What describes the frame around an image?

The frame around an image is best described by the aspect ratio. The aspect ratio is a mathematical ratio that compares the width of an image to its height, indicating how the visual elements are proportioned within the frame. It plays a crucial role in determining how visuals are presented, affecting everything from composition to how the viewer perceives the image. Understanding aspect ratios is essential for various media formats, including film, television, and photography, as it influences how the final image appears to the audience.

The other choices touch on various aspects related to visual analysis but do not accurately capture the essence of what defines the frame around an image. For instance, while width and depth refer to dimensions, they do not address the critical relationship between width and height that aspect ratio does. Similarly, composition refers to how elements are arranged within the frame, and scale pertains to the size of those elements in relation to one another, but neither specifically defines the frame itself.
