In this page we examine the MTF of scanners and sharpening algorithms, and we address the question, "What scanner resolution (pixels per inch or dpi) is required for a digital print to appear sharper than a conventional darkroom print?"
Although digital cameras are the most popular devices used to capture photos, scanners are still widely used to scan slides, negatives, and prints. You can do this yourself if you have a scanner, or you can have them scanned onto a CD disc or floppy at your local photofinisher or lab.
The modern digital camera is not the only photographic tool at our creative disposal. The scanner can also be used as a camera for transforming photos into digital files or three dimensional objects into photos.
