7. Adjust the Destination, (dpi), and "Output Size" if desired. Under destination, Photo (300 dpi) is best when printing images, while image display (150 dpi) is adequate for on-screen viewing [fig. 06].

Note: If a special size is needed, change it under Output size. Any additional adjustment options are available under the Advanced Mode tab.

Adjusting the Image Size

The size of the image you see on the screen is not the size of the printed image.

 

1. To see the printout size, click Image, then Image Size. A dialog box will appear [fig. 09].

2. Under "Document Size," adjust the size of the actual printout image by changing the numbers in the "Width," "Height," and "Resolutions" text boxes. The printout size as shown above has a Width of 5.971 inches and a Height of 6 inches, with a Resolution of 72 pixels/inch. Keep the option Constrain Proportions box checked, so the Width and Height adjust proportionally with each other when you change one of them.

 

Pixel Dimensions tells you the size of the file when you change the Document Size.

  • If the image is only for on-screen viewing, Resolution should be no more than 120 pixels/inch, because computer monitors usually cannot display differences of images with resolution above 120 pixels/inch. Lowering the Resolution also decreases the size of the file.

  • If the image is going to be printed on a fine printer, Resolution of 240 pixels/inch can be used. You can see more details of an image on a printout than on a computer monitor. However, most human eyes cannot tell the difference on images with Resolution set to above 240 pixels/inch.

 

4. Click OK when you are done adjusting the image size, or Reset if you make a mistake and want to start over.

 

Cropping The Image

 

1. Select the Crop tool, which is the third one down on the left tool pane.

 

2. Click and drag to create a rectangle with your mouse. The enclosed area is the part of the image you want to keep. The part of the image that will be cropped (removed) turns dark.

 

3. Press Enter to crop.

 

Rotating The Image

There are two ways to rotate the image:

 

1. Click Rotate Image under "Cansvas." Select one of the rotation options.

OR

2. Select the image with the Rectangular Marquee tool, which is the top left button on the tool bar. Select the tool, then use the mouse to select the entire image. Click Edit, Transform and Rotate. Use the mouse to rotate the image as desired.

 

Adjusting the Brightness/Contrast of the Image

 

1. Select the image with the Rectangular Marquee Tool. Then click Layer, New Adjustment Layer, then Brightness/Color Contrast [fig. 10].

2. Click OK [fig. 11].

3. Adjust the image accordingly. Check and uncheck the Preview box to view the image before and after the adjustment you make.

 

Saving Your Scanned Image

 

Once you are satisfied with the adjustments of your scanned image, you should save it. You can save the image to your H: drive or to a disk.

 

1. To save your scanned image for printing, select Save As under "File."

 

2. Select the desired image type Format and press Save.

 

3. To save your scanned image for the Web, go to Save For Web under "File." In the control panel on the right, the default setting is GIF. Choose your desired image type and press OK. Select the destination where you want to save the image, and click Save.
