Many people have JPEG or GIF files. They all have backgrounds, and as such may require modifications. Both are good image formats to work with, even for a specialist. If there are graphics in the image and the montage needs to be changed or modified, an expert is required. And it is not only the background that is removed. When the image is edited, there may be a loss of color or contrast. It will have to be adjusted. If a new element is added or an edit is made with few images, then the background needs to be really changed. The alteration is mixed with the original, otherwise it will look terrible to the eyes.
Background Removal Sample
While a basic editor may simply loosen the montage and replace it, a specialist will do something else. An adjustment layer or parts of the image will be masked. With a keen attention to detail, he can check if a retouch should be done. A background removal specialist is always working on advanced imaging systems. He is able to add special effects because they can make the images better. His method of improvement will be subtler, cleaner and definitely more professional.
