The key element is only just in view, which is a Pringles tube mounted on the cameras lens and can be seen at the base of the pic.
The rest is fairly simple too. A piece of blue paper folded accordion like to create the background and provide the colour. The Pringles tube is just to help keep it upright, useful things, LOL.
Behind that a Yongnuo LED video light for the illumination.
The small 3inch high figure is stood on a plastic box to raise him to the right level.
Thats about all there is to it, quick and easy to set up for something a little different.
