ComfyUI Node: ImageEffectsLensOpticAxis

ImageEffectsLensOpticAxis:

The ImageEffectsLensOpticAxis node is designed to simulate the optical effects of a lens on an image, providing a realistic and artistic touch to your visuals. This node allows you to manipulate various aspects of the lens effect, such as shape, edge, curvature, and zoom, to create unique and dynamic images. By adjusting brightness and saturation, you can further enhance the visual impact, making it a versatile tool for AI artists looking to add depth and realism to their creations. The primary goal of this node is to offer a flexible and intuitive way to apply lens effects, enabling you to achieve professional-quality results with ease.

ImageEffectsLensOpticAxis Input Parameters:

images

This parameter represents the input image or batch of images that you want to apply the lens effect to. It is essential as it serves as the base upon which all other effects are applied.

lens_shape

This parameter defines the shape of the lens effect. Different shapes can create various visual impacts, allowing you to customize the look and feel of the lens effect to match your artistic vision.

lens_edge

This parameter determines the edge style of the lens effect. Options include "around" for a circular edge and "symmetric" for a symmetrical edge. The choice of edge style can significantly influence the overall appearance of the effect.

lens_curvy

This parameter controls the curvature of the lens effect. Higher values result in more pronounced curvature, which can create a more dramatic and immersive effect. The range of values typically varies from 0 to 1, with 0 being no curvature and 1 being maximum curvature.

lens_zoom

This parameter adjusts the zoom level of the lens effect. Increasing the zoom level can make the effect more intense and focused, while decreasing it can create a more subtle and diffuse effect. The default value is usually set to 1, with higher values increasing the zoom.

brightness

This parameter modifies the brightness of the image within the lens effect area. Adjusting the brightness can help highlight specific areas and create a more striking visual contrast. The range of values typically varies from 0 to 2, with 1 being the default value.

saturation

This parameter changes the saturation of the image within the lens effect area. Higher saturation values can make colors more vibrant, while lower values can create a more muted and subdued effect. The range of values typically varies from 0 to 2, with 1 being the default value.

ImageEffectsLensOpticAxis Output Parameters:

result

This output parameter provides the final image with the applied lens effect. It combines the original image with the modified areas based on the input parameters, resulting in a visually enhanced image.

mask

This output parameter provides the mask used to apply the lens effect. The mask indicates the areas of the image that were affected by the lens effect, which can be useful for further processing or analysis.

ImageEffectsLensOpticAxis Usage Tips:

• Experiment with different lens_shape and lens_edge combinations to achieve unique visual effects.
• Use the lens_curvy parameter to create more dynamic and immersive lens effects.
• Adjust the brightness and saturation parameters to enhance specific areas of your image and create a more striking visual contrast.
• Start with the default lens_zoom value and gradually increase or decrease it to find the optimal zoom level for your image.

ImageEffectsLensOpticAxis Common Errors and Solutions:

ValueError: Not existing lens_edge parameter.

• Explanation: This error occurs when an invalid value is provided for the lens_edge parameter.
• Solution: Ensure that the lens_edge parameter is set to either "around" or "symmetric".

RuntimeError: shape '[x, y, z, w]' is invalid for input of size n

• Explanation: This error may occur if the dimensions of the input image do not match the expected dimensions.
• Solution: Verify that the input image dimensions are correct and compatible with the node's requirements.

TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'

• Explanation: This error can occur if one of the input parameters is not properly initialized or is set to None.
• Solution: Ensure that all input parameters are correctly set and not None before executing the node.
