This, of course, not quite that, but who knows, maybe the nature of the reflection from the same surface (living plants, for example) will also change???
Somehow in the beginning

we seminarile in Eskom triangle (the village Molebka Perm region) and met an interesting photographer. His camera was
quartz lens (standard Jupiter for shooting in ultraviolet rays), and instead of flash in mind something akin to it - with a thick quartz lens about
20cm in diameter (with lens hood), and this thing was cable with headphones. From his explanations (as I then understood and now remember

) the device worked as follows: in
the middle UV all objects reflect (emit) in different ways, including non-material entity. Lens collected ultraviolet rays at some
standard Converter, which, through electronic circuitry, the signal goes to a sound generator. We then tried to listen... Really
when you hover over different objects, trees, bushes and people, the tone in the headphones (and seem to volume) changed significantly. By the way, and when you scan a person's vertical
the tone is also very varied. A photographer, for example, easily figured out among us, Ivanovo in much fonyaschih (from regular dousing with cold water) throat chakra. Methods
photographing any "entity" was simple - the scanning space, and the appearance of anomalies (not due to a natural change in the subject
situation), just press the camera button. The photographer was showing us his photos (b & W), which really had something photographed, it is highly
unlike standartnye then common defects of photographic evidence (I speak as a professional technical photographer). Our "witch" has neprimenuli
to hang a few of these anomalies on the trees, which the photographer also took... Judging by the way they whispered and giggled, when printing photos the photographer
waiting for the "pleasant surprise".

The photographer claimed that he had collected this device according to the scheme published a few years ago in the journal Radio. For those who will look for it
it was in 1992.<
