色调校正与特效
让画像变亮、提高对比度、添加发光效果让画面更帅气，这对于设计师和画师来说是熟悉的工序。
在图像生成中，有时也会使用这些功能作为“预处理”，将图像调整为 AI 易于处理的状态。
虽然有很多关于图像处理的自定义节点，也能进行更高级的处理，但老实说，在很多场合下，使用习惯的绘图工具会觉得更轻松。
没有必要全部都在 ComfyUI 中完成。
基本加工
Invert image 节点
生成反转了 RGB 值的底片图像。

稍微有点小众，但在进行 image2image 时，有一种技巧是特意添加噪点，从而在低 denoise 设置下增加细节。
cf. 向像素图像添加噪点，在低 denoise 的 image2image 中增加细节
形态学转换 (Morphology)
可能不太熟悉这个词，主要是针对黑白蒙版图像进行处理。 可以进行“加粗线条（膨胀）”、“去除噪点（收缩）”等处理。

专业的色调校正（自定义节点）
像 Photoshop 那样，添加更实用的图像编辑功能的自定义节点多如繁星。 其中，我推荐一个涵盖了基本功能，并且简单易用的。
ComfyUI-Image-Effects
色相、饱和度、亮度的调整（HSV 调整），或者类似色调曲线的调整，以及各种滤镜等，只要是人类想要调整的功能，大多都包含在内。 详细的功能列表请查看仓库的文档。
