Scanning magazine photos is a challenging task but there are tricks to get a great outcome. The scanner bed should always be clean before any scanning process to avoid mandatory touch-ups afterwards. The photos should be flat and unwrinkled, without any bumps that could affect the quality of the digital image. This can be easily done by placing the photos underneath some books. You should always use a photograph setting to auto-correct the color. Previewing and fixing double-sided scan issues by adding an extra sheet of paper behind the photo will help you save valuable time to make all the adjustments before the scan.
