Classical Halftone Patterns for Photoshop CS, CS2 and CS3
This solution works on Mac and PC and includes 40 halftone patterns for converting continuous tone images into Classical Halftone and Classical Line line art images. No plugin or image mode conversion required. With this method you can do anything the Classical Halftone plugin does. It's up to you wich method you prefer and although using a plugin is convenient, you will have to use these patterns if you work on a Mac. You may also prefer this line art conversion method because it is flexible, non-destructive and remains completely editable (especially with Photoshop CS3 Smart Filters). The patterns are designed to simulate the maximum possible number of gray levels at a given halftone screen.
