ComfyUI Node: LayerColor: Exposure

LayerColor: Exposure:

The LayerColor: Exposure node is designed to adjust the exposure levels of an image, allowing you to brighten or darken the image by modifying its exposure value. This node is particularly useful for enhancing the visual appeal of your images by making them appear more vivid or subdued, depending on your artistic needs. By manipulating the exposure, you can bring out details in the shadows or highlights, creating a more balanced and visually appealing image. The node processes each image individually, ensuring that the adjustments are applied consistently across all images in a batch.

LayerColor: Exposure Input Parameters:

image

This parameter accepts the image(s) you want to adjust. The input should be in the form of an image tensor, which the node will process to apply the exposure correction. The image tensor should be in the format expected by the node, typically a 3D or 4D tensor representing the image data.

exposure

The exposure parameter controls the level of exposure adjustment applied to the image. It accepts integer values ranging from -100 to 100, with a default value of 20. A positive value increases the exposure, making the image brighter, while a negative value decreases the exposure, making the image darker. The step size for this parameter is 1, allowing for fine-grained control over the exposure adjustment.

LayerColor: Exposure Output Parameters:

image

The output is the adjusted image(s) with the applied exposure correction. The output is in the form of an image tensor, similar to the input format. This tensor represents the image data after the exposure adjustment, ready for further processing or final output.

LayerColor: Exposure Usage Tips:

• To brighten an image, increase the exposure value. Start with small increments to avoid overexposure.
• To darken an image, decrease the exposure value. This can help bring out details in overly bright areas.
• Use the exposure adjustment in combination with other color correction nodes for more comprehensive image enhancement.

LayerColor: Exposure Common Errors and Solutions:

Image tensor format error

• Explanation: The input image tensor is not in the expected format.
• Solution: Ensure that the input image tensor is correctly formatted as a 3D or 4D tensor representing the image data.

Exposure value out of range

• Explanation: The exposure value provided is outside the acceptable range of -100 to 100.
• Solution: Adjust the exposure value to be within the specified range to ensure proper functioning of the node.

Processing error

• Explanation: An error occurred during the processing of the image.
• Solution: Check the input image tensor for any anomalies and ensure that the node is correctly configured. If the issue persists, try processing a different image to isolate the problem.
