    Photographers: How to Deal With Scanning issues

     

    If you do a fair bit of scanning, you’ll encounter moiré patterns, which are caused by a misalignment between pixels and a scanning device or camera, making patterns turn into rainbow-colored streaks.

    Here are a couple of quick fixes.

    1. Scan the document at a higher resolution than what you need. For example, if you’re scanning an image for the Web, scan at 200 dpi instead of 96 dpi, which you would normally use. Once the image is scanned, reduce the image to the size you need.

    2. With the document flat on the scanner surface, rotate it on an angle from the vertical, and then scan it. After the scan comes up in your image manipulation software you can rotate the scan back to the vertical.
