Define the term 'framing' in composition.

Framing in composition refers to the technique of using elements within the scene to create a 'frame' around the subject, which directs the viewer's focus to the main area of interest. This approach enhances the visual impact of the photograph by guiding the viewer's eye and emphasizing the subject, effectively isolating it from the surrounding environment.

By strategically placing objects such as trees, windows, doorways, or even shadows around the subject, photographers can draw attention and create a sense of depth and context. This technique not only emphasizes what is important within the frame but also adds layers to the composition that can enhance storytelling.

The other options may touch on aspects of photography but do not encapsulate the specific meaning of 'framing' as it is used in compositional techniques. While using geometric shapes or arranging subjects involves composition, they do not focus on creating a visible boundary that highlights the subject. Setting a border during editing relates more to post-processing rather than the original compositional concept of framing.
