Original negative is 4X5. Enlarged onto 8X10 half line litho film, contacted onto another 8X10. Positive and negative married together with a piece of tracing paper in between for edge effects and diffusion. Backlit in my prototype twinklebox (TM) with LED's.
I think this is my favourite of the set.... I'll have to stare for many days more to be entirely sure. Thank you for the detail of how you did this - again, something I'll need to think about some more to really take in. This whole series is simply wondrous!
With many details to leave out, perhaps I was not clear: the following four images are tight crops from the original transparencies (this one). It was the only way I could think of to convey certain aspects of the films. These are not five different pieces of film.
