ComfyUI Node: Highlight Shadow Brightness

Highlight Shadow Brightness:

The HighlightShadowBrightnessNode is a powerful tool designed to enhance and adjust the visual dynamics of an image by manipulating its highlights, shadows, and overall brightness. This node is particularly beneficial for AI artists who wish to fine-tune the lighting and contrast of their images, allowing for more dramatic or subtle effects as desired. By adjusting the highlights, you can emphasize the brighter areas of an image, while modifying the shadows can bring out details in the darker regions. The brightness adjustment provides a global change to the image's luminance, making it either brighter or darker overall. This node is essential for achieving the perfect balance of light and shadow, enhancing the mood and depth of your artwork.

Highlight Shadow Brightness Input Parameters:

image

The image parameter is the input image that you want to process. It serves as the base for all subsequent adjustments made by the node. This parameter is required and should be provided in a compatible image format.

highlight

The highlight parameter controls the intensity of the brighter areas in the image. It ranges from -10.0 to 10.0, with a default value of 0. Increasing this value will enhance the highlights, making them more pronounced, while decreasing it will reduce their intensity. This adjustment is crucial for emphasizing or softening the bright spots in your image.

shadow

The shadow parameter adjusts the darker areas of the image. Like the highlight parameter, it ranges from -10.0 to 10.0, with a default of 0. Increasing the shadow value will lighten the dark areas, revealing more detail, while decreasing it will deepen the shadows, adding contrast. This parameter is key for controlling the depth and detail in shadowed regions.

brightness

The brightness parameter affects the overall luminance of the image. It also ranges from -10.0 to 10.0, with a default value of 0. A higher brightness value will make the entire image lighter, while a lower value will darken it. This global adjustment is useful for setting the general light level of your image.

Highlight Shadow Brightness Output Parameters:

image

The image output is the processed image after applying the highlight, shadow, and brightness adjustments. This output reflects the changes made based on the input parameters, providing a visually enhanced version of the original image. The output image retains the same format as the input, ready for further processing or final use.

Highlight Shadow Brightness Usage Tips:

• To achieve a balanced look, start with small adjustments to the highlight and shadow parameters and gradually increase them to see their effects.
• Use the brightness parameter to correct the overall exposure of your image, especially if the original image is too dark or too bright.

Highlight Shadow Brightness Common Errors and Solutions:

Image format not supported

• Explanation: The input image is not in a compatible format.
• Solution: Ensure that the image is in a supported format such as JPEG or PNG before inputting it into the node.

Value out of range

• Explanation: One of the input parameters is set outside its allowed range.
• Solution: Check that the highlight, shadow, and brightness values are within the -10.0 to 10.0 range and adjust them accordingly.
