ComfyUI Node: Image Filter Adjustments

Image Filter Adjustments:

The Image Filter Adjustments node is designed to provide a comprehensive suite of image enhancement tools, allowing you to fine-tune various aspects of your images. This node is particularly useful for adjusting brightness, contrast, saturation, sharpness, and applying various blur effects. By leveraging these adjustments, you can significantly improve the visual quality of your images, making them more vibrant, detailed, or stylistically unique. Whether you are looking to enhance the overall appearance of an image or prepare it for further processing, this node offers a versatile and user-friendly solution.

Image Filter Adjustments Input Parameters:

image

This parameter accepts the image you wish to adjust. The image should be in a compatible format that the node can process.

brightness

This parameter controls the brightness level of the image. Increasing the value makes the image brighter, while decreasing it makes the image darker. The value range is from -1.0 to 1.0, with a default value of 0.0.

contrast

This parameter adjusts the contrast of the image. Higher values increase the contrast, making the darks darker and the lights lighter, while lower values decrease the contrast. The value range is from 0.0 to 2.0, with a default value of 1.0.

saturation

This parameter modifies the saturation of the image, affecting the intensity of the colors. Higher values make the colors more vivid, while lower values make them more muted. The value range is from 0.0 to 2.0, with a default value of 1.0.

sharpness

This parameter enhances the sharpness of the image, making the details more pronounced. Higher values increase sharpness, while lower values reduce it. The value range is from 0.0 to 2.0, with a default value of 1.0.

blur

This parameter applies a blur effect to the image. The higher the value, the more pronounced the blur. The value range is from 0 to 10, with a default value of 0.

gaussian_blur

This parameter applies a Gaussian blur effect, which is a type of blur that uses a Gaussian function. The higher the value, the more pronounced the blur. The value range is from 0 to 10, with a default value of 0.

edge_enhance

This parameter enhances the edges within the image, making them more defined. The value range is from 0.0 to 2.0, with a default value of 1.0.

detail_enhance

This parameter enhances the finer details of the image, making textures and small features more visible. The value range is from 0.0 to 2.0, with a default value of 1.0.

Image Filter Adjustments Output Parameters:

IMAGE

The output is the adjusted image, which reflects all the modifications made based on the input parameters. This image can be used for further processing or as a final output for your project.

Image Filter Adjustments Usage Tips:

• Experiment with small increments when adjusting brightness and contrast to avoid overexposure or underexposure.
• Use the saturation parameter to make your images more vibrant, but be cautious of oversaturation, which can make the image look unnatural.
• Apply sharpness adjustments to enhance details, especially in images with fine textures or intricate patterns.
• Utilize the blur and Gaussian blur parameters to create a soft focus effect or to reduce noise in the image.
• Combine edge enhancement and detail enhancement to make the image more striking and visually appealing.

Image Filter Adjustments Common Errors and Solutions:

Image not displaying correctly after adjustments

• Explanation: This could be due to extreme values in the input parameters.
• Solution: Ensure that the input parameters are within the recommended ranges and adjust them incrementally.

Image appears too dark or too bright

• Explanation: The brightness or contrast values might be set too high or too low.
• Solution: Reset the brightness and contrast parameters to their default values and adjust them gradually.

Colors look unnatural

• Explanation: The saturation parameter might be set too high.
• Solution: Reduce the saturation value to a more moderate level and check the image again.

Image looks blurry or lacks detail

• Explanation: The blur or Gaussian blur parameters might be set too high, or the sharpness parameter might be too low.
• Solution: Decrease the blur values and increase the sharpness parameter to enhance image clarity.
