StudioLink Chroma Key Kit, 3 x 3 m, green, includes: An aluminum frame for quick assembly, a green Chroma Key cover for clip attachment, and a sturdy transport bag. The StudioLink Background System is a unique, modular background system for greenscreen effects in the studio or on location. Once assembled, multiple 3 x 3 m StudioLink backgrounds can be variably combined with the StudioLink Chroma Key Connection Kit (sold separately), for example, side by side, in a line, or in a curve up to a closed 360-degree circle. Additionally, the backgrounds can be arranged individually or side by side (using standard mounting devices) to create two layers of fabric. To connect the frames side by side, the optional StudioLink Connection Kit includes three mounting brackets to connect the aluminum frames and a bluescreen connection strip that attaches with clips to hide the frames and brackets. If two backgrounds are stacked or if a background is set up on a bluescreen floor, each clip on the background at the bottom edge is equipped with a fifteen-centimeter-wide sewn apron to conceal the aluminum frame and extend the bluescreen background to the floor or lower background. The StudioLink Chroma Key Connection Kit is sold separately. Available in green and blue. For those who want to switch between bluescreen and greenscreen backgrounds, the covers are also available individually.
