What is the difference between black and white and decoloration in PS?

1, simple color removal and complex black and white.

2. Decolorization can not achieve the effect of black and white, but black and white can achieve the effect of decolorization.

3. It cannot be adjusted after the color removal operation, and the black and white adjustment layer can be adjusted after the operation.

The specific differences are as follows:

Difference: Decolorization is much simpler. Decolorization only changes the original picture into a gray image. Other colors are only gray, and there is little difference between light and shade.

The effect of black and white is much greater than that of color removal. It can be said that color removal is ok, and black and white is also completely ok. Black and white means that you can edit the degree to which various colors become black and white. For example, there are red, green, blue, cyan and magenta in the picture. After changing to black and white, we can edit the image of a certain color in black and white separately. For example, if I want to change the red area in the image to black and white, and then the red area becomes dark, we can adjust the slider of the red area.

Extended data:

Smart objects, adjustment layers, masks and other tools can often be used in ps. The advantage of these tools is that when you edit an image incorrectly, you can adjust it at any time to avoid damaging the original image or causing efficiency problems due to the wrong P-picture. 、
