A set of nodes for ComfyUI that can composite layer and mask to achieve Photoshop like functionality.
The LayerColor: Brightness & Contrast node is a feature within the ComfyUI project designed to adjust the visual aesthetics of an image by modifying its brightness, contrast, and saturation. This node is essential for refining image appearances and achieving the desired visual effects in ComfyUI workflows.
The LayerColor: Brightness & Contrast node takes an image as input and allows users to adjust the brightness, contrast, and saturation of the image using specified parameters. These adjustments help in enhancing image quality, aligning with specific style requirements, or preparing images for further processing or analysis.
Image: This input requires an image to be processed. Images are expected to be in a format that ComfyUI can handle and process.
Brightness: A float value ranging from 0.0 to 3.0. The default value is 1. Adjusting this parameter changes the brightness of the image. A value less than 1 will make the image darker, while a value greater than 1 will make it brighter.
Contrast: A float value ranging from 0.0 to 3.0. The default value is 1. This parameter modifies the contrast level of the image. A lower value decreases contrast (making the image appear flatter), whereas a higher value increases the contrast (making differences between light and dark areas more pronounced).
Saturation: A float value ranging from 0.0 to 3.0. The default value is 1. This parameter affects the intensity of colors in the image. A saturation value less than 1 will desaturate the image, while a value above 1 will enhance the color saturation.
The LayerColor: Brightness & Contrast node is ideal for workflows where image quality enhancement is crucial. It can be used in various scenarios, such as:
Pre-processing for Analysis: Adjust images before feeding them into other analysis nodes or machine learning models to ensure that the input data has the desired visual characteristics.
Style Enhancement: Modify the appearance of images to meet specific aesthetic requirements, which is useful in graphic design, digital art, and media production.
Image Correction: Improve underexposed images, increase visibility in low light scenarios, or adjust images for better print quality.
Parameter Range: The node provides a broad range of adjustable parameters for fine-tuning the image appearance. Users should experiment with these settings to achieve optimal results.
Mode Handling: The node can handle images with an alpha channel (RGBA mode) and properly manage the transparency during processing.
Batch Processing: Multiple images can be processed in a single run, making it suitable for batch processing tasks.
This node lacks explicit in-repo documentation, but further details and updates may be available on its GitHub repository.
By understanding and utilizing the LayerColor: Brightness & Contrast node effectively, users can significantly improve image processing tasks within the ComfyUI framework.
