Thanks for your quick reply!
We will not be compositing any images inside the armour or compositing the armour over any background video. It needs to look almost as though a solid black mannequin is wearing the armour rather than a person.
The shoot will be taking place inside a completely white, boxed set and so the background behind the armour will be white. However there will be occasions where another actor will walk in front of the armour.
We do not have access to 3D software I’m afraid.
