    Electricity and Film- now this is awesome

    The artist Hiroshi Sugimoto is applying 400,000 volts of electricity to film.

    The results are very interesting.

    If you like that then search for what high voltage does to titanium.

    ^^^ I'm looking but so far I've only located commercial sites... nothing instructional.

    EDIT: Here are a couple of sites showing rainbow anodization. all I can find are commercially available products... sorry. The thing I saw years ago involved high voltage electrodes dragged across the surface of titanium sheet metal resulting in some pretty wild colorful shapes with lightening-like spark patterns. But I can't find anything on that process now.

    And in a similar vein, . Big epilepsy warning on that one though.

    So, this guy had a dry lab and got a lot of static electricity, right?

    Wow, a hero.

    It is common for static discharge to reach 500,000 - 1,000,000 V with low amperage and the results enlarged will look like what you see. I hate to inject a note of reality here, but there is nothing new. You can generate these easily in your dry darkroom.

    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.
