Overview Photoshop lets users edit digital photographs and create original artwork including type designs. In J210, we will work with a relatively small range of its functions, just enough for you to edit your digital photographs and prepare them for your slide show. If you want to learn more about this industry standard application, consider taking the upper level photojournalism and graphic design courses. This handout covers: 1) rotating, 2) cropping, 3) adjusting exposure levels, 4) adjusting color balance, 5) using the Levels adjustment, 6) using Levels, the History Brush and the History palette in combina- tion, and 7) optimizing images for the Web. Understanding Photoshop. A digital image file in Photoshop comprises thou- sands to millions of small, square Picture Elements, called pixels. They are arranged in a matrix of rows and columns. Each pixel is filled with a color or with black, white or a shade of gray. Each pixel exists where a row and column intersect, meaning it can be identified with horizontal and vertical coordi- nates. Because of this, you can select pixels and edit them. Editing changes can be made to a single pixel, a group of pixels or the entire file. Photojournalism ethics Photoshop allows users to change the attributes of each pixel and therefore, to alter the contents of photographs—adding, deleting, moving or clon- ing items—in ways that are ethically unacceptable in journalism. Most photojournalists, however, do consider it acceptable to adjust some global charac- teristics so long as the content of the image remains the same. These adjustments compensate for short- comings in image capture . Adjustments include correcting exposures of entire images, lightening and darkening selected areas, and correcting color balance. Cropping, that is removing parts of an image around its edges, is also widely practiced. These adjustments can make the difference between a muddy image and a crisp picture that communi- cates its message clearly. Note. Not all photographs can be saved. Some exposures are too far outside the acceptable range to be rescued. Ethics intersects with aesthetics. Keep your changes subtle and undetectable. Don’t overdo. Don’t be obvious. Don’t try to make reality perfect. Controlling the software You control Photoshop through mouse clicks, menus, keyboard shortcuts, palettes, dialog pan- els, and tools in an interface that’s very similar to other Adobe CS programs like Bridge. For example, under the File menu, the New, Open, Save As and other familiar menu commands perform the same functions as in all software. Such keyboard com- mands as z +c, z +x, z +v and z +z perform the same editing functions. Selecting menu items with an ellipse (…) opens a dialog panel. Selecting menu
