Suggestive photo, I like it., I consider it a good technical photograph.
I would just shoot with a shot a little wider, the extremes of the image that touch the edges of the presentation format are not in my opinion pleasing. Foto suggestiva, a me piace., la ritengo una buona fotografia tecnica.
L'avrei solo scatta con una inquadratura un pochino più larga, gli estremi dell'immagine che toccano i bordi del formato di presentazione non sono a mio avviso gradevoli. |

The problem is that in this case flat slides were used in contact with the subject. To get more details I used a larger leaf to increase the corona effect and better distribute the high voltage electric field.
Keep in mind that I made them in the years 70 and I cared more about the scientigic aspect than the framing as I do for photos I shoot with the camera.
Thank you for your interest.
Hello Il problema è che in questo caso sono state usate pellicole piane diapositive poste a contatto del soggetto.Per avere maggiori dettagli ho usato una foglia più grande per aumentare l'effetto corona e distribuire meglio il campo elettrico ad alta tensione.
Tieni presente che le ho fatte negli anni 70 ed ho curato più l'aspetto scientifico che l'inquadratura come faccio per le foto che scatto con la fotocamera.
Grazie per l'interesse.

Congratulations Bruno, you got a very good result, I had tried to use this technique many years ago with results very far from your.... :-(
A greeting
Paul Complimenti Bruno, hai ottenuto un ottimo risultato, anch'io avevo tentato di utilizzare questa tecnica molti anni fa con esiti molto lontani dai tuoi....
Un saluto

It is a problem of choice of voltage and frequency and also of waveform.
I used a voltage of about 20,000 V sinusoidal wave and frequency around 10khz.
In This way the current passes outside the object to be photographed producing a beautiful corona effect.
photos were made in the physics laboratory of the University of Genoa of which I was a student in 1970.
È un problema di scelta di tensione e frequenza ed anche di forma d'onda.
Io ho usato una tensione di circa 20.000 V onda sinusoidale e frequenza intorno ai 10kHz.
In questo modo la corrente passa all' esterno dell' oggetto da fotografare producendo un bellissimo effetto corona.
Le foto sono state fatte nel laboratorio di Fisica dell' Università di Genova di cui ero studente nel 1970.
Grazie per la visita Paolo
