The Blend Modes specified in the options bar control how pixels in two separate layers interact with and effect each other. It’s helpful to think in terms of the following colors when visualizing a blending mode’s effect:
- The base color is the original color in the bottom layer.
- The blend color is the color being applied by the upper layer.
- The result color is the color resulting from the blend.
I decided to use two different examples for this demonstration. The first gives you an example of a simple photo with a complex and colorful texture while the second gives you a complex photo with a simple texture. This should give you a better visual of exactly what each mode does.
Remember that to get better results you can also adjust the opacity of the upper layer.
