ComfyUI Node: Fish Eye Effect

Fish Eye Effect:

The FishEyeEffect node is designed to apply a fisheye lens effect to images, creating a distinctive visual distortion that mimics the appearance of viewing through a spherical lens. This effect is often used to create a wide-angle view, giving images a unique and artistic look by bending straight lines and expanding the center of the image while compressing the edges. The node is particularly useful for adding a creative touch to your images, making them stand out with a dynamic and immersive perspective. By leveraging this effect, you can transform ordinary images into captivating visuals that draw the viewer's attention.

Fish Eye Effect Input Parameters:

chromatic_aberration

The chromatic_aberration parameter controls the amount of color distortion applied to the image, simulating the effect of light dispersion through a lens. This parameter can enhance the realism of the fisheye effect by introducing subtle color fringing around the edges of objects. The value is a float, with a default of 0.0, a minimum of 0.0, and a maximum of 0.02. Adjusting this parameter allows you to fine-tune the intensity of the chromatic aberration, with higher values resulting in more pronounced color shifts.

Fish Eye Effect Output Parameters:

IMAGE

The output of the FishEyeEffect node is an IMAGE that has been transformed by the fisheye effect. This output image will exhibit the characteristic distortion of a fisheye lens, with a wide-angle view that bends straight lines and alters the perspective. The resulting image can be used in various creative projects, providing a unique and engaging visual element that enhances the overall aesthetic.

Fish Eye Effect Usage Tips:

• Experiment with the chromatic_aberration parameter to achieve the desired level of color distortion, which can add depth and realism to the fisheye effect.
• Use the FishEyeEffect node to create dynamic and eye-catching visuals for projects that require a unique perspective, such as virtual reality environments or artistic photography.

Fish Eye Effect Common Errors and Solutions:

Image not displaying correctly

• Explanation: This error may occur if the input image dimensions are not compatible with the fisheye transformation process.
• Solution: Ensure that the input image is of a standard size and format that the node can process. Resizing the image to a compatible resolution may resolve the issue.

Chromatic aberration value out of range

• Explanation: This error happens when the chromatic_aberration parameter is set outside its allowed range.
• Solution: Adjust the chromatic_aberration value to be within the specified range of 0.0 to 0.02. Use the slider to ensure precise control over the parameter value.
