Lastolite Collapsible Background (4x5', Summer Foliage / City Lights). The crease-resistant, reversible fabric includes two distinctive looks, featuring the sense of background blur and reflected points of light called Bokeh, to give your portraits an "on-location" feel, as if you were shooting with a long telephoto lens and/or wide aperture. The rim tape is reinforced with more than 30 stitches per inch to make sure the fabric stays attached to the steel rim, which collapses to one-third of its original size after use, for easy transport or storage in the included circular zippered fabric bag.
