Akira: I sincerely hope you have more of those RTP 120 experiments to show
Bjørn, thanks for your kind words. Unfortunately, these two are the only decent result I could obtain while the film was available.
However, I might still have some UV image on another film (Fuji Natura). If I could dig one out, I would he happy to share here. Please bear in mind that I don't have proper means of reproducing the print, and I could not gurarantee the image quality.
It is nice to see UV captures on film, is it still possible or did they discontinue all of the films that were sensitive to UV?
Charlie, unfortunately again, the Fuji RTP or RTP II has long been discontinued. The Fuji ISO1600 negative film called "Natura" I briefly tested seems to be still in production. But perhaps it is only available in Japan.
You may want to try some B&W films that are also known to be sensitive to UV.
