Punking tourists is one use, but I can think of a ton more. This could and probably will be a big deal. I can see public locations using this so people can't take flash photos of specific things. People could use it at news conferences to deface the speaker in photos... only works when a flash is fired, but that's a lot of instances.

Red Army Faction cover tool??

gonna get shot carrying that thing around in some places.

But I can think of a million uses to get my product logo on Holloywood stars now...

Guy must be a technical genius

Able to get perfectly exposed overlays on a totally unknown EV using a 1970's vintage Minolta SRT100 series camera.
and what appears to be a modified Sunpack flash of the same vintage.

Projecting an image onto an image is nothing new but is usually done under fairly controlled circumstances
yet this thing isn't affected by ambient light ?

OK .... I'm thinking of an exposure between 4 seconds @ f/1.2 and 1/500 at f/64 - ISO unknown
and distance to subject unknown. What's the GN & flash duration of the Fulgurator ....

Damn - I gotta buy me some 30 year old Minoltas (if I can find a working one) and a Sunpak
with an external sensor. Oh yeah - better get one of those Kirk pistol grips too.

Looking at his "tech drawing" I have to say - Is it April 1st already ?

Just last night, I was telling my wife about it, and how great it would be for a haunted house tourist attraction. "And just over here, by this window, people sometimes report a ghost that appears only in photographs..."

I smell a rat.

What I want is a device that will make a politician inaudible when applied.
A bonus would be if it also worked on those stupid kids with their heavy base in their cars.

"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan

"This Fulgurator is the first prototype, and the most primitive. "It works, but it's not practical," he says. "In a few years time, huge companies will use it for @#$%&"..."

There you have it doubters. Huge companies. Using it. For... stuff.

I saw something about it using a "SmartSync" type slave trigger. Doable. Wein makes the triggers able to ignore fixed # of preflashes.

That thing is total crap...

Has nothing to do with using a smart sync

Here are the conditions under which this set up would work.

First as I said previously, projecting images via an optical system is nothing new.
I'm sure that the guy that invented the Magic Lantern discovered that he could project images
in a controlled ambient light environment and make an image appear in in a photographed scene.
There or tens of thousand bad examples from "art photographers" over the years that used
slides projected on subjects that were then photographed.

Thousands of studio photographers used the projected camera systems (Beattie) for years.
Shades of 1970 !

Just about every major lighting manufacturer offered a focus spot that could be adapted
or came with an accessory to do this. Balcar, Elinchrome, ProPhoto, Speedotron .... all of them.

This little device is using a flash mounted to the film gate to project an image through a telephoto lens.
No big deal. Shining a light source through a ground glass and projecting onto a subject is
one of the tricks of the trade for photographers trying to do critical framing and focus in near total darkness.
This trick saved my butt more than a few times. I even had an old fiber optic light source
from a surgical microscope that sent light through the eyepiece on a Nikon micro set up
so I could frame and focus high magnifications without looking through the camera.

The mere act of pushing light through a transparency is going to eat a couple stops of output
off of what already is a pretty meager light source (that on camera flash)

So OK - we got our image projector (whatever this thing is called) loaded with an image
and ready to project.

How do we determine exposure for the flash (and it's remote sensor - not even TTL let alone OTFP/TTL)
In order for you to get even close to projecting an image you would need to know the GN being used
and be able to overpower it (unlikely since you have already lost a couple stops with the transparency)
Throw in a couple of more variable like flash sync speed and flash duration and the odds
of doing this in a predictable, repeatable manner - not so great.

His two examples are pretty unimpressive - projected on to a black cell phone at close range
and the side of a building in the dark. I wonder how many tries that took.

It's something "cool" a guy did with some garage sale cameras but the next greatest thing ?

All the problems you pointed out can be overcome. I think it has major potential.

And you don't need to overpower the other flash, just get your own image in the picture. It may not show up perfectly every time, but it doesn't need to.
