The Lastolite (by Manfrotto) pop-up screens are 1.5 x 1.8m and give you a simple and effective background solution in one easy-to-carry bag.
Available as :
Chromakey green (also available in size 1.8 x 2.1m)
They all collapse into bag less than a third of it's original size, making it easy to carry and quick to rig.
Recommend hiring with background support kit (2x Lighting Stands and Collapsable Crossbar) to allow you to easily rig and adjust the height as required.
We're happy to advise on lights for these, if required, also - just let us know a few details about your shoot and we can give you the options.
