Background Removal refers to the removal of the background or the backdrop of the picture wherein the object/objects are placed. While removing the background, the entire background or merely parts of the background we desire can be removed.

Previously, before the arrival of digital photography and the current accompanying technology, background removal was performed in a more laborious process.

It was once done in a darkroom under all of the proper temperature and ambient conditions. The film was watched closely while submerged in a working solution. By overexposing the film to the solution, the background was blurred and has a 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 commonly used raster graphics editors and digital photo editors will also work just as well. Most digital photo editors have plug-ins which can alter the background in different ways. Plug-ins are computer programs with highly particular functions. Most sophisticated photo editing programs use special purpose plug-ins and will perform background editing and removal based on special criteria.

Objects without backgrounds gain a new sense of versatility and purpose. They can be placed in a new backdrop, even in a new situational context. An example would be to remove the dining room backdrop of a flower vase and replace the background with that of a hotel lobby. The object can also be moved around in any way and you can change its alignment with the new background.

The interesting thing about an object without a background is that it retains all its properties like shape and size, but makes itself more flexible to individual usage.
