Quality Standards: scanning

Artifacts: All scanners, both high quality and the cheapest ones in the images may introduce imperfections or streaks, sometimes only visible when the file is scanned and printed at actual size. If this happens, you can try to rescan the image, but perhaps the best solution is to buy a scanner.

Noise: occurs primarily in low light or in the presence of shadows, usually due to poor quality of the scanner. Sometimes, the problem of background noise can be corrected with a program to reduce background noise.

Drum Scanner:

To get quality scans, are essential drum scanner. The operation of this type of scanner depends on a different process than traditional desktop scanner, because it is based on the positioning of slides and negatives on a drum acrylic that allows you to accurately capture all the details of the original image at high resolution.

Oversampling: Oversampling is the process by which a scanner repeated several times to scan an image and then combines the data to produce an average of differences. This method allows for cleaner scans, especially in low lighting and shaded areas. This feature is available in most of the more expensive scanners, but if you do not have this option, you can repeat manually scan the image several times with a range of different shades and then process the images trying to change the settings of opacity and blending .
