Effects and filters
Last updated 9/13/2015
Stamp
The Stamp filter simplifies the image so that it seems made with a rubber or wood stamp. You can set the smoothness,
and the balance between light and dark. This filter works best with black-and-white images.
Torn Edges
The Torn Edges filter reconstructs the image as ragged, torn pieces of paper, and then colorizes the image using the
foreground and background color. You can set the image balance, smoothness, and contrast. This filter is particularly
useful for images consisting of text or high-contrast objects.
Water Paper
The Water Paper filter uses blotchy daubs that appear to be painted onto fibrous, damp paper, causing the colors to flow
and blend. You can set the paper’s fiber length, brightness, and contrast.
Noise filters
Add Noise
The Add Noise filter applies random pixels to an image, simulating the result of shooting pictures on high-speed film.
This filter can also be used to reduce banding in feathered selections or graduated fills, to give a more realistic look to
heavily retouched areas, or to create a textured layer. You can set the amount of noise, the type of noise distribution,
and color mode. The Uniform option creates a subtle distribution appearance and Gaussian creates a speckled
distribution look. Monochromatic applies the filter using the existing tones of the image without changing the colors.
Despeckle
The Despeckle filter detects the edges in a layer (areas where significant color changes occur) and blurs all of the
selection except those edges. This blurring removes noise while preserving detail. You can use this filter to remove
banding or visual noise that often appears in scans of magazines or other printed materials.
Dust & Scratches
The Dust & Scratches filter reduces visual noise by changing dissimilar pixels.
Median
The Median filter reduces noise in a layer by blending the brightness of pixels within a selection. The filter searches for
pixels of similar brightness, discarding pixels that differ too much from adjacent pixels, and replaces the center pixel
with the median brightness value of the searched pixels. This filter is useful for eliminating or reducing the appearance
of motion in an image, or undesirable patterns that may appear in a scanned image.
