ComfyUI Node: ImageBlend

ImageBlend:

The ImageBlend node is designed to seamlessly combine two images using various blending modes, allowing you to create visually appealing and complex compositions. This node is particularly useful for post-processing tasks where you want to merge different visual elements or apply specific blending effects to enhance the final image. By leveraging different blend modes such as multiply, screen, overlay, soft light, and difference, you can achieve a wide range of artistic effects. The blend factor parameter allows you to control the intensity of the blending, giving you fine-grained control over the final output. This node is essential for AI artists looking to add depth, texture, and unique visual styles to their images.

ImageBlend Input Parameters:

image1

This parameter represents the first input image that will be blended with the second image. It is a required parameter and should be provided in the form of a tensor. The first image serves as the base layer in the blending process.

image2

This parameter represents the second input image that will be blended with the first image. It is also a required parameter and should be provided in the form of a tensor. The second image serves as the top layer in the blending process.

blend_factor

The blend factor controls the intensity of the blending between the two images. It is a floating-point value that ranges from 0.0 to 1.0, with a default value of 0.5. A blend factor of 0.0 means only the first image is visible, while a blend factor of 1.0 means only the second image is visible. Intermediate values create a mix of both images.

blend_mode

The blend mode determines the mathematical operation used to combine the two images. Available options are "normal", "multiply", "screen", "overlay", "soft_light", and "difference". Each mode produces a different visual effect, allowing you to choose the one that best suits your artistic needs.

ImageBlend Output Parameters:

IMAGE

The output parameter is the blended image resulting from the combination of the two input images using the specified blend mode and blend factor. This image is returned as a tensor and represents the final composition that can be used for further processing or final output.

ImageBlend Usage Tips:

• Experiment with different blend modes to achieve various artistic effects. For example, use "multiply" to darken the image or "screen" to lighten it.
• Adjust the blend factor to fine-tune the intensity of the blending. A lower blend factor will make the first image more prominent, while a higher blend factor will emphasize the second image.
• Ensure that both input images have the same dimensions for optimal results. If they do not, consider resizing or cropping them before blending.

ImageBlend Common Errors and Solutions:

Unsupported blend mode: <mode>

• Explanation: This error occurs when an invalid blend mode is specified.
• Solution: Ensure that the blend mode is one of the supported options: "normal", "multiply", "screen", "overlay", "soft_light", or "difference".

Shape mismatch between input images

• Explanation: This error occurs when the two input images have different dimensions.
• Solution: Resize or crop the images to ensure they have the same dimensions before blending.

Invalid blend factor value

• Explanation: This error occurs when the blend factor is outside the range of 0.0 to 1.0.
• Solution: Ensure that the blend factor is a floating-point value between 0.0 and 1.0.
