Re: Where can I get this dress?
How funny, bareone!! The flash must be just the right frequency of light to go through that specific fabric. Now we really need to know where we can get that dress...anyone have any clues? I'd love to have a dress like that! And then what kind of fabric is it? Maybe other tops, etc. are made from the same fabric.
BTW...this would totally explain the innocent wearing of a very pretty dress, even to an event with your daughter.

Re: Where can I get this dress?
Absolutely funny, bareone! Love it. But I'm with you, Jeanette...I'm even more interested in the fabric in the photo. BUT WAIT!!! Bareone...what kind of fabric is your dress? Can you give us a description of your dress...where you got it, brand name, etc.? We don't have to wait to find out about the original photo...we have an expert right here!! So, bareone...if you don't mind, please give us the hot story and we'll all run out to the stores to get one!!

Re: Where can I get this dress?
It happened to John Kerry's daughter too. I guess you could say it's a well known effect. I wonder exactly how it works. It's probably not the frequency, because the frequency of light determines its color, and camera flashes, like most lights, are mixed color (white).
It might be simply the brightness, but you'd think sunlight would have had the same effect then. Maybe the angle is also important. That is, with a camera flash, the light source is very near the lens.
Sounds like something that needs scientific investigation.

Re: Where can I get this dress?
I wonder if the flash on these cameras is a strobe light, it might have something to do with the polarization of the light.
And even more, I wonder if the manufacturers of these garments are aware of this.

So, actually the myth of "glasses to see naked" really exists!

Re: Where can I get this dress?
OK, seeing as how I have taught Physics classes I'll point out a couple of things.
Possibility A: The frequency (color) of the light matters most: Many materials reflect some frequencies of light, absorb some, and transmit others, the transparent frequencies need not be near each other. So a dress that appears black absorbs most light and reflects a little other light at various frequencies across the spectrum, some very small bandwidths of light are transmitted. In full spectrum light (like sunlight) it appears opaque. But if the camera flash uses light at those same bandwidths and not the rest of the spectrum the dress appears transparent.
Possibility B: The polarization matters most. Imagine the light wave as a wavy line rather than a 3D wave like an ocean wave. The line has to be wiggling either up and down or left to right or something in between. Non-polarized light is made up of lots of waves wiggling in all different directions. Certain materials polarize the light by only letting one direction (like up and down) through. If the camera has a polarizing filter than is lined up in the same direction as the polarizing material of the dress, or the light from the flash is polarized the same way the dress will become transparent.
Either way luminosity (brightness) also comes into play as bright light makes it easier to see through translucent (semi-transparent) material, so the effect is most likely with professional photographers using high powered flashes and a variety of filters.
So to have this effect work the dress and the camera flash need to be matched up with each other, probably making the effect quite difficult to achieve on purpose, a dress that has this effect with certain cameras will not have it with all cameras and likewise a camera that has this effect on certain dresses will not have it with all dresses. If you wear undergarments made from the exact same material as the dress the camera will be able to see through them as well if it can see through the dress.
"Glasses to see naked" don't actually exist with current technology. The lenses in glasses can bend the light making it easier to focus, filter out certain colors, or polarize the light. So it would be theoretically possible to make glasses to see through a certain material, but they would only work for that one material. The technology to see through more kinds of material works by using light from a different part of the spectrum besides visible light and then converting it into a visible image. So X-rays see through clothing and flesh but not bone or metal. The modern scanners used in some airports see through clothing but not flesh, metal, plastic or leather using a different portion of the non-visible spectrum.
These devices are currently very large but could eventually be reduced to wearable size, as computers have been reduced from room-sized to pocket sized over the past 50 years. So you maybe be able to buy "glasses to see naked" on the black market 50 years from now.

Robert, I can't wait that long. I'll be dead or at least senile. 
First I had to give up every teen boys dream of being invisible in the girls locker room. Now you tell me this....it's almost too much to bear.

No, but airport x-ray machines do.http://newsmine.org/content.php?ol=security/bigbrother/airports/london-airport-xray-sees-through-clothes.txt
