ComfyUI Node: Recenter

Recenter:

The Recenter node is designed to adjust the latent space of your AI-generated images, providing a way to fine-tune the color balance and overall appearance of the output. By manipulating the latent variables, this node allows you to subtly or significantly alter the color properties of your images, ensuring they meet your artistic vision. The primary goal of the Recenter node is to offer a flexible and intuitive method for color correction and enhancement, making it an essential tool for AI artists looking to refine their creations.

Recenter Input Parameters:

latent

This parameter represents the latent space input that the node will process. The latent space is a compressed representation of the image data, which the node will adjust based on the other input parameters.

strength

This parameter controls the intensity of the recentering effect. It ranges from 0.0 to 1.0, with a default value of 0.0. A higher strength value will result in a more pronounced adjustment to the latent space, while a lower value will make the changes more subtle.

C

This parameter adjusts the cyan component of the color balance. It ranges from -1.00 to 1.00, with a default value of 0.01. Positive values increase the cyan component, while negative values decrease it.

M

This parameter adjusts the magenta component of the color balance. It ranges from -1.00 to 1.00, with a default value of 0.50. Positive values increase the magenta component, while negative values decrease it.

Y

This parameter adjusts the yellow component of the color balance. It ranges from -1.00 to 1.00, with a default value of -0.13. Positive values increase the yellow component, while negative values decrease it.

K

This parameter adjusts the black component of the color balance. It ranges from -1.00 to 1.00, with a default value of 0.00. Positive values increase the black component, while negative values decrease it.

Recenter Output Parameters:

LATENT

The output is the adjusted latent space, which has been modified according to the input parameters. This adjusted latent space can then be used to generate images with the desired color balance and appearance.

Recenter Usage Tips:

• Experiment with different strength values to find the right balance for your image adjustments. Start with a lower value and gradually increase it to see the effect.
• Use the C, M, Y, and K parameters to fine-tune the color balance. Small adjustments can make a significant difference, so make changes incrementally.
• Combine the Recenter node with other nodes in your workflow to achieve more complex and refined results.

Recenter Common Errors and Solutions:

ValueError: Input latent space is not valid

• Explanation: This error occurs when the input latent space is not in the expected format or is corrupted.
• Solution: Ensure that the input latent space is correctly generated and passed to the Recenter node. Verify the integrity of the latent data before processing.

TypeError: Strength parameter must be a float

• Explanation: This error occurs when the strength parameter is not a float value.
• Solution: Check that the strength parameter is set to a float value within the range of 0.0 to 1.0. Adjust the input if necessary.

IndexError: LUTs list index out of range

• Explanation: This error occurs when the LUTs list is not properly initialized or accessed.
• Solution: Ensure that the C, M, Y, and K parameters are correctly set and that the LUTs list is properly initialized in the node's hook function.
