Digital restoration work starts by getting the image information into the computer and ends by making a print. The start of the process is where the original is scanned in. The quality of the scan is very important because this is where the final quality comes from to do retouching work. A good scan will capture the right amount of color, tone, and image resolution for the retouching process this will save you hours trying to recreate information that wasn’t scanned properly in the first place. A desktop flatbed scanner can scan in originals and is necessary for retouching. Some flatbed scanners come with an optional transparency unit for scanning negs. or slides.
