Collapsible background

On a spring

— a studio background on a spring is a framed canvas that is mounted on a wall or hung on a stand. Most often, the frame is collapsible, which makes it easy to store and transport the background. The canvas in the frame is used for work on the road, where there is no opportunity or time to install a stationary background. Spring-loaded canvases work well for portraits, but they can also be used for close-ups of subject matter.
