| It's dangerous, trying to interpret black and white photos. Rolls-Royce reckon that satin black was the designated colour, except for marine engines, which were finished in cream. In those photos, the printer would only need to use a less contrasty paper, and the black turns to grey, with the plate, being flat matt, absorbing more light. Also, the areas, which are not reflecting the light straight back, towards the camera, e.g. the sump and rocker covers, are obviously black. Edgar |
