ComfyUI Node: LayerColor: AutoBrightness

LayerColor: AutoBrightness:

The LayerColor: AutoBrightness node is designed to automatically adjust the brightness of an image, enhancing its visual appeal and ensuring optimal exposure. This node is particularly useful for AI artists who want to quickly and efficiently improve the brightness levels of their images without manually tweaking each parameter. By leveraging this node, you can achieve a balanced and well-lit image, which is crucial for creating visually striking artwork. The AutoBrightness node intelligently analyzes the image and applies the necessary adjustments to enhance its overall brightness, making it an essential tool for any AI artist looking to streamline their workflow and produce high-quality images.

LayerColor: AutoBrightness Input Parameters:

image

The image parameter is the primary input for the node, representing the image that you want to adjust. This parameter is required and must be provided for the node to function. The image should be in a compatible format that the node can process.

strength

The strength parameter controls the intensity of the brightness adjustment. It is an integer value with a default of 75, a minimum of 0, and a maximum of 100. Adjusting this parameter allows you to fine-tune how much the brightness of the image is altered, with higher values resulting in more significant adjustments.

saturation

The saturation parameter adjusts the color saturation of the image. It is an integer value with a default of 8, a minimum of -255, and a maximum of 255. This parameter allows you to enhance or reduce the vibrancy of the colors in the image, with positive values increasing saturation and negative values decreasing it.

mask

The mask parameter is optional and allows you to specify a mask for selective brightness adjustment. If provided, the node will only adjust the brightness of the areas defined by the mask. This can be useful for targeting specific regions of the image while leaving other areas unchanged.

LayerColor: AutoBrightness Output Parameters:

image

The image output parameter represents the adjusted image after the brightness correction has been applied. This output is crucial as it provides the final result of the node's processing, allowing you to see the enhanced image with the applied brightness adjustments.

LayerColor: AutoBrightness Usage Tips:

• To achieve a subtle brightness enhancement, start with a lower strength value and gradually increase it until you reach the desired effect.
• Use the saturation parameter to balance the color vibrancy after adjusting the brightness, ensuring that the image does not appear washed out or overly saturated.
• If you need to adjust the brightness of specific areas in the image, provide a mask to target those regions selectively.

LayerColor: AutoBrightness Common Errors and Solutions:

Image format not supported

• Explanation: The provided image is in a format that the node cannot process.
• Solution: Ensure that the image is in a compatible format, such as JPEG or PNG, before inputting it into the node.

Strength value out of range

• Explanation: The strength parameter value is outside the allowed range of 0 to 100.
• Solution: Adjust the strength value to be within the specified range to ensure proper functionality.

Saturation value out of range

• Explanation: The saturation parameter value is outside the allowed range of -255 to 255. - Solution: Adjust the saturation value to be within the specified range to ensure proper functionality.

Mask not applied correctly

• Explanation: The provided mask is not correctly formatted or does not match the dimensions of the image.
• Solution: Verify that the mask is correctly formatted and matches the dimensions of the image to ensure proper selective adjustment.
