ComfyUI Node: ☼ Image Brightness Adjustment

Image Brightness Adjustment [Dream]:

The Image Brightness Adjustment [Dream] node is designed to help you fine-tune the brightness levels of your images with ease. This node is particularly useful for enhancing the visual appeal of your artwork by making it brighter or darker, depending on your creative needs. By adjusting the brightness, you can bring out hidden details, improve the overall mood, and make your images more visually striking. The node leverages a straightforward method to modify the brightness, ensuring that the changes are applied uniformly across the entire image. This makes it an essential tool for AI artists looking to perfect their digital creations without delving into complex image processing techniques.

Image Brightness Adjustment [Dream] Input Parameters:

image

This parameter accepts the image you want to adjust. It should be in a format recognized by the node, typically an IMAGE type. The image serves as the base on which the brightness adjustments will be applied.

factor

The factor parameter controls the level of brightness adjustment. It is a floating-point value with a default of 1.0, a minimum of 0.0, and no specified maximum. A factor of 1.0 means no change in brightness, values greater than 1.0 will increase the brightness, and values less than 1.0 will decrease it. Adjusting this parameter allows you to fine-tune the brightness to achieve the desired visual effect.

Image Brightness Adjustment [Dream] Output Parameters:

image

The output is the adjusted image, returned as an IMAGE type. This image reflects the changes made based on the brightness factor you specified. The output image will have the same dimensions and format as the input image but with the brightness levels modified according to your settings.

Image Brightness Adjustment [Dream] Usage Tips:

• Experiment with the factor parameter to find the perfect brightness level for your image. Start with small increments to see how slight changes affect the overall appearance.
• Use this node in combination with other color adjustment nodes, such as contrast or color shift, to achieve a more balanced and visually appealing result.
• If your image appears too dark or too bright after adjustment, try using a factor closer to 1.0 to make more subtle changes.
