I've some associates who shoot large cabinetry/furniture that often has a lusterous/glossy finish. The wood is so deep in tone, that conventional lighting often produces too much glare and not enough wood grain visible in the shot. The softboxes need to have sheets of polarizing filter material taped across their face, on the outside. Of course, all the pieces need to be orientated is in the same direction. (Just make a bunch of witness marks or arrows on the roll before cutting it apart.) Then use a polarizer on your lens and adjust accordingly. Be advised, you loose many stops of light. That method takes all the highlight glare right out and produces deep saturated wood tone with lots of visible detail.
