testing lighting setup for a project... works out having 3000 watts of tungsten lighting in a small room is not so smart unless you want to roast like a supermarket rotisserie chicken....
lesson learned low heat (Compact fluorescent) lighting rig now acquired.
next step .. a macro lens or close up tubes for the RB ( only Mamiya lens I have that can focus within the confines of the small space is the 50mm ultra wide angle hence the perspective distortion)
