添加杂色

“添加杂色”滤镜将随机像素应用于图像,从而模拟在高速胶片上拍摄图片的效果。该滤镜还可用于减少羽化选区或渐变填充中的条纹,为过多修饰的区域提供更真实的外观,或创建纹理图层。可以设置杂色的数量、杂色分布的类型以及颜色模式。“平均”选项创建稀薄分布的外观,“高斯”创建散布分布的外观。“单色”使用图像的现有色调应用滤镜,而不会更改颜色。

去斑

“去斑”滤镜检测图层的边缘(发生显著颜色变化的区域)并模糊除那些边缘外的所有选区。该模糊操作会移去杂色,同时保留细节。可以使用该滤镜去除通常出现在扫描杂志或其他打印材料中的条纹或可视杂色。

蒙尘与划痕

“蒙尘与划痕”滤镜通过更改不同的像素减少可视杂色。

中间值

“中间值”滤镜通过混合选区内像素的亮度减少图层中的杂色。此滤镜搜索亮度相近的像素,从而扔掉与相邻像素差异较大的像素,并用搜索到的像素的中间亮度值替换中心像素。该滤镜对于消除或减少图像上动感的外观或可能出现在扫描图像中不理想的图案非常有用。

减少杂色

“减少杂色”滤镜减少发光的杂色和颜色杂色,如由于在光线不充足的条件下拍摄照片而产生的杂色。选择“移去 JPEG 不自然感”选项可去除用较低的 JPEG 品质设置存储图像而引起的斑驳的伪像和光晕。

在这张用移动电话拍摄的照片中,男孩脸部有杂色(左图)。“减少杂色”滤镜平滑掉分离的像素(右图)。
