- Wet Mounting. Before the drumming process starts, the image or negative is wet mounted. The film or photos can have many scratches, creases, dust, or other particles on the surface which may destroy the final effects of the scanned picture.
- Sharpness. Drum scanner can create very sharp images out of a very small piece of film. They can resolve the grain at such a high level and produce an overall sharp image.
- Tontonalityality Improvement. An important benefit of drum scanners is its tonality improvement. Drum scanner is capable of achieving better tonality due to its nature of scan.
Sep 8, 2015 · Drum scanners use each of the red, green, and blue photo multiplier tubes to scan the image pixel by pixel. Drum scanning is slower but a lot more precise reading the film point-by-point when compared to a CCD scanner that scans an image much like taking it with a digital camera.
