Adjust the following controls for the Leave Color effect:
Amount To Decolor
Specifies how much color is removed from the layer. A setting of 100% causes the areas of the
image dissimilar to the selected color to appear as shades of gray. At 50%, those areas lose half of their color
saturation.
Color To Leave
Specifies the color that is to be left untouched.
Tolerance
Specifies how closely the effect matches colors. A value of 0% decolors all areas of the image except those
that match the Color To Leave exactly. A value of 100% causes no color change.
Edge Softness
Specifies the sharpness of the color boundaries. High values smooth the transition from color to gray.
Match Colors
Specifies the color model to use for similarity. RGB uses the RGB color space to determine which areas
are decolored. Match Colors is a strict matching technique and usually decolors more of the image than Hue. Hue
uses hue (color) to determine which areas are decolored. In other words, choosing light blue as the Color To Leave
also leaves dark blue, since both colors have the same hue.
Mosaic effect
The Mosaic effect fills a layer with solid color rectangles. It is useful for creating a highly pixelated image.
The Mosaic effect has the following settings:
Horizontal/Vertical Blocks
Specifies the number of mosaic divisions in each direction.
Sharp Colors
Gives each tile the color of the pixel in its center in the unaffected clip. Otherwise, the tiles are given
the average color of the corresponding region in the unaffected clip.
Noise effect
The Noise effect randomly changes pixel values throughout the image. The Noise effect has the following settings:
Amount Of Noise
Specifies the amount of noise, and therefore the amount of distortion, through random
displacement of the pixels. The range is 0% (no effect) to 100% (the image may not be recognizable).
Noise Type
Randomly changes the red, green, and blue values of the image’s pixels individually when Use Color
Noise is selected. Otherwise, the same value is added to all channels.
Clipping
Determines whether the noise causes pixel colors to wrap around. When the color value of a pixel gets as
large as it can be, clipping makes it stay at that value. With unclipped noise, the color value wraps around or starts
again at low values. When Clipping is selected, even 100% noise leaves a recognizable image. If you want a completely
randomized image, turn off Clipping and turn on Color Noise.
Replicate effect
The Replicate effect divides the screen into tiles and displays the whole image in each tile. Set the number of tiles per
column and row by dragging the slider.
Roughen Edges effect
The Roughen Edges effect roughs up the edges of a clip’s alpha channel by using calculations. It gives rasterized text
or graphics a naturally rough look, like that of eroded metal or typewriter text.
