BCC Apply Modes
Category: Common Controls
Effect Name: BCC Apply Modes
The BCC Apply Modes, part of BCC Common Controls, are present in many effects. Apply Modes control the blending of two images, giving the effects many additional creative possibilities. The Apply Mode menu may contain any or all of the apply modes described below.
Available Apply Modes
Normal: Applies the light or filter directly to the source image, replacing the source pixels with filtered pixels.Lighten: Compares the color channels values in the original pixels and in filtered pixels, and chooses the lighter (higher) value for each channel in each pixel. If a pure red pixel is applied to a pure blue pixel, the result is pure magenta.Darken: Compares the color channels values in the original pixels and in filtered pixels, and chooses the darker (lower) value for each channel in each pixel. If a pure red pixel is applied to a pure blue pixel, the result is black.Multiply: Applies the light or effect to the source as if it were a transparency placed over the source. The resulting image is darker than either. If a pure red pixel is applied to a pure blue pixel, the result is black. If a 50% gray pixel is applied to another 50% gray pixel, the result is 25% gray.Screen: Applies the light or effect to the source as if a photographic double image was taken of the light or effect and the source. The resulting image is lighter than either the light or effect or the source. If a pure red pixel is applied to a pure blue pixel with Screen, the result is magenta. If a 50% gray pixel is applied to another 50% gray pixel with Screen, the result is 75% gray.Difference: Outputs the difference between the light or filtered color and the source color for each channel.Lighter: Uses the lighter of the source and filtered colors for each pixel for all channels.Darker: Uses the darker of the source and light or filtered colors for each pixel for all channels.Scale Multiply: A variation of Multiply that produces a brighter image than the standard Multiply.Scale Screen: A variation of Screen that produces a darker and less washed-out image than the standard Screen.Difference X 2: A variation of Difference that produces a more intense effect than the standard Difference.Difference X 4: A variation of Difference that produces an even more intense effect than Difference X 2.Add: Adds the light or filtered output with the source.Subtract: Subtracts the light or effect from the source.Overlay: Layers the light or effect over the source.Soft Light: Simulates shining a diffuse light on the source image.Hard Light: Simulates shining a harsh light on the source image.Hue: Creates a composite color for each pixel that takes its Hue value from the light color or filtered output.Saturation: Takes the Saturation of each pixel from the light color or filtered output.Color: Takes the Color for each pixel from the light color or filtered output.Luminosity: Takes the Luminosity for each pixel from the light color or filtered output.Transparency: Used in Light filters and other lighting effects. Increases transparency in lit regions.Opacity: Used in Light filters and other lighting effects. Increases opacity in lit regions.Boost Expo 1: Blends the color channels in the source and filtered pixels by subtracting an offset value.Boost Expo 2: Similar to Boost Expo 1, except that this mode uses different offset and exponent values.Boost Eq Power +: Uses an algorithm modeled on the audio concept of an equal power crossfade.Boost Eq Power β: Similar to Boost Eq Power +, but emphasizes dark pixels.Boost Bias: Increases the contrast of the pixels whose channel values are highest.50β50 Mix: Reduces the opacity of the source and filtered pixels by 50% and blends them equally.Behind: Composites the light behind the image that is lit.In Front: Composites the light in front of the image that is lit.None: Outputs the effect and ignores the underlying layer.Note: In all boost apply modes, if the top and bottom color are identical, the output color will be the same as the top and bottom.
