When choosing a suitable scanner, these terms play a major role. This information can be used to digitally recreate the image. To put it simply, scanning gives you various information about the slide.

There are various methods for doing this, which we will explain below. With an appropriate slide scanner, such effects can be eliminated during the scan. Modern methods of dust and scratch correction offer particular advantages. A high level of detail is therefore crucial to get high quality results. In addition to the correspondingly high resolution (or point density or dpi), essential criteria for good scanners are a high color depth. However, such a high-quality result can rarely be achieved with this as with a high optical resolution. With this method, slides with a lower resolution can be scanned and then projected. For home use, they have been replaced by flatbeds and transparency scanners.Īnother point is interpolation.

Today, drum scanners are mainly represented in the professional area of prepress technology. Higher values can only be achieved with so-called drum scanners. Semi-professional devices achieve up to 7200 dpi. (The definition of the term dpi can be found in the category guide.) The maximum resolution for devices from the amateur sector is around 46oo dpi. By scanning the object line by line, the information is processed and different brightness values and colors are converted into signals pixel by pixel.ĭepending on the resolution of the scan, large amounts of data are generated. The digitization of slides is similar to the scanning process in a typical flatbed or photo scanner, which specializes in digitizing photos.
