💡 Lens Flare:

The LensFlareNode is designed to enhance your images by adding realistic lens flare effects, which are optical phenomena that occur when a bright light source interacts with a camera lens. This node allows you to simulate various types of lens flares, such as classic, anamorphic, starburst, and hexagonal, each offering a unique visual style. By incorporating these effects, you can add depth and dynamism to your images, making them more visually appealing and professional. The node is particularly useful for artists looking to create dramatic lighting effects or to simulate the look of cinematic photography. It provides a range of customizable parameters, enabling you to control the intensity, size, position, and color temperature of the flare, allowing for precise adjustments to match your creative vision.

💡 Lens Flare Input Parameters:

image

This parameter represents the input image to which the lens flare effect will be applied. It is essential as it serves as the base layer for the effect.

flare_type

This parameter determines the style of the lens flare effect. Options include "classic", "anamorphic", "starburst", and "hexagonal", with "classic" as the default. Each type offers a distinct visual appearance, allowing you to choose the one that best fits your artistic needs.

intensity

This parameter controls the brightness of the lens flare effect. It ranges from 0.0 to 2.0, with a default value of 0.5. A higher intensity will make the flare more prominent, while a lower intensity will result in a subtler effect.

size

This parameter adjusts the overall size of the lens flare effect. It ranges from 0.1 to 1.0, with a default value of 0.3. Increasing the size will make the flare cover a larger area of the image, while decreasing it will confine the effect to a smaller region.

position_x

This optional parameter sets the horizontal position of the lens flare on the image, ranging from 0.0 to 1.0, with a default value of 0.7. It allows you to place the flare at a specific point along the x-axis.

position_y

This optional parameter sets the vertical position of the lens flare on the image, ranging from 0.0 to 1.0, with a default value of 0.3. It allows you to place the flare at a specific point along the y-axis.

color_temp

This optional parameter defines the color temperature of the lens flare, measured in Kelvin. It ranges from 2000.0 to 10000.0, with a default value of 5500.0. Adjusting this parameter can simulate different lighting conditions, from warm to cool tones.

rays

This optional parameter is specific to the "starburst" flare type and determines the number of rays emanating from the flare. It ranges from 4 to 12, with a default value of 6. More rays will create a more complex starburst pattern.

💡 Lens Flare Output Parameters:

IMAGE

The output is an image with the applied lens flare effect. This enhanced image can be used in various creative projects, providing a more dynamic and visually interesting result. The output maintains the original image's dimensions and format, ensuring compatibility with subsequent processing steps.

💡 Lens Flare Usage Tips:

• Experiment with different flare_type options to find the style that best complements your image. Each type offers a unique aesthetic, so try them all to see which one fits your creative vision.
• Use the intensity and size parameters to fine-tune the prominence and coverage of the lens flare. A subtle effect can add realism without overpowering the image, while a more intense flare can create a dramatic focal point.

💡 Lens Flare Common Errors and Solutions:

Image shape mismatch

• Explanation: This error occurs when the input image does not have the expected shape or dimensions.
• Solution: Ensure that the input image is correctly formatted and has the appropriate dimensions for processing.

Invalid flare type

• Explanation: This error arises when an unsupported flare type is specified.
• Solution: Check that the flare_type parameter is set to one of the supported options: "classic", "anamorphic", "starburst", or "hexagonal".

Out of range parameter value

• Explanation: This error happens when a parameter value is set outside its allowed range.
• Solution: Verify that all parameter values are within their specified ranges and adjust them accordingly.
