ComfyUI Node: EnhanceImage

EnhanceImage:

The EnhanceImage node is designed to improve the visual quality of images by adjusting their contrast. This node is particularly useful for AI artists who want to enhance the depth and clarity of their images, making them more visually appealing. By fine-tuning the contrast, you can bring out details that might otherwise be lost, creating a more dynamic and engaging image. This node processes images in batches, ensuring that multiple images can be enhanced simultaneously, which is a significant time-saver for large projects.

EnhanceImage Input Parameters:

image

This parameter accepts a list of images that you want to enhance. The images should be in a format that the node can process, typically as tensors. The node will apply the specified contrast enhancement to each image in the list.

contrast

This parameter controls the level of contrast enhancement applied to the images. It is a floating-point value with a default of 0.5, a minimum of 0, and a maximum of 10. The contrast value can be adjusted in increments of 0.01 using a slider. Increasing the contrast value will make the dark areas darker and the bright areas brighter, thereby enhancing the overall depth and detail of the image.

EnhanceImage Output Parameters:

IMAGE

The output is a list of images that have been processed and enhanced based on the specified contrast settings. These images will have improved visual quality, with enhanced depth and clarity, making them more suitable for various artistic and professional applications.

EnhanceImage Usage Tips:

• To achieve a subtle enhancement, start with a lower contrast value (e.g., 0.5) and gradually increase it until you achieve the desired effect.
• For images that are too flat or lack depth, a higher contrast value (e.g., 2.0 or above) can significantly improve their visual appeal.
• Batch process multiple images to save time and ensure consistency across your project.

EnhanceImage Common Errors and Solutions:

"Invalid image format"

• Explanation: The input images are not in a format that the node can process.
• Solution: Ensure that the images are in a compatible format, typically as tensors, before inputting them into the node.

"Contrast value out of range"

• Explanation: The specified contrast value is outside the acceptable range (0 to 10).
• Solution: Adjust the contrast value to be within the specified range using the slider.

"Empty image list"

• Explanation: The input image list is empty, so there are no images to process.
• Solution: Provide a list of images to the node for processing. Ensure that the list is not empty.
