hello Antonino , i just start to read your blog, and i´m impress, i´ve been working in the same theme here in Chile, at the CNCR http://www.cncr.cl/.
I have a D90 UV VIS IR from Max Max, a vintage vidicon IR analog camera and a set of Peca forensic filter.
I really like, if you want, show you part of me work.
Best Regards
Carolina
Hi carolina, sure! U r welcome!
Hi Antonio,
Just looking at the filters you use and was wondering why for UVF you switched from B+W 486 to B+W 420 that allows VIS and IR so that you have to block IR with the additional X-Nite CC1. Was B+W 486 not good enough for UVF and VIS photography?
Thanks
Damian
Hola Damian,
B+W 486 is not good enough to stop uv reflected so we need the B+W 420. ciao
Hello Antonio,
I am a photographer from South Korea. Recently, I got interest in uv photography,
I am researching the way to take portraits by using uv light source with dslr camera.
My plan is to getting rid of lowpass filter in front of CCD, and use lens for analogue film enlarger. I would like to take only uv spectrum without visible and IR.
Could you recommend me about spectrum cutting filter in this situation and also about the plan for portrait?
Best regards
Jongwoo
Hola Jongwoo!
nice to meet you! Briefly:
1. yes, you need to convert your camera to “full spectrum”, get rid of the UV/IR stopping filter.
2. You have to use two filters together the X-Nite CC1 (stop IR) and the B+W 403 (stop VIS). And then you are good to go. As far as you photograph in the 360-400 nm UV region you can use a normal lens. I recommend old ones since they are less likely to have heavy coating that would stop the UV. Enjoy!
Hello, Your website and published paper have been thoroughly illuminating and we thank you greatly for sharing your experiences with the interested community. We are doing a similar project and have run into the IR leak snag for UVR. Have you tried the Baader Venus II? It’s a bit on the pricy side for a filter but the graph shows no IR leak:

Hi, thanks for the appreciation of CHSOS blog and glad it has been helpful to you. Send me more info about your project and where you are located. This filter you suggest seems very nice but I didn’t try it. Let me know if you have a chance to buy and test it. Cheers
Antonino
