Specifying pattern smoothness and detail

The Smoothness and Sample Detail options in the Pattern Maker dialog box let you control the parameters that Photoshop uses to generate a pattern. The default settings work well for most samples, so don’t change these settings unless you get a poor result.

Smoothness If the pixels in the sample lack contrast, the Pattern Maker may introduce unwanted edges into the generated pattern. Increasing the Smoothness value decreases the prominence of edges within a generated tile.

Generated pattern with Smoothness of 1 and Smoothness of 3

Sample Detail If the sample contains details that are cut up in the generated pattern, increase the Sample Detail value.

Example of sampled image

Generated pattern with Sample Detail of 5 and Sample Detail of 15

Note: Increasing the Smoothness and Sample Detail values results in slower pattern generation.

Choosing foreground and background colors

Photoshop uses the foreground color to paint, fill, and stroke selections and the background color to make gradient fills and fill in the erased areas of an image. The foreground and background colors are also used by some special effects filters.

You can designate a new foreground or background color using the eyedropper tool, the Color palette, the Swatches palette, or the Adobe Color Picker.

The Info palette, the Color palette, and the Adobe Color Picker let you display color values using a number of color models. (See “About color modes and models (Photoshop)” on page 86.)

You can also specify the area sampled by the eyedropper tool. For example, you can set the eyedropper to sample the color values of a 3-by-3-pixel area under the pointer. Modifying the sample size of the eyedropper affects the color readouts displayed in the Info palette.

To select the foreground or background color:

1Select the eyedropper tool .

2To change the sample size of the eyedropper, choose an option from the Sample Size menu:

Point Sample to read the precise value of the pixel you click.

The Color palette may display the following alerts when you select a color:

In Photoshop, an exclamation point inside a triangle appears above the left side of the color ramp when you choose a color that cannot be printed using CMYK inks.

For more information, see “Identifying out-of-gamut colors (Photoshop)” on page 136.

A cube appears above the left side of the color ramp when you choose a color that is not Web-safe. For more information, see “Using Web-safe colors” on page 262.
