Retouching and transforming
The retouch and transform features in Adobe® Photoshop® CS3 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® CS3 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.
