Better Black and White Images

Don’t just desaturate images (by going to Image > adjustment > desaturate) to make black and white photos. Instead, make a Black and White adjustment layer (In the Layers panel) and use the six color sliders, that control one of the six primary colors in the image, to adjust the brightness of each color.

Even better, click on the “click and drag” icon then click on any area of the image that you want to make darker or lighter and drag—left to make them lighter, right to make them darker.
