ComfyUI Node: LayerColor: LUT Apply

LayerColor: LUT Apply:

The "LayerColor: LUT Apply" node is designed to enhance your images by applying a Look-Up Table (LUT) for color correction. This node allows you to transform the colors of your images based on predefined LUT files, which can significantly alter the mood, tone, and overall aesthetic of your artwork. By using this node, you can achieve professional-grade color grading effects with ease, making your images more visually appealing and consistent with your desired style. The node supports different color spaces, ensuring flexibility and precision in color correction.

LayerColor: LUT Apply Input Parameters:

image

This parameter accepts the image(s) you want to process. The input should be in the form of an image tensor. The node will apply the selected LUT to each image in the batch, transforming their colors according to the LUT file.

LUT

This parameter specifies the Look-Up Table (LUT) file to be used for color correction. LUTs are predefined mappings that adjust the colors of your image to achieve a specific look or style. You can choose from a list of available LUTs, each providing a unique color transformation.

color_space

This parameter determines the color space in which the LUT will be applied. You can choose between 'linear' and 'log' color spaces. The 'linear' option applies the LUT in a linear color space, while the 'log' option applies it in a logarithmic color space, which can be useful for certain types of images or desired effects.

LayerColor: LUT Apply Output Parameters:

image

The output is the processed image(s) with the LUT applied. The resulting image tensor will have the same dimensions as the input but with colors transformed according to the selected LUT and color space. This output can be used directly in your artwork or further processed with other nodes.

LayerColor: LUT Apply Usage Tips:

• Experiment with different LUTs to find the one that best matches the mood and style you want to achieve in your image.
• Use the 'log' color space option if you are working with images that require a more nuanced color transformation, such as those with high dynamic range.
• Combine this node with other color correction nodes to fine-tune the final look of your image.

LayerColor: LUT Apply Common Errors and Solutions:

LUT file not found

• Explanation: The specified LUT file could not be located in the LUT dictionary.
• Solution: Ensure that the LUT file name is correctly spelled and that it exists in the LUT dictionary.

Invalid color space

• Explanation: The selected color space is not recognized.
• Solution: Choose either 'linear' or 'log' as the color space option.

Image tensor dimension mismatch

• Explanation: The input image tensor does not have the expected dimensions.
• Solution: Verify that the input image tensor is correctly formatted and has the appropriate dimensions for processing.
