Hmmm...I'm going to go take a look at that gallery! Thanks for posting.

Mike, any good references for that?

^^^ 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.

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.

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... :confused: 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.

I beg to differ PE!

IMHO, ALL photography is at least a little bit magic

I think I'm loosing something big here. What is a dry lab?

I actually hate when this happens when I double load 120 film, which I have to remove atleast one piece of tape to adhere to next roll to fit on one spool. If I see sparks I go super slow and usually breathe a bit of moist air onto the area.

Ah, yes, that's a common phenomenon, with cameras with manual rewind knob it is advised to rewind the film slowly to avoid static electricity discharges, which will be visible in the images. Nihil novi sub sole.
