怎样操作才可以不损伤原图像质量?怎样才不算破坏性编辑?这个问题其实是一种在保护或不损失原始图像质量的情况下,做一些能够随时还原的操作(PS默认情况下历史记录调板只提供20步还原操作,这些步骤很容易用完,而且破坏图像)。非破坏性编辑方法之一就是使用图层蒙版功能,这样我们就永远不会实际擦除像素,而只是隐藏或显示它们。 How to do it without damaging the quality of the original image? What is not destructive editing? This problem is actually an operation that can be restored at any time with or without loss of the original image quality (PS by default history The palette only provides 20-step restore operation, these steps are easy to use, but also damage the image). One of the non-destructive editing methods is the use of layer masking, so that we will never actually erase pixels, but just hide or show them.
