The Tupolev Tu-4, a Soviet bomber built by reverse engineering captured Boeing B-29 Superfortresses. Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight ...

Since extension tubes do not have optics, they do not affect the optical quality of a lens. Due to their function, there are other effects: decrease of light; shallower depth of field; and loss of ability to focus at infinity. The longer the extension tube, the closer the lens can focus.
One of the contentious issues surrounding the use of proprietary formats is the control of the files. [citation needed] If the information is stored in a way which the user's software provider tries to keep secret, the user may store the information by virtue of having generated it, but they have no way to retrieve it except by using a version of the original software which produced the file.
