Operation Manual

Changing the transparency of objects | 367
Merge mode Description
Hue Uses the hue of the transparency color, as well as the saturation
and lightness of the base color. If you are adding color to a
grayscale image, there will be no change because the colors are
desaturated.
Saturation Uses the lightness and hue of the base color and the saturation of
the transparency color
Lightness Uses the hue and saturation of the base color and the lightness of
the transparency color
Invert Uses the transparency color’s complementary color. If a
transparency color value is 127, there will be no change because
the color value falls in the center of the color wheel.
Logical AND Converts the transparency and base colors to binary values, and
then applies the Boolean algebraic formula AND to these values
Logical OR Converts the transparency and base colors to binary values, and
then applies the Boolean algebraic formula OR to these values
Logical XOR Converts the transparency and base colors to binary values, and
then applies the Boolean algebraic formula XOR to these values
Behind Applies the source color to those areas of the image that are
transparent. The effect is similar to looking through the clear, silver-
free areas on a 35-mm negative.
Screen Inverts the source and base color values, multiplies them, and then
inverts the result. The result color is always lighter than the base
color.
Overlay Multiplies or screens the source color according to the value of the
base color
Soft light Applies a soft, diffused light to the base color
Hard light Applies a hard, direct spotlight to the base color
Color dodge Simulates the photographic technique called dodging, which
lightens image areas by decreasing the exposure
Color burn Simulates the photographic technique called burning, which
darkens image areas by increasing the exposure
