Scanning Basics

INTRODUCTION - AVAILABLE SOFTWARE - BEGINNING A SCAN - SCANNING IN SIMPLE MODE - SAVING YOUR IMAGE


INTRODUCTION

Each workstation of the lab is equipped with a Canon CanoScan LiDE 20 flatbed scanner. The scanner features 48-bit color and up to a 600x1200 d.p.i. resolution.

AVAILABLE SOFTWARE

The primary piece of software used for scanning and manipulating images is Adobe Photoshop. Images can also be scanned within Vegas Video for use in video editing projects (see Advanced Scanning).

BEGINNING A SCAN

  1. Open the scanner lid and place your original document face down on the glass, aligning the top left corner of your document to the corner with the sideways arrow.
  2. Start Photoshop by clicking Start > Programs > Adobe Creative Suite 2 > Adobe Photoshop CS2.
  3. From the File menu, select Import, then CanoScan LiDE 20.
  4. The ScanGear CS window appears. There are two modes available for scanning -- simple and advanced. Simple mode will usually appear as a default, with a blue-on-white menu (see below). If it appears in advanced mode, there will be a button at the bottom right corner of the window that says "simple mode." Clicking it will bring you to simple mode.

SCANNING IN SIMPLE MODE

Simple mode should suffice for most users. It offers an easy-to-use menu to guide you through scanning. The menu at right consists of four steps.

    1. SELECT SOURCE. No choice is needed. The only option (platen) is already selected.
    2. TYPE OF ORIGINAL. Choose from this menu what type of original document you are scanning. Your options are Photo (Color/300 dpi), Magazine (Color/150 dpi), Newspaper (Black and White/300 dpi), or Document (Grayscale/300 dpi).
    3. DISPLAY TEST IMAGE. When you click the Preview button, the scanner will scan and display an image in the left part of the ScanGear window. You can use this image preview to crop your image to size before committing to the final scan. Place your mouse cursor over the dashed selection box, click and drag it vertically and/or horizontally until the box surrounds the outer edge of your document.
    4. PERFORM SCAN. Clicking the Scan button performs the scan, places the image into Photoshop.

If the ScanGear window does not close on its own, click the X button in the top right corner of the window.

SAVING YOUR IMAGE

There are a variety of ways to save the files you scan. The easiest and safest way to save your images in the media lab is to use a CD, DVD, or Compact Flash card. These ways will allow you to not only take your files with you, but to ensure that your files will not be manipulated or accidentally erased by other users.

Compact Flash cards are more expensive, smaller, and would typically require the purchase of a USB "reader" if you would want to access your images at home.

CD-R's and CD-RW's are a great inexpensive option for storing and retrieving images on the majority of today's computers. Blank CD's typically come in smaller packs with jewel cases or on spindles of between 25-100 without jewel cases. They hold 650-700 MB of data, depending on the disc.

To save your scanned image to Compact Flash card:

    1. Insert the Compact Flash card into the appropriate drive.
    2. Click File > Save As...
    3. In the Save As window, click on the My Computer tab on the dark gray bar on the left.
    4. Double click Compact Flash to select which a drive on which your image will be saved.
    5. On the bottom of the Save As window, make sure that JPEG is selected from the Format pull-down box.
    6. In the File name box, type in the name you wish to save your image and click Save.
    7. A JPEG Options window will appear. Within it are three subsections.
      - Image Options allows you to specify the image quality you want for your file. You can specify a number from 1 to 12 (low to high quality), select a quality from the drop-down box, or adjust the slider. Selecting lower quality shrinks your file size, allowing you more disk space for storing other data, however your image quality will be inferior. Conversely, selecting a higher quality renders both a better looking image and a much larger file size. You may want to select a higher quality if you intend to do advanced things like image touch-ups or large-scale printing, whereas you might choose a lower quality for use on the web.
      - Format Options lets you choose how your file is saved. Typically, Baseline Standard is the best way to save.
      - Size tells you the file size of your image, as well as the estimated time it would take to download from the Internet, depending upon the type of modem selected. (Note: A size preview will not be generated unless the Preview checkbox is checked.)
    8. Click OK. Your file is now saved.

To save your file to the hard drive:

Each workstation is equipped with a hard drive (Drive D) which is solely for storing work files. You can save your files to the hard drive of the workstation you're using. However, other users may accidentally or intentionally modify your files, or at times the lab assistant may need to remove files if the drive becomes full. It's always a good idea to make a copy of your files to a disk.

    1. Click File > Save As...
    2. In the Save As window, click on the My Computer tab on the dark gray bar on the left. Your window should look like the example to the right.
    3. Double-click on the Hard Drive (Drive D).
    4. Click the New Folder button (the second button from the right on the top part of the window; see example).
    5. A new folder will appear , prompting you to name it. Type in your name.
    6. Your new folder will then appear with the new name you've given it.
    7. On the bottom of the Save As window, make sure that JPEG is selected from the Format pull-down box.
    8. In the File name box, type in the name you wish to save your image and click Save.
    9. A JPEG Options window will appear. Within it are three subsections.

To save your images to a CD or DVD:

You must first save your files to the hard drive, as directed above.

    1. Open SonicDigital Media Home from the start menu.
    2. Select Data on the left hand column.
    3. Select Data Disc.
    4. Insert a blank CD or DVD in the front of the computer.
    5. Next click Add Data to add your files.
    6. Navigate to your folder on the Data (D:) Drive.
    7. Click on each file you want added to the CD or DVD.  You can add more than one by holding down the CTRL button.
    8. Notice the time indicator disc in the lower left corner.  Each time you add a new file, the disc fills indicating how long your CD or DVD is.  It also estimates how much space is left on the disc.
    9. Once you are done compiling your CD of DVD, click the Red Button in the lower right corner.  Click YES to continue.
    10. Once Sonic is done burning your CD or DVD click done.
    11. Your CD or DVD should automatically eject.  Take out your CD or DVD and close the drive door.
