In this tutorial, you will learn how to convert photos to black and white in Photoshop. We will use two techniques that will give you a lot of control and allow you to work non-destructively.
The first technique we will work with the Black and White Adjustment layer (introduced in Photoshop CS3). The Black and White Adjustment Layer allows you to control how dark or how bright specific colors will display after the black and white conversion has been made.
The second technique is very similar, but it instead uses the Camera RAW filter’s HSL sliders. They work the same way as the Black and White adjustment Layer but it offers two additional sliders. The “Oranges” slider, and the “Purple” slider.
