    I was looking for a post like this (I know it's old). I have many question regarding those pictures: can this process be made with any kind of emulsion? I want to do something similar on a home made emulsion on canvas. Also. how can I generate a static discharge like that one? Can you guess a way of obtaining such results?

    Thank you very much, I hope someone answers.

    All emulsions are sensitive to the radiation emitted by lightning discharges such as static electricity. The density of the image formed is proportional to the speed of the emulsion.

    All you need is a dry lab and you begin to get such discharges. You can even generate them with scotch tape. Put some tape onto a piece of plastic, sit in the dark to adapt your eyes and then peel the tape off of the plastic. You will see bright flashes.

    The next experiment should be applying 400,000 V to the rear ends of Kodak management team

    With a Tesla Coil you can get millions of volts!

    I agree that Kodak might get moving with that applied to management.

    So you can with a Van de Graaff. But a Tesla coil does not produce static electricity; not that that matters for these purposes.

    It is the intense blast of UV along with the jagged path of static electricity across the film that makes pretty patterns.

    It is the million volts of lightning that gets management moving.

    Sorry I was unclear.

    I'm trying to work out what's more impressive, the beautiful images or the scientific explanations... Ohhh, photography.

    This is not "photography" because it does not involve light but "electrography" because it is electricity which forms the image on the electricity-sensitive film.

    I therefore think this discussion should be moved to the sister site EPUG (ElectroPhotography User Group) because it doesn't belong here

    By the way, ask a digital photographer if he can do that with his camera!

    This is "photography", pure and simple.

    The static discharge emits light just like lightning and just like lightning it can be imaged on film. Nothing magic.
