ComfyUI Node: 🎛️ Pro Color Grading

🎛️ Pro Color Grading:

The ProColorGrading node is a powerful tool designed to enhance and manipulate the color properties of an image, providing you with a comprehensive suite of color grading capabilities. This node allows you to adjust various aspects of an image's color profile, such as shadows, midtones, highlights, and more, to achieve the desired visual effect. By offering a range of parameters, ProColorGrading enables you to fine-tune the exposure, hue, saturation, and contrast, among other attributes, to create visually appealing and professionally graded images. This node is particularly beneficial for AI artists looking to add depth, vibrancy, and mood to their artwork, making it an essential component in the digital art creation process.

🎛️ Pro Color Grading Input Parameters:

image

The image parameter is the input image that you want to apply color grading to. It serves as the base upon which all other adjustments will be made.

shadows

The shadows parameter allows you to adjust the darkness of the shadow areas in the image. It ranges from -1.0 to 1.0, with a default value of 0.0. Increasing this value will lighten the shadows, while decreasing it will darken them.

midtones

The midtones parameter controls the brightness of the midtone areas in the image. It also ranges from -1.0 to 1.0, with a default value of 0.0. Adjusting this parameter can help balance the overall exposure of the image.

highlights

The highlights parameter is used to adjust the brightness of the highlight areas. It ranges from -1.0 to 1.0, with a default value of 0.0. Increasing this value will brighten the highlights, while decreasing it will darken them.

exposure

The exposure parameter affects the overall brightness of the image. It ranges from -2.0 to 2.0, with a default value of 0.0. This parameter is useful for correcting underexposed or overexposed images.

hue_shift

The hue_shift parameter allows you to change the overall hue of the image. It ranges from -180.0 to 180.0, with a default value of 0.0. This can be used to create artistic effects or correct color casts.

saturation

The saturation parameter controls the intensity of the colors in the image. It ranges from 0.0 to 3.0, with a default value of 1.0. Increasing saturation will make colors more vivid, while decreasing it will make them more muted.

vibrance

The vibrance parameter enhances the intensity of less saturated colors more than the already saturated ones. It ranges from 0.0 to 3.0, with a default value of 0.0. This helps in achieving a balanced color enhancement.

contrast

The contrast parameter adjusts the difference between the darkest and lightest parts of the image. It ranges from 0.0 to 3.0, with a default value of 1.0. Higher contrast can make an image appear more dynamic.

pivot

The pivot parameter determines the midpoint around which contrast adjustments are made. It ranges from 0.0 to 1.0, with a default value of 0.5. This can be used to control which tones are affected by contrast changes.

color_boost

The color_boost parameter increases the overall color intensity in the image. It ranges from 0.0 to 3.0, with a default value of 1.0. This is useful for making colors pop without affecting brightness.

temperature

The temperature parameter adjusts the color temperature of the image, making it appear warmer or cooler. It ranges from -1.0 to 1.0, with a default value of 0.0. This can be used to correct white balance or create mood.

tint

The tint parameter allows you to adjust the green-magenta balance in the image. It ranges from -1.0 to 1.0, with a default value of 0.0. This is useful for correcting color casts.

levels_in_black

The levels_in_black parameter sets the black point of the input levels. It ranges from 0.0 to 1.0, with a default value of 0.0. This can be used to deepen shadows and increase contrast.

levels_in_white

The levels_in_white parameter sets the white point of the input levels. It ranges from 0.0 to 1.0, with a default value of 1.0. This can be used to brighten highlights and increase contrast.

levels_out_black

The levels_out_black parameter sets the black point of the output levels. It ranges from 0.0 to 1.0, with a default value of 0.0. This can be used to adjust the darkest tones in the image.

levels_out_white

The levels_out_white parameter sets the white point of the output levels. It ranges from 0.0 to 1.0, with a default value of 1.0. This can be used to adjust the brightest tones in the image.

🎛️ Pro Color Grading Output Parameters:

image

The output image is the result of applying the color grading adjustments to the input image. It reflects all the changes made through the input parameters, providing a visually enhanced version of the original image.

🎛️ Pro Color Grading Usage Tips:

• Experiment with the hue_shift and saturation parameters to create unique color effects that can add a creative touch to your artwork.
• Use the contrast and pivot parameters together to fine-tune the dynamic range of your image, ensuring that important details are neither lost in shadows nor blown out in highlights.
• Adjust the temperature and tint parameters to correct any unwanted color casts and achieve a natural-looking white balance.

🎛️ Pro Color Grading Common Errors and Solutions:

Image not displaying correctly

• Explanation: This may occur if the input image format is not supported or if there is an issue with the image file itself.
• Solution: Ensure that the input image is in a compatible format and that the file is not corrupted. Try reloading the image or using a different file format.

Unexpected color shifts

• Explanation: This can happen if the hue_shift, temperature, or tint parameters are set to extreme values.
• Solution: Reset these parameters to their default values and gradually adjust them to achieve the desired effect without causing unnatural color shifts.
