Texture filters

Use the Texture filters to simulate the appearance of depth or substance, or to add an organic look.
Paints an image onto a high-relief plaster surface, producing a fine network of cracks that follow the
Craquelure
contours of the image. Use this filter to create an embossing effect with images that contain a broad range of color or
grayscale values.
Adds texture to an image by simulating different kinds of grain—Regular, Soft, Sprinkles, Clumped,
Grain
Contrasty, Enlarged, Stippled, Horizontal, Vertical, and Speckle, available from the Grain Type menu.
Mosaic Tiles Renders the image so that it appears to be made up of small chips or tiles and adds grout between the
tiles. (In contrast, the Pixelate > Mosaic filter breaks up an image into blocks of different-colored pixels.)
Breaks up an image into squares filled with the predominant color in that area of the image. The filter
Patchwork
randomly reduces or increases the tile depth to replicate the highlights and shadows.
Repaints an image as single-colored adjacent cells outlined in the foreground color.
Stained Glass
Applies a texture you select or create to an image.

Video filters

The Video submenu contains the De-Interlace and NTSC Colors filters.
Smooths moving images captured on video by removing either the odd or even interlaced lines in a
De-Interlace
video image. You can choose to replace the discarded lines by duplication or interpolation.
NTSC Colors Restricts the gamut of colors to those acceptable for television reproduction, to prevent oversaturated
colors from bleeding across television scan lines.

Other filters

Filters in the Other submenu let you create your own filters, use filters to modify masks, offset a selection within an
image, and make quick color adjustments.
Custom Lets you design your own filter effect. With the Custom filter, you can change the brightness values of each
pixel in the image according to a predefined mathematical operation known as convolution. Each pixel is reassigned
a value based on the values of surrounding pixels. This operation is similar to the Add and Subtract calculations for
channels.
You can save the custom filters you create and use them with other Photoshop images. See also "To create a Custom
filter" on page 526.
High Pass Retains edge details in the specified radius where sharp color transitions occur and suppresses the rest of
the image. (A radius of 0.1 pixel keeps only edge pixels.) The filter removes low-frequency detail in an image and has
an effect opposite to that of the Gaussian Blur filter.
