshooting ComfyUI-EsesImageEffectBloom

If you encounter issues while using the extension, here are some common problems and their solutions:

• Slow Performance: If the bloom effect is rendering slowly, especially with large images, try reducing the image size or using the box blur type for better performance.
• No Visible Effect: Ensure that your image has distinct highlights. Adjust the low_threshold and high_threshold settings to better isolate the bright areas.
• Overly Intense Glow: If the glow is too strong, reduce the highlights_brightness or adjust the fade slider to decrease the effect's intensity.
