ComfyUI Node: ImageMagick Local Contrast

ImageMagick Local Contrast:

The ImageMagick Local Contrast node is designed to enhance the local contrast of an image, making details more pronounced and improving the overall visual appeal. This node is particularly useful for bringing out textures and fine details in images, which can be beneficial for artistic purposes or when preparing images for further processing. By adjusting the local contrast, you can make an image appear sharper and more defined without altering the global contrast, thus preserving the overall balance of light and dark areas.

ImageMagick Local Contrast Input Parameters:

image

This parameter represents the input image that you want to apply the local contrast enhancement to. It accepts an image file in a supported format.

radius

The radius parameter controls the size of the area around each pixel that is considered when enhancing local contrast. A larger radius will affect a broader area, leading to more pronounced changes, while a smaller radius will focus on finer details. The value ranges from 0.0 to 1024, with a default of 10. Adjusting this parameter allows you to fine-tune the level of detail enhancement.

strength

The strength parameter determines the intensity of the local contrast enhancement. Higher values will result in stronger contrast adjustments, making details more prominent, while lower values will produce subtler effects. The value ranges from 0.0 to 1024, with a default of 12.5. This parameter is crucial for controlling the overall impact of the local contrast enhancement on the image.

ImageMagick Local Contrast Output Parameters:

IMAGE

The output is an enhanced image with improved local contrast. This image will have more pronounced details and textures, making it visually more appealing and suitable for further artistic or processing tasks.

ImageMagick Local Contrast Usage Tips:

• Experiment with different radius values to find the optimal balance between detail enhancement and overall image appearance.
• Use the strength parameter to control the intensity of the effect. Start with lower values and gradually increase until you achieve the desired level of contrast.
• Combine local contrast enhancement with other image processing techniques, such as sharpening or color adjustments, to create a more polished final image.

ImageMagick Local Contrast Common Errors and Solutions:

ValueError: Unsupported image format

• Explanation: This error occurs when the input image is in a format that is not supported by the node.
• Solution: Ensure that the input image is in a supported format, such as JPEG, PNG, or TIFF.

ValueError: Radius value out of range

• Explanation: This error occurs when the radius parameter is set to a value outside the allowed range (0.0 to 1024).
• Solution: Adjust the radius parameter to a value within the specified range.

ValueError: Strength value out of range

• Explanation: This error occurs when the strength parameter is set to a value outside the allowed range (0.0 to 1024).
• Solution: Adjust the strength parameter to a value within the specified range.
