Channel blend
With Channel blend, you can set how the current layer is blended into
the layer beneath. Different blending methods can be set from the Blend
Mode dropdown list. The Blend Factor slider sets the opacity of the
current layer.
The choices are:
- Normal
- Darken
- The Darken method makes layers dark or darker.
- Lighten
- The Lighten method makes layers light or lighter, brightening
the components.
- Multiply
- The Multiply method 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.
- Screen
- The Screen method brightens by lighting the lower layer based
on the lightness of the upper layer.
- Overlay
- The Overlay method multiplies or screens the colors, depending
on the base color. Patterns or colors overlay the existing pixels while
preserving the highlights and shadows of the base color. The base color
is not replaced but is mixed with the blend color to reflect the
lightness or darkness of the original color.
- HardLight
- The HardLight method throws distinct shadows. It comes from a
point light source such as the sun or an electronic flash.
- SoftLight
- The SoftLight method throws light shadows.
- Difference
- With the Difference method, if you place an all white layer
below a layer using the difference method, you get a negative image.
- Dodge
- The Dodge method can simulate the effects of underexposure by
lightening the base color.
- Burn
- The Burn method affects the look of a high intensity light. It
increases exposure in certain areas to darken the print.
