ComfyUI Node: 🎨 CR Vignette Filter

🎨 CR Vignette Filter:

The CR Vignette Filter is a powerful node designed to apply a vignette effect to your images, enhancing their visual appeal by subtly darkening the edges and drawing attention to the center. This effect is commonly used in photography and graphic design to create a focal point and add a professional touch to images. The vignette filter can be customized in various ways, allowing you to adjust the feather amount, shape, and position of the vignette, as well as whether to reverse the effect. This flexibility makes it a versatile tool for AI artists looking to add depth and focus to their creations.

🎨 CR Vignette Filter Input Parameters:

image

The image parameter is the primary input for the node, representing the image to which the vignette effect will be applied. This parameter is essential as it serves as the base on which all other adjustments will be made.

feather_amount

The feather_amount parameter controls the softness of the vignette edges. A higher value results in a smoother transition between the vignette and the image, creating a more subtle effect. Conversely, a lower value produces a sharper, more defined vignette. This parameter allows for fine-tuning the visual impact of the vignette.

reverse

The reverse parameter is a boolean option that, when enabled, inverts the vignette effect, making the center of the image darker and the edges lighter. This can be useful for creating unique visual effects or highlighting the periphery of the image instead of the center.

vignette_shape

The vignette_shape parameter determines the shape of the vignette applied to the image. Common shapes include "circle" and "ellipse," but other shapes may be available depending on the implementation. This parameter allows for creative flexibility in how the vignette effect is applied.

x_offset

The x_offset parameter adjusts the horizontal position of the vignette effect. By changing this value, you can move the vignette center to the left or right, allowing for precise control over the focal point of the image.

y_offset

The y_offset parameter adjusts the vertical position of the vignette effect. Similar to the x_offset, this value lets you move the vignette center up or down, providing additional control over the image's focus area.

zoom

The zoom parameter controls the scale of the vignette effect. A higher zoom value enlarges the vignette, covering more of the image, while a lower value reduces its size. This parameter helps in adjusting the intensity and coverage of the vignette effect.

🎨 CR Vignette Filter Output Parameters:

output_image

The output_image parameter is the resulting image after the vignette effect has been applied. This image will have the specified vignette adjustments, enhancing its visual appeal and drawing attention to the desired focal point.

🎨 CR Vignette Filter Usage Tips:

• Experiment with different feather_amount values to achieve the desired softness of the vignette edges.
• Use the reverse parameter to create unique lighting effects by inverting the vignette.
• Adjust the x_offset and y_offset parameters to precisely position the vignette effect and highlight specific areas of your image.
• Try different vignette_shape options to see which best complements your image's composition.

🎨 CR Vignette Filter Common Errors and Solutions:

Invalid image input

• Explanation: The image parameter is not correctly provided or is in an unsupported format.
• Solution: Ensure that the input image is correctly loaded and in a supported format such as JPEG or PNG.

Feather amount out of range

• Explanation: The feather_amount parameter is set to a value outside the acceptable range.
• Solution: Adjust the feather_amount to a value within the supported range, typically between 0 and 100.

Unsupported vignette shape

• Explanation: The vignette_shape parameter is set to an unsupported shape.
• Solution: Choose a supported shape such as "circle" or "ellipse" for the vignette_shape parameter.

Invalid zoom value

• Explanation: The zoom parameter is set to a value that is not supported.
• Solution: Ensure the zoom value is within the acceptable range, typically greater than 0.
