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 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, Contrasty, Enlarged, Stippled,
Horizontal, Vertical, and Speckle, available from the Grain Type menu.
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 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.
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 video image. You can choose to
replace the discarded lines by duplication or interpolation.
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.
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 Create a Custom filter .
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 from an image and has an effect opposite to that of the Gaussian Blur filter.
It is helpful to apply the High Pass filter to a continuous-tone image before using the Threshold command or converting the image to Bitmap mode.
The filter is useful for extracting line art and large black-and-white areas from scanned images.
The Maximum and Minimum filters are useful for modifying masks. The Maximum filter has the effect of applying a
spread (dilation)—spreading out white areas and choking in black areas. The Minimum filter has the effect of applying a choke (erosion)—
shrinking white areas and spreading out the black areas. Like the Median filter, the Maximum and Minimum filters operate on selected pixels.
Within a specified radius, the Maximum and Minimum filters replace the current pixel’s brightness value with the highest or lowest brightness value
of the surrounding pixels.
