ComfyUI Node: Fish Eye Effects V2

Fish Eye Effects V2:

FishEyeV2 is a specialized node designed to apply lens effects to images, simulating the visual characteristics of various camera lenses. This node is particularly useful for artists and designers who want to add realistic lens distortions and vignetting effects to their images, enhancing the visual storytelling or artistic expression. By utilizing predefined lens presets, FishEyeV2 allows you to easily replicate the look of different focal lengths, from ultra-wide to telephoto lenses, each with unique distortion, falloff, and vignette properties. This capability provides a powerful tool for creating dynamic and engaging visuals, making it an essential component for those looking to experiment with photographic effects in their digital artwork.

Fish Eye Effects V2 Input Parameters:

LENS_PRESETS

The LENS_PRESETS parameter allows you to select from a variety of predefined lens settings, each simulating a different focal length and its associated visual effects. Options include "14MM Ultra Wide," "24MM Wide," "35MM Standard," "50MM Normal," "85MM Portrait," "100MM Telephoto," "200MM Super Telephoto," and "Custom." Each preset adjusts the distortion, falloff, and vignette to mimic the characteristics of the chosen lens. For example, the "14MM Ultra Wide" preset will apply a significant distortion and vignette effect, while the "200MM Super Telephoto" will have minimal distortion. The "Custom" option allows for manual adjustments, providing flexibility for personalized effects. This parameter is crucial for achieving the desired visual impact and can significantly alter the mood and focus of the image.

Fish Eye Effects V2 Output Parameters:

IMAGE

The IMAGE output parameter represents the processed image with the applied lens effect. This output is the final result of the node's operation, showcasing the selected lens preset's impact on the original image. The output image will exhibit the specific distortion, falloff, and vignette characteristics of the chosen lens, providing a transformed visual that can be used in various artistic or design contexts. Understanding the output is essential for evaluating the effectiveness of the applied lens effect and making any necessary adjustments to achieve the desired artistic outcome.

Fish Eye Effects V2 Usage Tips:

• Experiment with different LENS_PRESETS to find the one that best suits your artistic vision. Each preset offers a unique look, so try several to see how they affect your image.
• Use the "Custom" preset if you want to fine-tune the distortion, falloff, and vignette settings manually. This can be particularly useful if you have a specific effect in mind that isn't covered by the standard presets.
• Consider the context of your image when choosing a lens preset. For example, use wider lenses for landscapes or architectural shots to emphasize depth and perspective, while telephoto lenses can be great for portraits to focus on the subject.

Fish Eye Effects V2 Common Errors and Solutions:

"Invalid lens preset selected"

• Explanation: This error occurs when a lens preset that is not defined in the LENS_PRESETS dictionary is selected.
• Solution: Ensure that you select a valid lens preset from the available options: "14MM Ultra Wide," "24MM Wide," "35MM Standard," "50MM Normal," "85MM Portrait," "100MM Telephoto," "200MM Super Telephoto," or "Custom."

"Image processing failed"

• Explanation: This error might occur if there is an issue with the input image or during the application of the lens effect.
• Solution: Check the input image to ensure it is in a supported format and not corrupted. If the problem persists, try using a different image or adjusting the lens preset settings.
