Wow beautiful accomplishment!! May I know the equipment you did it with? Thank you Marzio Wow bellissima realizzazione!!! Posso sapere l'attrezzatura con cui l'hai fatta? Grazie Marzio |

Thanks for the comments!
@MarsCr use 2 UV flashlights at 365nm, for the rest standard equipment (tripod, Canon 6D and Sigma 105 lens as in description); I think you and I talked about it some time ago... We're probably the only two interested in this genre! Grazie dei commenti!
@MarsCr utilizzo 2 torce UV a 365nm, per il resto attrezzatura standard (cavalletto, canon 6d e obiettivo sigma 105 come in descrizione); credo io e te ne avessimo parlato anche qualche tempo fa...probabilmente siamo gli unici due interessati a questo genere! |

Thank you!! So you don't use filters? Neither on a lens nor on a flashlight? If so, it seems that you have found a good compromise to avoid infiltration from residual UV.
It's a shame there aren't more people who are interested in this particular world. Ti ringrazio!! Quindi non usi filtri? Né su obiettivo né su torcia? Se è così sembra che tu abbia trovato un buon compromesso per evitare infiltrazioni da UV residuo.
Peccato non ci siano più persone a cui interessa questo particolare mondo. |

@MarsCr actually the torches (I use 2 of them) already have a UV pass filter installed in front of the LED and that's why they emit "almost pure" UV; Regarding the camera, in the past I have used a UV cut filter mounted on the lens but I have not detected any benefit in terms of result, as the sensor of all cameras already provides for the cutting of lengths outside the visible. @MarsCr in realtà le torce (ne uso 2) hanno già un filtro UV pass installato davanti al led ed è per questo che emettono UV "quasi puri"; riguardo la camera, in passato ho utilizzato un filtro UV cut montato sull'obiettivo ma non ho rilevato alcun beneficio in termini di risultato, in quanto il sensore di tutte le fotocamere già prevede il taglio delle lunghezze al di fuori del visibile. |

Hi Ricric,
but... if you mount a UV cut, it cuts off your UVs, as the name implies...
if, on the other hand, you put for example a Baader U-Filter (which allows only 320-380nm to pass through) on a camera with all the filters removed and illuminate with 2 UV flashlights at 365nm (which you have and are in the range of the filter) you are on horseback...
greetings :-) ,
Mick Ciao Ricric,
ma...se monti un UV cut, ti taglia via gli UV, come dice il nome...
se invece metti per es. un Baader U-Filter (che lascia passare solo 320-380nm) su una fotocamera con tutti i filtri rimossi ed illumini con 2 torce UV a 365nm (che hai e sono nel range del filtro) sei a cavallo...
un saluto  ,
Mick |

Hi @Mick, actually the sense of the UV cut on the lens is precisely to cut the UV;
This type of photography is based on the principle that some materials, hit by ultraviolet rays, emit visible light that hits the sensor and generates the image, in this specific case we are talking about a flower pot; the UV cut
on the lens could therefore help to exclude any UV returns and to select only the visible; I repeat, however, that this precaution is completely useless as the sensors of all cameras are already protected by UV/IR cut filters.
For better understanding, the acronym UVIVF stands for UltraViolet Induced Visible Fluorescence;
It's an interesting phenomenon...
Greetings
Ciao @Mick, in realtà il senso dell'UV cut sull'obiettivo è proprio quello di tagliare gli UV;
questo tipo di fotografia si basa sul principio che alcuni materiali, investiti da ultravioletti, emettono luce visibile che colpisce il sensore e genera l'immagine, nel caso specifico parliamo di un vasetto di fiori;
l'UV cut sull'obiettivo potrebbe pertanto contribuire ad escludere eventuali ritorni UV e a selezionare solo il visibile; ribadisco però che questa accortezza risulta del tutto inutile in quanto i sensori di tutte le fotocamere sono già protetti da filtri UV/IR cut.
Per maggior comprensione, l'acronimo UVIVF sta, appunto, per UltraViolet Induced Visible Fluorescence (Fluorescenza Visibile Indotta da UltraVioletti);
E' un fenomeno interessante...
Un saluto

I understand Ricric, it's the electromagnetic waves bordering the uv but visible, I want to try it too... Thank you, greetings ;-) Capisco Ricric, sono le onde elettromagnetiche confinanti con l'uv ma visibili, voglio provare anch'io...grazie, un saluto |
