You can remove the background or backdrop behind an object in a picture with a process called background removal. This process can remove the background in its entirety, or you can choose sections or parts that you desire from a backdrop to be removed.
The advent of digital photography and its accompanying technologies has made background removal an easy editing fix. Before such capabilities were available, background removal of a photograph was a more difficult process.
It was performed in a darkroom with the necessary ambient conditions including proper room temperature. The film was submerged in working solution and was monitored constantly. Overexposure of the film to the solution could result in an increase in background blur and decrease in resolution.
Today, background removal is possible using any digital photo editing software like Image Manipulation Program, GNU, or GIMP. GIMP is a special kind of graphics editing program able to support some types of object-based (or vector) graphics.
The digital editing software you use for background removal does not have to be able to support all kinds of object-oriented graphics. GIMP however offers the advantage of easy vector to raster conversion.
Other popularly used raster graphics editors and digital photo editors will also work just fine. Most digital photo editors have a number of plug-ins which can modify the background in different ways. Plug-ins are computer programs with highly specific purposes. Most sophisticated photo editing programs use special purpose plug-ins and will perform background editing and removal based on different criteria.
Objects without backgrounds can be used in several different ways. They can be placed in a new backdrop and in different situational contexts. For eg.: a couch in furniture showroom could have the furniture showroom replaced with an office. The object can be moved around any which way and it's alignment w.r.t the new background can also be changed.
An object can gain a new sense of purpose without changing itself at all. It retains all of its properties like shape and size but becomes moldable to individual usage.
