Step 3: Contrast and Brightness
1. Below the Layers tab, click on the box for "New Fill Layer" and choose "Black and White." This will create a black and white copy of the image in a layer above the original.
2. Select this layer and choose blending mode, "Multiply." This blending mode deletes parts of the image according to their color. For example, a 100% white pixel is deleted completely, and a 100% black pixel is left along. A gray pixel halfway between black and white will be made 50% opaque. This results in a unique effect that dramatically changes the images colors and mood.
3. Adjust the color sliders according to your image and taste.
