ComfyUI Node: 🎨 AutoGradePro 2.0

🎨 AutoGradePro 2.0:

AutoGradePro is a sophisticated node designed to enhance your image processing workflow by providing advanced color grading capabilities. It is part of the ComfyUI custom nodes collection, specifically within the color tools category. The primary goal of AutoGradePro is to offer a comprehensive suite of color adjustment features that allow you to fine-tune the visual aesthetics of your images. This node is particularly beneficial for AI artists who wish to achieve precise control over the color dynamics of their artwork, enabling adjustments to shadows, midtones, highlights, and more. By leveraging AutoGradePro, you can enhance the vibrancy, contrast, and overall color balance of your images, resulting in visually striking and professionally graded outputs.

🎨 AutoGradePro 2.0 Input Parameters:

shadows

The shadows parameter allows you to adjust the darkness levels in the shadow areas of your image. This can help in bringing out details in darker regions without affecting the midtones and highlights. The range typically spans from 0.0 to 1.0, with a default value that maintains the original shadow intensity.

midtones

The midtones parameter is used to modify the brightness and color balance of the mid-range tones in your image. Adjusting this parameter can significantly impact the overall mood and depth of the image. It usually ranges from 0.0 to 1.0, with a default setting that preserves the natural midtone levels.

highlights

The highlights parameter controls the brightness and detail in the lighter areas of your image. By adjusting this, you can prevent overexposure and maintain detail in bright regions. The typical range is from 0.0 to 1.0, with a default value that keeps the highlights intact.

exposure

The exposure parameter affects the overall brightness of the image. Increasing exposure can make the image appear brighter, while decreasing it can darken the image. This parameter is crucial for correcting images that are too dark or too bright.

hue_shift

The hue_shift parameter allows you to change the overall color tone of the image by rotating the color wheel. This can be used creatively to alter the mood or style of the image. The range is usually from -180 to 180 degrees, with 0 as the default, indicating no shift.

saturation

The saturation parameter adjusts the intensity of the colors in your image. Increasing saturation makes colors more vivid, while decreasing it can lead to a more muted or grayscale appearance. The range is typically from 0.0 to 2.0, with 1.0 as the default for natural color intensity.

vibrance

The vibrance parameter is similar to saturation but focuses on boosting the intensity of less saturated colors, making it a more subtle adjustment. This helps in enhancing the image without oversaturating already vivid colors. The range is from 0.0 to 2.0, with a default of 1.0.

contrast

The contrast parameter modifies the difference between the darkest and lightest parts of the image. Increasing contrast can make the image appear more dynamic, while decreasing it can soften the image. The range is from 0.0 to 2.0, with 1.0 as the default.

pivot

The pivot parameter determines the midpoint around which contrast adjustments are made. This can be used to fine-tune how contrast affects different tonal ranges in the image. The range is typically from 0.0 to 1.0, with a default value that centers the contrast adjustment.

color_boost

The color_boost parameter enhances the overall color intensity, similar to saturation but with a focus on boosting all colors uniformly. This can be useful for making the image more vibrant. The range is from 0.0 to 2.0, with 1.0 as the default.

temperature

The temperature parameter adjusts the warmth or coolness of the image. Increasing the temperature adds a warm, yellowish tint, while decreasing it adds a cool, bluish tint. The range is typically from -100 to 100, with 0 as the default for a neutral temperature.

tint

The tint parameter allows you to adjust the green-magenta balance in the image. This can be used to correct color casts or achieve a specific artistic effect. The range is from -100 to 100, with 0 as the default for no tint adjustment.

levels_in_black

The levels_in_black parameter sets the input black level, determining which parts of the image are considered pure black. This can help in enhancing contrast and depth. The range is from 0.0 to 1.0, with a default value that maintains the original black level.

levels_in_white

The levels_in_white parameter sets the input white level, determining which parts of the image are considered pure white. Adjusting this can help in preventing overexposure. The range is from 0.0 to 1.0, with a default value that preserves the original white level.

levels_out_black

The levels_out_black parameter sets the output black level, allowing you to adjust the darkest parts of the image. This can be used to lift shadows and add detail. The range is from 0.0 to 1.0, with a default of 0.0 for pure black.

levels_out_white

The levels_out_white parameter sets the output white level, allowing you to adjust the brightest parts of the image. This can help in maintaining highlight details. The range is from 0.0 to 1.0, with a default of 1.0 for pure white.

🎨 AutoGradePro 2.0 Output Parameters:

graded_image

The graded_image is the final output of the AutoGradePro node, representing the image after all the specified color grading adjustments have been applied. This output is crucial as it reflects the enhanced visual quality and aesthetic improvements made through the node's parameters. The graded image can be used for further processing or as a final product for display or publication.

🎨 AutoGradePro 2.0 Usage Tips:

• Experiment with the hue_shift and temperature parameters to achieve unique color tones and moods in your images.
• Use the vibrance parameter to subtly enhance colors without oversaturating already vivid areas, maintaining a natural look.
• Adjust the contrast and pivot parameters together to fine-tune the dynamic range and depth of your image, ensuring that details are preserved in both shadows and highlights.

🎨 AutoGradePro 2.0 Common Errors and Solutions:

Image appears too dark or too bright

• Explanation: This issue may occur if the exposure or contrast parameters are set too high or too low.
• Solution: Adjust the exposure and contrast parameters to achieve a balanced brightness and contrast level.

Colors look unnatural or oversaturated

• Explanation: This can happen if the saturation or color_boost parameters are set too high.
• Solution: Reduce the saturation and color_boost values to achieve a more natural color balance.

Image has an unwanted color cast

• Explanation: An incorrect temperature or tint setting can introduce a color cast.
• Solution: Adjust the temperature and tint parameters to correct the color balance and remove any unwanted tints.
