Image size
Mark Galer, Philip Andrews · 2004
Before retouching and enhancement can take place the ‘image size’ must be adjusted for the intended output (scanning resolution will probably require changing to output resolution). Choose Image > Image Size. This will ensure that optimum image quality and computer operating speed are achieved. Image size is described in three ways: • Pixel dimensions (the number of pixels determines the fi le size in terms of kilobytes). • Print size (output dimensions in inches or centimeters). • Resolution (measured in pixels per inch or ppi).
