Ever seen a sunrise in ultraviolet?

[Wolfgang Steiner]

[Wolfgang Steiner]

or what about some trees?

[Wolfgang Steiner]

all these shots were made with my fuji s3 uvir, the nikkor series e 35mm plus the baader u-flter.



and they are all handheld, with iso1600 of course

They really look like visible/IR than UV to me...

[Wolfgang Steiner]

This you should discuss with the Baader Planetarium Regit. I know now that this filter leak above 900nm, but if nobody helps to to get the Schott BG-40 filter it will be little bit difficult for me to do it and a better way. The exposure times are real long so I´ll guess that its about 60 to 70% IR and the rest is UV-A radiation. It must be in this way because this filter lets absolut no visible light pass. And because there is no color from above 900nm it must me from Ultraviolett.

Can you get this filter for me regit? I really appreciate if somebody would help me to locate this filter for me. (if possible 2mm thick)

Best regards

Wolfgang

I got my BG-40 from Akira Sakamoto, which he ordered from Shibuya-Optical. I think you've talked to him before, a really nice gentleman. He should be able to help out the purchase.

It does takes a bit of preparation and research if you want to do it properly. So, I would say continue and don't give up easily. Also, I notice that while you like landscape, you feel that good lenses for UV are normally too long for the application. To this, I would say that try to see things differently and it may be quite useful for you. While many people associate landscape with wideangle, many people also do landscape with telephoto, even up to 300-400mm.

Different focal length do different things to the perspectives of landscapes. Sometimes, if you do not wish to emphasise the foreground but would like to compress a scene, you'll have no choice but to use a telephoto. Here're a couple taken at 300mm effective (200mm actual)... So, it may be worth the try to frame with a 63 or 105 instead...
