Retouching and transforming

Last updated 12/5/2011

To make a transformation, first select an item to transform and then choose a transformation command. If necessary,

adjust the reference point before manipulating the transformation. You can perform several manipulations in

succession before applying the cumulative transformation. For example, you can choose Scale and drag a handle to

scale, and then choose Distort and drag a handle to distort. Then press Enter or

Return to apply both transformations.

Photoshop uses the interpolation method selected in the General area of the Preferences dialog box to calculate the

color values of pixels that are added or deleted during transformations. This interpolation setting directly affects the

speed and quality of the transformation. Bicubic interpolation, the default, is slowest but yields the best results.

Note: You can also warp and distort raster images using the Liquify filter.

Scale Enlarges or reduces an item relative to its reference point, the fixed point around which transformations are

performed. You can scale horizontally, vertically, or both horizontally and vertically.

Rotate Turns an item around a reference point. By default, this point is at the center of the object; however, you can

move it to another location.

Skew Slants an item vertically and horizontally.

Distort Stretches an item in all directions.

Perspective Applies one-point perspective to an item.

Warp Manipulates the shape of an item.

Rotate 180, Rotate 90 CW, Rotate 90 CCW Rotates the item by the specified number of degrees, either clockwise or

counterclockwise.

Flip Flips the item vertically or horizontally.
