1917 tunnel flashlights (1 reply)
I was reading in ASC Mag that you mentioned your gaffer supplemented the flashlights with LED's. Did he/you create your own kind of fresnel or spot lens and then you further augmented the edges? It definitely looks like you were able to create a very direct beam in the film. Almost like a mini xenon beam when it goes through the smoke/dust at points.
We had the prop department manufacture slightly larger 'lenses' for the front of the flashlights that exactly matched the original design. Then we sand blasted the edges of the glass so that the small LED we rigged in the back gave a light beam with a hot spot in the center and soft edges. The distance of the LED from the glass and the size of the glass 'lens' was key to the look of the beam. It took us quite a few experiments, which included shooting a test in a mocked up tunnel, before we settled on the final look of the beam.
