Ce to see a Newman Sinclare camera in use. A friend and I used one for making 35mm films in the 1960's it was an ex BBC News reel camera. Clockwork driven, so intrinsically safe. The film was in a cassette which held 10o ft. We even manage to convert it to provide sync pulses for sound recording. First time I have seen one for over half a century. Happy days!

Gosh, back in the day, people used to be so much more curious. Just imagine a corporation creating such educational videos nowadays, when a TikToker’s attention span does not last more than 30 secs…

😂😂😂😂Too right mate. I’m 73 and still haven’t lost my curiosity. 👍🍻

@@Afro408 that’s what I appreciate about pre-internet generations (including mine) - people used to learn stuff and refer to books for knowledge, not like “I can always google it”

This is what happens to a world where everything happens by magic by pressing on a touch screen. People get everything they want without understanding what is happening mechanically electrically , optically , etc . Even worse: if we don't understand the science we cry conspiracy.

Heck, just here with recollection of Schlieren lines jumping out of my head jogged by watching the excellent Shell supersonic flight video. 40 years after encounters of supersonic lab experiments at Plymouth Poly!

This was neat. I always associated schlieren photography with supersonic applications; cool seeing all the other interesting and clever uses for it.

The Schlieren photography is amazing. I have always wondered about how they could possibly film supersonic shock waves and such. I learned something today. Thanks for the upload. 👍

A very impressive and educational film. Which audience was it made for?

@mitchelldakelman7006 9 ай бұрын

I have a 16mm print for US distribution with narration by American narrator Peter Thomas

Great! - what year was it made?

Looks like 1959 from the thumbnail

I understand the physics of this as that was my degree, but I've never studied any optics. Can someone with more knowledge please explain - why does the refracted light not appear shifted to the wrong position on the final image? Thanks.

@garysettles 8 ай бұрын

Schlieren optics involves a projector-like series of lenses or concave mirrors in which the the refracted light does indeed appear shifted in a focal plane related to the light source. In the case of this Shell film, that focal plane contains color filters. Later on, an image of the subject being photographed (person, airplane model, etc.) is formed, and in that image the refracted light is colored but no longer shifted out of position, because that image is sharply focused. That is the image that is recorded by the camera. In schlieren photography, the object under study is always sharply focused in the recorded schlieren image.
