Learn Digital Photography …background Removal
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.
Previously, before the arrival of digital photography and the current accompanying technology, background removal was performed in a more laborious 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 with any digital photo editing software like GNU Image Manipulation Program, or GIMP. GIMP is a special type of graphics editing application that is able to support some kinds of object-oriented (or vector) graphics.
It is not necessary that the digital photo editing software used for background removal be able to support all types of object-oriented graphics. The advantage in using GIMP of course, is that it enables easy vector to raster conversion.
Other widely used raster graphics editors and digital photo editors will also work well. Most digital photo editors are equipped with a number of plug-ins which can adjust the background in various ways. Plug-ins are computer programs with specifically dedicated purposes. Most sophisticated photo editing programs use special purpose plug-ins and will execute background editing and removal based on different 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.
