This is a Photoflex fast and easy reversible chroma key green/blue backdrop that you can take anywhere. It is flexible, and compact - great when shooting for digital composites or drop outs. Some examples: senior protraits, catalog products, or any photos where you want to control the background. Strong steel frames are double-rivited, not spot-welded like most collapsible backgrounds.
Also available in blue only (BG5X7BDISC). Comes in a handy zippered carry bag. It folds to about 34" diameter.
Add a light stand, and disc holder for control and support of this collapsible background.
