That made me smile!
When I was a trainee back in '60, we used to photograph airplane jet engines sitting on end in their factory locations. This work was mostly black/white, shot on 4x5 with slow film - I think it may have been R 10 plates, but it's too long ago to be certain.
The technique was simplicity itself: set the camera up on the tripod, stop the lens way down, and, with a handlamp, just paint the engine with light for about a minute or so; reciprocity failure meant it didn't matter a whole lot... Of course, the factory background was masked off with the ubiquitous roll of white paper which was intentionally further lost in printing. There's not much colour on the exterior of a jet engine anyway, so black/white was perfect. No hard PF 60 flash shadows to confuse the engineers for whom the work was done.
What a shame that digital sensors are so damned fast... that lovely and useful technique couldn't be applied very well today. It was pretty much impossible with normal films like TXP or FP3 too, and for the same reason.
