ComfyUI Node: 🎨 PS Curve Preset

🎨 PS Curve Preset:

The CurvePresetNode is a versatile tool designed to apply predefined curve adjustments to images, enhancing their visual appeal by altering contrast, brightness, and color balance. This node is particularly beneficial for AI artists looking to quickly apply complex color grading and stylistic effects without manually adjusting each parameter. By selecting from a wide array of preset styles, users can effortlessly transform their images to match specific artistic themes or moods, such as vintage film, modern minimalism, or high contrast. The node's primary function is to retrieve and apply these preset curves, streamlining the image editing process and allowing for consistent and repeatable results across different projects.

🎨 PS Curve Preset Input Parameters:

preset_style

The preset_style parameter allows you to choose from a variety of predefined curve styles that dictate how the image will be adjusted. These styles range from basic adjustments like Linear (无调整) to more complex and thematic options such as 电影蓝橙 (Cinematic Blue-Orange) or 复古胶片 (Vintage Film). Each style represents a unique set of curve points that modify the image's tonal range and color balance. The default value is Linear (无调整), which applies no adjustment, maintaining the original image appearance. Selecting a different style will apply the corresponding curve, altering the image's visual characteristics to match the chosen theme.

unique_id

The unique_id parameter is a hidden input that serves as an identifier for the node's instance. It is used internally to track changes and ensure that the correct preset curve is applied. This parameter does not require user input and is automatically managed by the system.

🎨 PS Curve Preset Output Parameters:

curve_points

The curve_points output parameter provides the set of curve points corresponding to the selected preset_style. These points define the transformation applied to the image's tonal range, effectively altering its contrast, brightness, and color balance. The output is a string representation of the curve points, which can be used to understand the specific adjustments made to the image. This output is crucial for users who wish to analyze or further modify the applied curve settings.

🎨 PS Curve Preset Usage Tips:

• Experiment with different preset_style options to quickly find the best fit for your image's desired mood or theme.
• Use the Linear (无调整) style as a baseline to compare the effects of other presets and better understand their impact on your image.
• Combine this node with other adjustment nodes to create more complex and customized image effects.

🎨 PS Curve Preset Common Errors and Solutions:

🎨 PS Curve Preset error: <error_message>

• Explanation: This error occurs when there is an issue retrieving the preset curve points, possibly due to an invalid preset_style selection or an internal processing error.
• Solution: Ensure that the preset_style is correctly selected from the available options. If the error persists, try resetting the node or reloading the project to resolve any temporary issues.
