Scan the images, saving in TIFF, BMP or PCX, but not as JPEG.If your scanner has a setting that allows you to improve shadow separation, use it.For colour pictures, set any colour controls to the default values unless you are scanning direct to a printer.On some scanners, resetting to default will give good results. Try the auto-exposure button if there is one in the software, then adjust brightness and contrast if needed.For web, create a scan with largest side around 900 pixels. For printing, scan to get 300 pixels per inch of final print size. Adjust the scanner resolution to give an appropriate file size in pixels.Otherwise use this for colour and grayscale for black and white. If you are going to use Photoshop (or other image manipulation), scan all images as ‘millions of colours’.On the preview, use the mouse to outline the desired scan area.If your picture is skewed, adjust the alignment and repeat the preview.If your scanner software does not automatically run a preview, do so (unless you are using VueScan - see Tips below.).On some scanners there is a scan button, or there may be an import function on your images processing software, or a separate scanner program. Ensure that the actual print area is parallel to the edges of the scanner. Before use, carefully clean the scanner glass with a damp cloth or glass cleaner and dry.You need a flatbed scanner installed and connected to a computer system.How to scan artwork with a flatbed scanner Before you start The curved drum keeps the film to light source distance constant, and avoids problems with reflections. The light and photocell then move a fraction parallel to the axis of the drum for the next line to be scanned. As the drum rotates, it scans every point on a circle around it. The light source is in the middle of the drum and the photocell outside. The drums used are typically a metre or so long, and a number of images are scanned at the same time, each negative being held on a small part of the drum’s surface. These are used by pro labs to scan your film, so it is hardly surprising that a high-resolution scan can cost £25 to £50 a time.
Generally, drum scanners are of an impressive size and correspondingly expensive, costing around as much as a car or a small house. Photo by /anyaberkut Professional drum scanning
