Page 1 – March 21, 2003 Scanning • Output Resolution • Image/Print Size The secret to publishing your photos is in understanding resolution and image/print size. When you scan a photo or take a picture with a digital camera, you are given options that will affect the file size and finished quality of the image. Resolution ÿ Screen images (web pages & slide shows) look good at a resolution of 72 – 75 pixels or dpi. ÿ Pictures for classroom publications (reports and newsletters) may be quite acceptable at a resolution anywhere between 72 and 150 pixels or dpi. ÿ Photo quality printed images should have a resolution of 300 – 600 pixels or dpi. Adjusting Settings in the ScanGear Window Before you click the Scan button, a number of adjustments can be made to fine-tune the output resolution and size of the final scanned image. 1. Choose the desired Output Resolution from the pop-up. 2. After you click Preview, you will see the image surrounded by a dotted selection rectangle or marquee. The window will also give you information on the Selection size (original or cropped image) and the Print (output) size: Size viewed in inches Size viewed in pixels Page 2 – March 21, 2003 Cropping (Optional) 1. Use the Selection Marquee (dotted rectangle) and pull in the sides of the rectangle around your image to define the area and width/height ratio of the finished image. 2. Note that the Selection Width and Height change as you move the sides of the Marquee. Image/Print Size (Optional) ÿ Enter new numbers for the Print Size Width or Height. Most computers have a screen size ratio of 4:3. An ideal size for images that you plan to put in a PowerPoint slideshow is 640 pixels wide by 480 pixels high. You will have to crop away some of the width of a standard 6 inch by 4 inch photo to get a 4 by 3 ratio. Scan It! After you have made all of the desired adjustments to the output resolution and image/print size, you are ready to complete the image scan. Click the Scan button. Remember to close the ScanGear window to find your scanned image in Photoshop Elements. Adjusting Image Quality and Saving in Photoshop Elements Two quick adjustments will often improve your image quality immensely! They are: Auto Levels and Auto Color Correction.
