Documentation for LayerFilter: LightLeak Node

Overview

The LayerFilter: LightLeak node is a feature of ComfyUI, a user interface tool for manipulating images. This node is designed to simulate a "light leak" effect on images, providing a creative way to add visual interest and enhance your images by mimicking the unpredictable light exposure found in film photography.

Functionality

The LayerFilter: LightLeak node applies a light leak effect to one or more images by overlaying pre-defined light patterns. It allows you to customize the application of the light leak based on parameters like opacity, hue, and saturation, as well as selecting the corner placement of the light leak.

Inputs

The LayerFilter: LightLeak node accepts the following inputs:

• Image: The primary input that requires an image (or a batch of images) which the light leak effect will be applied to.

• Light: A selection from a list of 32 predefined light leak patterns. Options range from '1' to '32', with an additional 'random' option which selects a pattern at random.

• Corner: Specifies the corner of the image where the light leak effect will be applied. This can be 'left_top', 'right_top', 'left_bottom', or 'right_bottom'.

• Hue: Adjusts the hue of the light leak effect. This is an integer input with a range from -255 to 255.

• Saturation: Modifies the saturation level of the light effect. This is also an integer input with a range from -255 to 255.

• Opacity: Determines the transparency of the light leak. This value is an integer ranging from 0 to 100, where 100 represents full opacity.

Outputs

The node outputs a modified version of the input image(s) with the light leak effect applied. The output is compatible with further processing or display within the ComfyUI interface.

Integration in ComfyUI Workflows

The LayerFilter: LightLeak node can seamlessly integrate into various image processing workflows within ComfyUI, offering users the ability to:

• Enhance photographs with a nostalgic, artistic flair similar to traditional film cameras.
• Develop visually appealing images for creative projects or photo edits.
• Experiment with different aesthetic styles by adjusting parameters to achieve the desired visual effect.

Special Features and Considerations

• Random Light Selection: Users can choose 'random' for the light input to allow the node to automatically select a light pattern, adding an element of unpredictability and creativity.

• Customizable Parameters: Fine-tune the visual outcome by adjusting hue, saturation, and opacity, giving users control over how subtle or pronounced the light leak effect is.

• Performance: The node processes images in batches, which is efficient for workflows that involve multiple images.

Conclusion

The LayerFilter: LightLeak node is a powerful tool for enthusiasts and professionals looking to enhance their images with simulated light leak effects. By offering a range of customizable options, it provides users with creative freedom while maintaining efficiency for both single and batch image processing tasks within the ComfyUI environment.
