  20. Using Photoshop

  21. 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.

  22. Opening Photoshop 6.0.1 • If you have automatically opened Photoshop during scanning you may skip ahead. If you have not you will need to open the Adobe Photoshop program. • Click on the Start button • Click on Programs • Click on Adobe Photoshop 6.0 Click Adobe Photoshop 6.0 to open program

  23. Opening a File • To open a picture click File and then select Open or press Ctrl+O. Click File and then Open

  24. 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 it’s 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 it’s actual size click View then select Actual Pixels or press Alt+Ctrl+O 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. • To change the actual size of an image click on 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 • It is also possible to change the resolution of your image from this window if desired To resize your image simply enter a new width or height and press Enter, the image will automatically resize Check the Constrain Proportions box to maintain the image proportions during resizing

  28. Resizing Image 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 • Change the width and the height will change automatically and visa versa if you have checked the Constrain Proportions box • 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 When finished click OK

  29. Saving • To save your file select File and then Save or press Ctrl+S • If you wish to save for use on the web follow the steps outlined in the following slides. Click File then select Save

  32. Saving for Web Use • Depending on the type of image, there are different save options. • Photos should be saved as a .jpg, medium quality works best for internet and email use • .gif format is for simple graphics, cartoons and line-drawings It is possible to save your image in one of several formats shown in the Settings menu. JPEG Medium is best for internet and email.

  33. Saving for Web Use • By clicking on the 4-Up tab you can compare quality and file size of different quality levels. Click 4-Up to compare the quality and file size of several different quality levels at once

  41. Setting Page • In our first step we will select what format to scan our document in. • By clicking on the small arrow next to the 1. Get Page icon we may scan our document in… • Black & White for normal documents • Grayscale for documents with black and white graphics • Color for documents with color graphics or text Select the format the document is to be scanned in.

  42. Get Page • Once you have selected the format click on the icon located below 1. Get Page Click on the icon located below 1. Get Page to begin scanning

  43. Get Page • Scanning will now begin and a progress bar will be displayed at the bottom of the OmniPage program window. • OminPage Pro uses the ScanWizard program discussed earlier to scan your document.

Scanned Document • The document will appear once scanning is complete • A thumbnail of the document will also appear in 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.

  48. OCR Operating • OCR Proofing will now begin and a progress bar will be displayed at the bottom of the OmniPage program window. • If desired it is possible to terminate the OCR proofing process by clicking on the Cancel button Once proofing begins a progress bar will appear

  49. OCR Completion • If no errors were detected after OCR proofing is complete then the pop-up window shown will appear • Simply click OK to continue • 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 characterwill be shown both as the highlighted portion of the scan and a best guess by the computer in the Contains unrecognized character field.
