There are a few things you need to know if you want to do black and white on Photoshop. First, make sure that your image is in RGB color space. Second, make sure that the layer is selected. Finally, use the following commands to create the black and white effect:
- Choose Image > Mode > Black & White.
- In the Black & White dialog box, choose a black point (the darkest point), and then set a white point (the lightest point).
- Click OK to create the effect.
