Chapter 8: Retouching and transforming
The retouch and transform features in Adobe® Photoshop® CS4 let you alter your images to accomplish a variety of
tasks—to improve a composition, correct distortions or flaws, creatively manipulate picture elements, add or remove
items, sharpen or blur, or merge multiple images into a panorama. The Vanishing Point feature lets you retouch and
paint according to the perspective of an image. The Adobe® Photoshop® CS4 Extended version of Vanishing Point also
lets you make measurements of items in an image and export the measurements along with geometric information and
textures for use in 3D applications.

Cropping is the process of removing portions of an image to create focus or strengthen the composition. You can crop
