ComfyUI Node: ImageEffectsAdjustment

ImageEffectsAdjustment:

The ImageEffectsAdjustment node is designed to provide comprehensive control over various image properties, allowing you to fine-tune the visual aspects of your images. This node is particularly useful for adjusting brightness, contrast, saturation, hue, gamma, sharpness, and individual color channels (red, green, blue). By leveraging these adjustments, you can enhance the visual appeal of your images, correct color imbalances, and achieve specific artistic effects. The node processes each image individually, ensuring that the adjustments are applied consistently across all images in a batch.

ImageEffectsAdjustment Input Parameters:

images

This parameter accepts a batch of images that you want to adjust. Each image in the batch will be processed individually to apply the specified adjustments.

brightness

This parameter controls the brightness of the image. A value of 1.0 means no change, values greater than 1.0 increase brightness, and values less than 1.0 decrease brightness. Adjusting brightness can help in making the image appear lighter or darker.

contrast

This parameter adjusts the contrast of the image. A value of 1.0 means no change, values greater than 1.0 increase contrast, and values less than 1.0 decrease contrast. Higher contrast makes the dark areas darker and the bright areas brighter.

saturation

This parameter controls the saturation of the image. A value of 1.0 means no change, values greater than 1.0 increase saturation, and values less than 1.0 decrease saturation. Increasing saturation makes colors more vivid, while decreasing it makes the image more grayscale.

hue

This parameter adjusts the hue of the image. The default value is 0.5, which means no change. Values can range from 0.0 to 1.0, where 0.0 and 1.0 represent a full cycle of hue rotation. Adjusting hue changes the overall color balance of the image.

gamma

This parameter controls the gamma correction of the image. A value of 1.0 means no change, values greater than 1.0 increase gamma, and values less than 1.0 decrease gamma. Gamma correction can help in adjusting the luminance of the image.

sharpness

This parameter adjusts the sharpness of the image. A value of 1.0 means no change, values greater than 1.0 increase sharpness, and values less than 1.0 decrease sharpness. Increasing sharpness makes the image appear more defined, while decreasing it makes the image softer.

red

This parameter controls the intensity of the red channel in the image. A value of 1.0 means no change, values greater than 1.0 increase the red intensity, and values less than 1.0 decrease it. Adjusting this can help in correcting or enhancing the red tones in the image.

green

This parameter controls the intensity of the green channel in the image. A value of 1.0 means no change, values greater than 1.0 increase the green intensity, and values less than 1.0 decrease it. Adjusting this can help in correcting or enhancing the green tones in the image.

blue

This parameter controls the intensity of the blue channel in the image. A value of 1.0 means no change, values greater than 1.0 increase the blue intensity, and values less than 1.0 decrease it. Adjusting this can help in correcting or enhancing the blue tones in the image.

ImageEffectsAdjustment Output Parameters:

images

The output is a batch of images with the specified adjustments applied. Each image will reflect the changes made to brightness, contrast, saturation, hue, gamma, sharpness, and individual color channels, resulting in a visually enhanced or corrected image.

ImageEffectsAdjustment Usage Tips:

• Experiment with small incremental changes to parameters like brightness, contrast, and saturation to achieve the desired effect without over-processing the image.
• Use the hue adjustment to create unique color effects or to correct color imbalances in your images.
• Adjust the gamma parameter to fine-tune the luminance and achieve a more natural look, especially in images with varying light conditions.
• Utilize the individual color channel adjustments (red, green, blue) to correct color casts or to emphasize specific colors in your image.

ImageEffectsAdjustment Common Errors and Solutions:

"Invalid image format"

• Explanation: This error occurs if the input images are not in the expected format or if they contain an unsupported number of channels.
• Solution: Ensure that the input images are in a standard format (e.g., RGB or RGBA) and that they are correctly pre-processed before being passed to the node.

"Parameter out of range"

• Explanation: This error occurs if one or more input parameters are set to values outside their acceptable ranges.
• Solution: Verify that all input parameters are within their specified ranges. For example, ensure that hue is between 0.0 and 1.0, and other parameters are set to reasonable values.

"Image processing failed"

• Explanation: This error can occur due to internal issues during the image processing steps, such as tensor operations failing.
• Solution: Check the input images for any anomalies and ensure that all dependencies and libraries required for image processing are correctly installed and up-to-date.
