Calming reflections....
Before photographing the Spitfire ashtray I racked my mind for ideas to calm shadows, ideally a light tent would be used but in absence of such equipment decided to use.... a white bin liner
With an assistant holding the huge diffuser/reflector I took the spitfire shot which has calmed reflections of Mosquito/Hornet (still undecided!) but flattened any interesting highlights and shadows from the Spitfire fuselage and wing area.
Below is the assistant and bin liner with end result.
