ComfyUI Node: FL Retro Effect

FL Retro Effect:

The FL_RetroEffect node is designed to apply a nostalgic retro effect to your images, reminiscent of old television screens and vintage photographs. This node enhances your images by adding a combination of color offset, scanlines, vignette, and noise, giving them a unique and artistic retro look. The primary goal of this node is to transform modern digital images into visually appealing retro-style artworks, making it a valuable tool for AI artists looking to add a touch of vintage charm to their creations.

FL Retro Effect Input Parameters:

images

This is the primary input parameter where you provide the images you want to apply the retro effect to. The node processes each image individually and applies the specified retro effects.

color_offset

This parameter controls the color offset effect, which adjusts the brightness of the red and blue channels to create a color shift. The value ranges from 0.0 to 1.0, with a default value of 0.2. Increasing this value will enhance the color shift effect, giving your images a more pronounced retro look.

scanline_strength

This parameter determines the strength of the scanline effect, which simulates the horizontal lines seen on old CRT screens. The value ranges from 0.0 to 1.0, with a default value of 0.5. Higher values will make the scanlines more visible, adding to the vintage feel of the image.

vignette_strength

This parameter controls the strength of the vignette effect, which darkens the edges of the image to draw attention to the center. The value ranges from 0.0 to 1.0, with a default value of 0.7. Increasing this value will make the vignette effect more pronounced, enhancing the retro aesthetic.

noise_strength

This parameter adjusts the strength of the noise effect, which adds random visual noise to the image, mimicking the grainy texture of old photographs. The value ranges from 0.0 to 1.0, with a default value of 0.3. Higher values will increase the amount of noise, giving the image a more aged appearance.

FL Retro Effect Output Parameters:

IMAGE

The output of this node is the processed image with the applied retro effects. The resulting image will have the combined effects of color offset, scanlines, vignette, and noise, giving it a distinct retro look. This output can be used directly in your projects or further processed with other nodes.

FL Retro Effect Usage Tips:

• Experiment with different combinations of color_offset, scanline_strength, vignette_strength, and noise_strength to achieve the desired retro effect.
• Use lower values for a subtle retro look and higher values for a more dramatic vintage appearance.
• Combine this node with other image processing nodes to create unique and complex visual effects.

FL Retro Effect Common Errors and Solutions:

"Input image is not valid"

• Explanation: This error occurs when the provided input image is not in a valid format or is corrupted.
• Solution: Ensure that the input image is a valid image file and is not corrupted. Try using a different image to see if the issue persists.

"Parameter value out of range"

• Explanation: This error occurs when one of the input parameters is set to a value outside its allowed range.
• Solution: Check the values of color_offset, scanline_strength, vignette_strength, and noise_strength to ensure they are within the specified ranges. Adjust the values accordingly and try again.
