7 Favorite Stanley Kubrick Films

In a medical x-ray machine the body casts a shadow on an x-ray sensitive plate. X-ray lenses are generally used to collimate or focus an x-ray beam, not to create an image.

X-ray lenses have been repurposed for photography for decades.  The extremely large apertures lead to extraordinarily shallow depth of field.  Similarly, projector lenses and enlarging lenses have been repurposed for photography for decades.  But then you already knew that.  Or not.  The interwebs has loads of info about these things.  I've not bothered with it because I don't want to fiddle with buying or building the right focusing helicoids.

Yes, I've used enlarging lenses (in my enlarger) and I had a projection lens that I was thinking I might use to build a camera obscure (never got around to it). But an x-ray lens is a component in a scientific or medical instrument. Such a lens is not typically used to create an x-ray image, and wouldn't work with visible light. I've come across some visible light lenses which are marketed as "x-ray" lenses. Maybe that's what you mean.

No, I mean X-ray lenses.  Again, the interwebs is filled with information on the subject.  Obviously, you did not look for any before posting.  That's fine.

Perhaps you could supply one such "interweb" link to clarify?

I suspect you are capable of using Google.

I can use google, but I'm genuinely curious about what you are referring to.

Search for various German optical companies and see what you find.  I don't provide links on demand.

For me the R Strauss and J Strauss II pieces in 2001: A Space Odyssey did not work well. I think there are too many other associations with those pieces that don't have anything to do with the film. To me they feel like something taken from somewhere else and slapped onto this movie. In general I think music and sounds created specifically for a film are ideal. There are some exceptions where I think excerpts work. I think the Ligeti used in the movie was effective.

These days the choice of the Blue Danube to accompany the 'cosmic' dance of the spacecrafts may seem a bit cliched, but back then, for me at least, it was a brilliant and unexpected masterstroke, and it introduced a sense of humour and irony into proceedings, which still makes me smile as I think about it now.
The Also Sprach Zarathustra I feel less strongly about, but thought it worked fine.
