ComfyUI Extension: ComfyUI-EsesImageLensEffects

ComfyUI-EsesImageLensEffects Introduction

The ComfyUI-EsesImageLensEffects extension is a versatile tool designed to enhance your digital artwork by simulating various lens effects. This extension integrates multiple lens characteristics into a single, user-friendly node within ComfyUI, a popular interface for AI-driven image processing. By using this extension, you can add realistic or artistic lens distortions, chromatic aberrations, and vignettes to your images, all while maintaining control over the final output. Whether you're looking to add subtle enhancements or dramatic effects, this extension provides the tools you need to elevate your creative projects.

How ComfyUI-EsesImageLensEffects Works

At its core, ComfyUI-EsesImageLensEffects leverages the power of scikit-image and PyTorch to perform complex image transformations. Imagine looking through a camera lens that can bend and color-shift light in various ways. This extension mimics those effects digitally, allowing you to manipulate images as if you were adjusting a physical lens. By altering parameters such as distortion and color fringing, you can create effects ranging from subtle lens imperfections to exaggerated artistic styles. The extension processes images in a sequence, applying each effect in a logical order to ensure a cohesive final result.

ComfyUI-EsesImageLensEffects Features

Lens Distortion & Chromatic Aberration

• k1_master_distortion: This control adjusts the primary distortion of the image, either bulging it outwards (barrel distortion) or squeezing it inwards (pincushion distortion). This effect can add depth or a unique perspective to your images.
• Channel-specific aberration: These controls allow you to offset the distortion for each color channel (Red, Green, Blue), creating a color fringing effect that can mimic the imperfections seen in real-world lenses.
• radial_exponent: This parameter fine-tunes how the distortion effect spreads from the center of the image, allowing for precise control over the intensity and reach of the distortion.

Post-Process Scaling

• post_process_scale: This slider lets you zoom in on the image, effectively cropping out any unwanted edges or stretched pixels that may result from the distortion effects. It's a quick way to reframe your image without losing quality.

Flexible Vignette

• vignette_amount: Adjusts the intensity of the vignette, either darkening or lightening the edges of the image to draw focus to the center.
• vignette_size: Controls the size of the vignette, allowing you to decide how much of the image is affected.
• vignette_falloff: Determines the softness of the vignette's transition, from a hard edge to a gentle fade.
• fit_vignette_to_frame: A toggle that lets you choose between a circular vignette or one that matches the aspect ratio of your image.

Flexible Edge Handling & Quality

• interpolation_mode: Choose the resampling quality for your image, with options like Bilinear and Bicubic, to ensure the best visual results.
• fill_mode: Defines how new pixels are handled at the image boundaries, ensuring a seamless look.

ComfyUI-EsesImageLensEffects Models

Currently, the extension does not include different models. It focuses on providing a comprehensive set of features within a single node to achieve a wide range of lens effects.

What's New with ComfyUI-EsesImageLensEffects

• Version 1.0.1 (2025.7.10): This update included minor documentation improvements to help users better understand the extension's capabilities.
• Version 1.0.0 (2025.6.27): The initial release introduced the full suite of lens effects, providing a robust toolset for AI artists to enhance their images.

Troubleshooting ComfyUI-EsesImageLensEffects

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

• Image Distortion Not Visible: Ensure that the k1_master_distortion and channel-specific aberration settings are adjusted to noticeable levels. Start with small increments to see the effect.
• Vignette Not Appearing: Check the vignette_amount and vignette_size settings. Ensure that the vignette is not too subtle by increasing the intensity or size.
• Unexpected Image Quality: Experiment with different interpolation_mode settings to find the best quality for your image. Bicubic interpolation often provides smoother results.
