Looks at the color information in each channel and selects the base or blend
color--whichever is lighter--as the result color. Pixels darker than the blend color
are replaced, and pixels lighter than the blend color do not change.
Hard Mix
The result of Hard Mix is either 0 or 255 for each channel. If the sum of upper
layer value and lower layer value is greater than 255, then it is 255, otherwise
the result will be 0. This mode is useful for color enhancement or special effects.
See the Example shown below:
Linear Dark/Light
Burns or dodges the colors by decreasing or increasing the brightness,
depending on the blend color. If the blend color (light source) is lighter than
50% gray, the image is lightened by increasing the brightness. If the blend color
is darker than 50% gray, the image is darkened by decreasing the brightness.
Multiply
Looks at the color information in each channel and multiplies the base color by
the blend color. The result color is always a darker color. Multiplying any color
with black produces black. Multiplying any color with white leaves the color
unchanged. When you're painting with a color other than black or white,
successive strokes with a painting tool produce progressively darker colors. The
effect is similar to drawing on the image with multiple magic markers.
