Scanning Images: Mac Users
Scanning images on a Mac is pretty straightforward. Peripheral devices, such as scanners, use the TWAIN compliant software to acquire images and import them into Photoshop. TWAIN is a cross-platform standard that ensures that the software you install on your computer works correctly and consistently. To find out more about the TWAIN standard, you can visit www.twain.org.
To scan and import an image on a Mac, follow these steps:
Make sure your scanner is on and launch Photoshop cs .
Choose File>Import to view the submenu shown in Figure 10-10.
Figure 10-10: The Import submenu shows the TWAIN compliant devices installed on your computer.
Choose your scanner from the Import submenu.Your scanner’s software takes over, opening the appropriate dialog box, similar to Figure 10-11.
Figure 10-11: Use your scanner’s software to select settings and scan the image.
Follow the steps outlined by your scanner’s software to import the image.Don’t forget to set the resolution of your scan. Select 96 ppi for Web graphics, 300 ppi for a typical printed page, or 720 ppi or 1200 ppi for a fine photographic print.When your scanner finishes acquiring the image, the scanner’s dialog box closes and the scanned image imports and opens in Photoshop.
Try scanning objects and other items not normally used for a scan. This can come in handy when trying to design three-dimensional objects in Photoshop. For instance, if you’re working on a project that includes cubes or spheres, you can scan some blocks or balls to use as a pattern to trace (see the following figure).
