Using the Scanner

  1. We should leave the scanner workstation ``open'' and establish a sign-up sheet for scanning.

  2. Students can use instructor's workstation.

  3. Logging-on is a little different on the instructor's machine.

Scanner instructions:

  1. Carefully place your image on the scanner bed. ``Ground zero'' is the upper right-hand corner. The image should be placed face-down, as if you were using a copier.

  2. Open Paint Shop Pro.

  3. From File menu, choose Acquire. A scanner window should pop up.

  4. The scanner should automatically preview your image. If not, click the Preview button.

  5. Your image should now appear in the window. Notice that there is a tiny ``frame'' surrounding the image. Drag the frame to zero-in on the portion of the image in which you're interested.

  6. You can use the Zoom button to zoom in on your selection and fine-tune your frame positioning.

  7. Click the auto-exposure button (it's between the brightness and contrast controls.

  8. If you'd prefer to see the size of your image in inches, open the Custom menu, choose Image size and change Units to inches.

  9. You may now adjust the image size. If you think you'll be using more than one size of an image in your work, use the scanner to make a few copies of the images, each copy at a different size. Using the scanner to re-size the image produces the best results.

  10. Click the Final button. Save the image to a folder on your N: drive. Photographs should be saved a JPEG files. Other images should be saved as GIF files. If these image formats aren't available, save your image as a TIFF file.

Some examples:

  1. normal.tif --- 100% size, 3.56 x 4.91 in., 267 x 368 pixels.

  2. little.tif --- 16% size (smallest possible), .57 x .78 in., 43 x 59 pixels. My ``thumbnail'' image.
