ADOBE PHOTOSHOP CS2 

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.

Are useful for modifying masks. The Maximum filter has the effect of applying a choke—

spreading out white areas and choking in black areas. The Minimum filter has the effect of applying a spread—
spreading out black areas and shrinking white areas. Like the Median filter, the Maximum and Minimum filters look
at individual pixels in a selection. 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.

Moves a selection a specified horizontal or vertical amount, leaving an empty space at the selection’s original

location. You  can fill the  empty area with the  current background color, with another  part  of  the image, or with your 
choice of fill if the selection is near the edge of an image.

Prepares an image for use as a tiled background. You can blend the edges of an

image to create a seamless background. You can also create a kaleidoscopic background in which an image is flipped
horizontally and vertically to create an abstract design.

Choose Filter > Other > Custom. The Custom dialog box displays a grid of text boxes into which you can enter

numerical values.

Select the center text box, which represents the pixel being evaluated. Enter the value by which you want to

multiply that pixel’s brightness value, from –999 to +999.

Select a text box representing an adjacent pixel. Enter the value by which you want the pixel in this position multi­

plied.

For example, to multiply the brightness value of the pixel to the immediate right of the current pixel by 2, enter 2 in
the text box to the immediate right of the center text box.

Repeat steps 2 and 3 for all pixels to include in the operation. You don’t have to enter values in all the text boxes.

For Scale, enter the value by which to divide the sum of the brightness values of the pixels included in the calcu­

lation.

For Offset, enter the value to be added to the result of the scale calculation.

Click OK. The custom filter is applied to each pixel in the image, one at a time.

Use the Save and Load buttons to save and reuse custom filters.

The Digimarc filters embed a digital watermark into an image to store copyright information. 

The Vanishing Point feature lets preserve correct perspective in edits of images that contain perspective planes, for 
instance, the sides of a building or any rectangular object.
