ComfyUI Node: Color Correction | akatz-loops

Color Correction | akatz-loops| Color Correction | akatz-loops:

The ColorCorrection node in the Color Correction | akatz-loops suite is designed to enhance the visual quality of images by applying adaptive color correction techniques. This node is particularly useful for adjusting the saturation levels of images and optionally applying white balance corrections to achieve a more natural and visually appealing result. By automatically detecting and correcting saturation levels, the node ensures that images do not appear overly dull or excessively vibrant. The optional white balance feature allows for further refinement by adjusting the color temperature, ensuring that whites appear true to life. This node is ideal for batch processing, where consistent color correction settings are required across multiple images, making it a valuable tool for AI artists looking to streamline their workflow and achieve professional-quality results.

Color Correction | akatz-loops| Color Correction | akatz-loops Input Parameters:

image

The image parameter is the input image that you want to process. It serves as the primary data source for the color correction operations performed by the node.

saturation_threshold

The saturation_threshold parameter determines the minimum saturation level required before correction is applied. If the image's saturation is below this threshold, the node will enhance the saturation to meet the desired level. The default value is 0.4, with a range from 0.0 to 1.0, allowing for fine-tuning of the saturation correction process.

max_saturation_factor

The max_saturation_factor parameter sets the upper limit for how much the saturation can be increased. This ensures that the saturation boost remains within a natural range, preventing overly vibrant results. The default value is 1.3, with a range from 1.0 to 2.0, providing flexibility in achieving the desired saturation effect.

enable_white_balance

The enable_white_balance parameter is a boolean option that, when enabled, applies white balance correction to the image. This adjustment helps to neutralize color casts and ensure that whites appear true to life. The default setting is False, meaning white balance correction is not applied unless explicitly enabled.

white_balance_scale_min

The white_balance_scale_min parameter defines the minimum scaling factor for white balance correction. It ensures that the adjustment does not overly reduce the color intensity. The default value is 0.97, with a range from 0.8 to 1.0, allowing for subtle adjustments to the white balance.

white_balance_scale_max

The white_balance_scale_max parameter sets the maximum scaling factor for white balance correction, preventing excessive color enhancement. The default value is 1.03, with a range from 1.0 to 1.2, providing control over the extent of the white balance adjustment.

Color Correction | akatz-loops| Color Correction | akatz-loops Output Parameters:

IMAGE

The IMAGE output parameter represents the processed image after color correction has been applied. This output is the result of the node's operations, providing an image with adjusted saturation and, if enabled, corrected white balance. The output image is ready for further processing or final use, reflecting the enhancements made by the node.

Color Correction | akatz-loops| Color Correction | akatz-loops Usage Tips:

• To achieve a natural look, start with the default saturation threshold and max saturation factor, and adjust incrementally based on the specific needs of your image.
• Enable white balance correction if your image has noticeable color casts or if you want to ensure that whites appear true to life, especially in images with mixed lighting conditions.
• Use batch processing to apply consistent color correction settings across multiple images, saving time and ensuring uniformity in your project.

Color Correction | akatz-loops| Color Correction | akatz-loops Common Errors and Solutions:

Image format not supported

• Explanation: The input image format may not be compatible with the node's processing requirements.
• Solution: Ensure that the input image is in a supported format, such as JPEG or PNG, before processing.

Saturation threshold out of range

• Explanation: The saturation threshold value provided is outside the acceptable range.
• Solution: Adjust the saturation threshold to be within the range of 0.0 to 1.0.

White balance scale values are incorrect

• Explanation: The white balance scale minimum and maximum values are not set correctly.
• Solution: Ensure that white_balance_scale_min is between 0.8 and 1.0, and white_balance_scale_max is between 1.0 and 1.2.
