All credit to @fastchris for this shot who is the expert at shooting with circuit boards and double exposures
Shot earlier this year, in an undisclosed abandoned location near to where I live, we exposed firstly for the circuit board, and then after some planning and alignment exposed for my silhouette backlit with an orange flash and smoke. The alignment was to get the second exposure in line with the area where the CPU sits on the systemboard as no light comes through this point leaving it black, meaning a second exposure can be put over the top..
As always this is NOT a photoshop creation but was all created in camera
Equipment Nikon D600 16-85mm lens
Thanks very much for looking,
Kind Regards, Neil
