If you want to make a photo black and white in Photoshop, there are a few different ways to do it. One way is to use the Black & White adjustment layer. To do this, first select the photo you want to black and white, and then click on the Black & White adjustment layer icon at the bottom of the Layers panel. To adjust the black and white levels, simply drag the slider left or right. You can also use the eyedropper tool to sample different parts of the image and adjust the levels accordingly. If you want to make a completely black and white image, simply drag the slider all the way to the left. ..
