The usual IR photography is based on near-IR energy, it's not quite the same as the night vision type IR devices, or the Sony see-through cameras. They work on a different spectrum.

Why does owning a Sony cam and IR filter make it illegal?

[bernards]

No guide to which Sony models work.

BTW. Where can you buy 1000 nm rated IR filters for $20 or $30? Those are probably the lower rating ones. Those high pass filter are very expensive. A Hoya one can cost you about $300.

Technically, Xray and IR are on opposite sides of the visible spectrum. So the Sony camera with the IR filter is not an X-ray camera.

The Sony camera has a night shot mode that is sensitive to IR. Our body emits IR that penetrates some types of clothing. Using a IR filter to filter out the visible spectum the camera then has the capability to see through clothings.

I think owning the equipment may not be illegal, since it was sold commercially, but using the equipment to take see-through photos without the subject's prior consent should be illegal.

Thanks for the layman explanation on how this see-thru feature works.

Your last paragraph should be addressed to ckiang though.
