Final answer:
Fringing or matting refers to the difficult-to-remove part of a background that can show up as a distracting halo around the subject of a photograph; it can be minimized by zooming in on the subject.
Step-by-step explanation:
The part of the background that is difficult to remove and is often referred to as fringing or matting can cause distractions in a photograph. In photography, fringing or matting effects can appear around the edges of a subject and are seen as an outline or halo that can be difficult to remove, especially when the background contains complex patterns or colors.
One effective way to reduce such distractions, such as fringing or matting, is to zoom in on the subject. This technique helps to minimize the area around the subject, thus reducing the potential for a busy or distracting background.
