ComfyUI Node: ImageEffectsLensChromaticAberration

ImageEffectsLensChromaticAberration:

The ImageEffectsLensChromaticAberration node is designed to simulate the chromatic aberration effect commonly seen in photography and cinematography. Chromatic aberration occurs when a lens fails to focus all colors to the same convergence point, resulting in a slight color fringing around the edges of objects. This node allows you to add this realistic lens distortion effect to your images, enhancing the visual appeal and authenticity of your AI-generated artwork. By manipulating the parameters, you can control the intensity and characteristics of the chromatic aberration, giving you creative flexibility to achieve the desired artistic effect.

ImageEffectsLensChromaticAberration Input Parameters:

images

This parameter takes the input image(s) that you want to apply the chromatic aberration effect to. The images should be in a compatible format and resolution for processing.

lens_shape

Defines the shape of the lens, which influences the pattern and distribution of the chromatic aberration effect. Different shapes can create unique visual distortions.

lens_edge

Specifies the edge behavior of the lens effect. Options might include "around" for a radial effect or "symmetric" for a balanced effect. This parameter affects how the chromatic aberration is applied across the image.

lens_curvy

Controls the curvature of the lens, impacting the intensity and spread of the chromatic aberration. Higher values result in more pronounced curvature and distortion.

lens_zoom

Adjusts the zoom level of the lens effect. Increasing this value can enhance the chromatic aberration by simulating a closer or more magnified view through the lens.

lens_aperture

Determines the aperture size of the lens, affecting the depth of field and the extent of the chromatic aberration. A larger aperture can create a more significant effect.

blur_intensity

Sets the intensity of the blur applied to the chromatic aberration effect. Higher values result in a more blurred and diffused color fringing.

ImageEffectsLensChromaticAberration Output Parameters:

result

The primary output is the processed image(s) with the chromatic aberration effect applied. This output retains the original resolution and format of the input image(s) but includes the added visual distortion.

mask

A mask that represents the areas of the image where the chromatic aberration effect has been applied. This can be useful for further post-processing or compositing tasks.

ImageEffectsLensChromaticAberration Usage Tips:

• Experiment with different lens_shape and lens_edge settings to achieve unique visual effects that suit your artistic vision.
• Use the lens_curvy and lens_zoom parameters to fine-tune the intensity and spread of the chromatic aberration, creating subtle or dramatic effects as needed.
• Adjust the blur_intensity to control the sharpness of the color fringing, balancing between a crisp or a more diffused look.

ImageEffectsLensChromaticAberration Common Errors and Solutions:

ValueError: Not existing lens_edge parameter.

• Explanation: This error occurs when an invalid value is provided for the lens_edge parameter.
• Solution: Ensure that the lens_edge parameter is set to a valid option, such as "around" or "symmetric".

Unsupported method.

• Explanation: This error is raised when an unsupported method is specified for processing the image.
• Solution: Verify that the method parameter is set to a supported value, such as "dilate" or "filter".
