Using Photoshop
  • Adobe Photoshop software helps you work more
    efficiently, explore new creative options, and
    produce the highest quality images for print, the
    Web, and anywhere else. Create exceptional
    imagery with easier access to file data
    streamlined Web design faster,
    professional-quality photo retouching and more.

Viewing at Actual Size
  • Once your image is open you may notice the image
    is smaller then it was scanned, note the percent
    size on the bar at the top of your image.
  • You may wish to view the image at its actual size

The information bar at the top of each image
contains the file name, the percent of actual
size at which the image is viewed and the color
type. In this example the file name is
EiffelTower.tif, the image is currently viewed at
66.7 of its actual size and the type of picture
is Gray scale. Photos and graphics are usually
viewed in RGB format.
25
Viewing at Actual Size
  • To view your image at its actual size click View
    then select Actual Pixels or press AltCtrlO

Click View and then Actual Pixels
26
Resizing Image
  • Now that the image is actual size, you may wish
    to make it small enough to email, put on a disk,
    or on the internet.

    Image then select Image Size.

Click Image then select Image Size
27
Resizing Image
  • The Image Size window allows you to resize your
    image
  • Insure the Constrain Proportions box is checked
    before changing the height or width to maintain
    the current proportions of your image

Check the Constrain Proportions box to maintain
the image proportions during resizing
28
Resizing Image

  • Notice that when you reduce the size of the image
    you also reduce the size of the file. Conversely
    if you increase the image size you will also
    increase the file size.
  • When you are satisfied with your image and file
    size click OK

Note the change in file size when you change the
image size. In this example the original file
was 270K while the resized image is only 59K
When finished click OK

    in Scanwizard.

You may need to minimize Omnipage to finish
scanning.
Once scanning begins a progress bar will appear

    the Document Manager window on the left
  • It is possible to scan multiple pages and save
    them into one document. The Document Manger
    window will allow you to select any page if
    changes are required

45
Perform OCR
  • We are now ready to perform the OCR step. OCR
    stands for optical character recognition this
    branch of computer science involves reading text
    from paper and translating the images into a form
    that the computer can manipulate (i.e. a text
    file)

46
Perform OCR
  • It is possible to select from many different
    document layouts when performing the OCR step.
    The Automatic setting is suggested for its ease
    of use

Select the type of document on which the OCR
proofing is to be performed. The Automatic
setting is suggested for its ease of use.

    program window.

    proofing process by clicking on the Cancel button

Once proofing begins a progress bar will appear

OCR Completion
  • If no errors were detected after OCR proofing is
    complete then the pop-up window shown will appear

  • If no errors were detected you may skip ahead to
    the saving step

If no errors are found a pop-up window will
indicate proofreading is complete
50
OCR Correction
  • If errors are detected in the document, the OCR
    Proofreader window will appear
  • It is possible to change or ignore each error
    found during OCR proofing. You may opt to skip
    this correction step, save the document and edit
    the errors later with a document editing program
    such as Word or WordPerfect

If errors are found in the document the OCR
Proofreader window will appear. The unrecognized
character will be shown both as the highlighted
portion of the scan and a best guess by the
computer in the Contains unrecognized character
field.
51
OCR Correction
  • Many errors in proofing are caused when copied
    documents are scanned. Fuzzy or blurred words
    and letters can cause the proofing software to
    detect characters that are not actually present
  • To fix these proofing errors simply type in the
    correct letter or word(s) in the Change to field
    then click Change

In this example the computer has detected an
error when scanning the R in the text
INFORMATIC. The OCR proofreader believes the
R to be Rigt. To change this to the correct
character enter the correction R into the Change
to field then click the Change button.
52
Corrections Completed
  • When all errors have been addressed the
    completion window will be displayed
  • Click OK to continue

When all errors have been corrected or ignored
the proofreading is complete window will appear.
Click OK
53
Saving
  • You may now place a second or additional page
    onto the scanner and begin the process over again
    until all pages in your document have been
    scanned and proofed.
  • If you have only one page or have completed
    scanning all pages, you may now save your
    document.
  • Click on the Save as File icon below 3. Export
    results

Click on the icon located below 3. Export Results
to save
54
Saving Scanned Document
  • Select the location for your document to be saved
    in the Save in field.
  • Name your file in the File name field
  • Select the format to desired for saving in the
    Save as type field

Troubleshooting
56
Troubleshooting
  • Cannot Find Scanner, Please use SCSI Probe. -gt
    Look behind the scanner and see if the black
    power cable is plugged into the scanner. The
    cable should be plugged in left of the white
    cable at the back of the scanner system.
  • After successfully scanning my media into the
    computer I am not able to access it even though I
    can see it. After scanning your media it is
    recommended that you close the Microtek Scan
    Wizard box and then you will be able to access
    your media files and also edit them.
  • I scanned my media but its scanned upside down
    or at a weird angle. The best way to solve this
    is to Click on Image -gt Rotate Canvas -gt The
    direction you want it to rotate.

Questions Answers
58
Question and Answer
  • Q. How do I get the highest quality copy of my
    original?
  • A. The simplest thing you can do is go to the
    Advanced Control Panel and click on the options
    menu. Open the More.... item. Under scan quality
    choose the Best Quality option. Save the image as
    a JPEG file type.
  • Q. What is the ideal resolution for copying a
    photo?
  • A. 300 dpi is enough resolution for most printers
    to create an accurate 4"x5" copy of a 4"x5"
    original. To blow-up an image, scan at a higher
    resolution and use the Scale Output feature in
    ScanWizard 5 to blow up the image. For Advanced
    Panel users, change the Scaling value to increase
    the size of the image and scan at a higher
    resolution. The ideal resolution, when scaled,
    should result in an image that is about 300 ppi.

59
Question and Answer
  • Q. How do my friends find the images I sent them?
  • A. First, write down the name of the file. Have
    your friend search for the name of that file on
    their system. For help finding files, please
    consult the help files or documentation for the
    operating system that shipped with your computer.
  • Q. How do my friends open the images I sent them?
  • A. Find an image-viewing application on your
    system. Recent Windows and Macintosh operating
    systems ship with at least one viewer. Consult
    your documentation and open this application.
    Find the file that was sent on your system. Use
    the image viewing application to open the file.

60
Question and Answer
  • Q. How do I switch between the Standard and
    Advanced Control Panel?
  • A. Click on the first icon along the top of the
    ScanWizard 5 scanning software to switch between
    Standard and Advanced control panels.
  • Q. What is the best resolution to scan an image?
  • A. It is recommended to scan at 100 ppi for a web
    page image. Anything above 100 ppi would be good
    for documents and presentations. A word of
    caution though, the bigger the resolution the
    bigger the picture and also increase in size.
