Using a computer and a photo editor between the scanning and the printing process provides the artist with a greater level of control, allowing, at a minimum, the ability to "clean" the image by removing specks and other imperfections in the capture. With the increased availability and affordability of flatbed color scanners in the 1990s ...
This makes scanning traditional black-and-white film more difficult and requires a scanner with at least a 3.6d dynamic range, but also a Dmax between 4.0d to 5.0d. High-end (photo lab) flatbed scanners can reach a dynamic range of 3.7, and Dmax around 4.0d. Dedicated film scanners [66] have a dynamic range between 3.0d–4.0d. [65]
(Photo taken under inactinic light.) A stepper or wafer stepper is a device used in the manufacture of integrated circuits (ICs). It is an essential part of the process of photolithography , which creates millions of microscopic circuit elements on the surface of silicon wafers out of which chips are made.
Reverse automatic document feeder A scanner with a duplexing automatic document feeder A Konica Minolta photocopier with an automatic document feeder in use. In multifunction or all-in-one printers, fax machines, photocopiers and scanners, an automatic document feeder or ADF is a feature which takes several pages and feeds the paper one page at a time into a scanner or copier, [1] allowing the ...

In 1826 Niepce was the first to develop a photo which used lights to reproduce images, the advancement of photography has drastically increased over the years. Everyone is now a photographer in their own way, whereas during the early 1800s and 1900s the expense of lasting photos was highly valued and appreciated by consumers and producers.
The difference between steppers and scanners is that, during exposure, a scanner moves the photomask and the wafer simultaneously, while a stepper only moves the wafer. Contact, proximity and projection Mask aligners preceded steppers [39] [40] and do not move the photomask nor the wafer during exposure and use masks that cover the entire wafer.
If the difference is greater than a user-specified threshold setting, the images are (in effect) subtracted. Digital unsharp masking is a flexible and powerful way to increase sharpness, especially in scanned images. Unfortunately, it may create unwanted conspicuous edge effects or increase image noise.
