Five ways to turn color photos into black and white with PS?

Using photoshop software, there are many ways to turn color photos into black. Let me briefly introduce five methods to you.

In the first way, we can adjust the picture to grayscale mode. We open a picture and then adjust the color mode of the picture to grayscale.

The second method is to change the color picture into black and white by adjusting the hue/saturation. We just need to adjust the saturation value to the minimum.

The third method is to execute the image-adjust-black and white command, or you can adjust the color picture to black and white.

The fourth method is to decolorize the color picture.

The fifth method is to add a black and white adjustment layer to the picture. This method has the same principle as performing image-adjustment-black and white.
