VueScan makes it easy to profile a scanner as long as you have an IT8 target (also called a Q60 target) and the data file that goes with the target. Then you compare the what the scanner says it is to what we know it is to see just what sort of adjustment is required to accurately capture that particular hue. And your freshly picked lemon may look a little green to your scanner.įortunately you don't have to live with this 'personality.' You can profile the scanner by simply letting it tell you what it sees when it scans a target with known, measured values. So your candy red car paint may look a little orange. The captures vary in their accuracy hue by hue. QuickScan Plus does none of these but VueScan does them all.Įvery scanner captures a limited range of color values we call a gamut. The three most important are profiling, multiexposure and providing emulsion profiles.

There are, alternately, some things software can do that dramatically enhance the scans. It can take an hour to scan a roll of film and two more hours to spot everything. So our general rule is to scan without defect removal and spend time spotting important images in the collection. It tends, however, to make the image soft. Some software does promise to handle defect removal without requiring an infrared channel. But it can be a time saver on color negatives.

That approach rules out doing defect removal on emulsions that are not smooth like black-and-white film or Kodachrome slides. It does this by reading an infrared scan of the film that shows physical abnormalities.

Commercially processed color negative film with defects at 100 percent.ĭefect removal involves detecting scratches and dust on the film and removing them by filling them in with neighboring data.
