Adobe Photoshop is a powerful image-editing program that allows you to edit and colorize images, retouch proofs, create original or composite artwork and produce prepress color separations. Photoshop works with bitmapped, digitized images (that is, continuous-tone images that have been converted into a series of small squares, or picture elements, called pixels). You can also work with vector graphics, which are drawings made of smooth lines that retain their crispness when scaled. You can create original artwork in Photoshop, or you can import images into the program from many sources, such as:
● Photographs from a digital camera.
● Commercial CDs of digital images.
● Scans of photographs, graphics, or other documents.
● Captured video images.
