The following steps are for starting Photoshop CS4 using the computers in the ITS Training Program computer labs. The steps for starting the program at home or on other computers may be slightly different. Photoshop works with digitized images which can come from a digital camera, a scanner, other drawing programs, or captured video stills. Once the desired digital image has been imported to a computer, users can open it in Photoshop for further viewing and editing. Created by the ITS Training Program at CSULA for students.
