So you put a lens in front of your flash to focus the light. Seems like a better solution than a snoot.

He used to blast symobls into other peoples pictures at big events.

I constructed my own from an old T90 (broken shutter) in front of a Metz 45er.

Have to dig it out some time.


Yep, exactly, done by a descendant of our former chanceler Bismarck, he even patented that and I really wonder
if that is not in violation of his patent rights! http://juliusvonbismarck.com/bank/index.php?/projects/fulgurator-idee/

There is a discussion here about it and the Fulgurator is already being mentioned in here
- but no response of the maker who more than happily discusses other aspects of it....hmmm

I'd never heard of a Fulgurator. I like the idea, I admit, of projecting other things onto a scene. I had thought of it simply for making highly focused and directly point-light placement.

Its good to see a product around that allows you to use existing lenses, flashes rather than an all-in-one that limits creativity.

I invented and patented a product for dentistry that use commonly available disposables, was a cheap to make and was infinitely adjustable and cost less than 60. Other companies jumped on the bandwagon and put out their own (quite different) versions that used special disposables and were only suitable for their own product. And cost 500. They sold - mine didnt.

For this reason I hope this will be a popular product and I wish the guy luck with it.

Although I'll probably make my own version. A cheap enlarger lens ought to be suitable.

This is what is called an optical spotlight. I began using a studio strobe version in 1983. Not a new idea.

It could be argued the intent is different, as is the hardware shown on the Fulgurator.
Fulgurator is (rather cool, in my opinion) designed to stealthily imprint a light pattern on the work of others. The Blaster is entirely designed to be a deliberate part of the taken scene.
I actually quite fancy making a Fulgurator and spoiling the work of paps, sometime.

Got a response from teh maker of Lightblaster:

Hi Dr. Schmitt,
Thanks for asking. Without getting into any patent legalize, the gist of it is that the Light Blaster is a completely different invention and does not infringe on the one from Julius.

all my best,

I don't see much difference, but I'm no patent lawyer, just an engineer Wink

Metz produced a Televorsatz which I own and use with my 45 flash,produces excellent results.

That's interesting. Vivitar made a similar device for the 283 and 285. I got one for my 283, tested it with a flash meter. It turned out to cut off the edges of the flash, didn't increase the intensity at the center. So I got a 12" focal length fresnel and built bracketry to hold it and a 283. The result was much better, narrow beam with GN (ISO 100, feet) around 300. The assembly was very cumbersome and I hardly used it.
