Cinematography - Science topic
Cinematography (from Greek: κίνημα, kinema "movements" and γράφειν, graphein "to record") is the art or science of motion picture photography. It is the technique of movie photography, including both the shooting and development of the film.

If unexpectedly you still decided to read this, please note the following
`
Warning #1: please do and not use this discussion to advertise your own "breakthrough theories". For the latter, a better way is to submit a paper to a peer-reviewed journal (if you think you are right, of course;). I would be very grateful to you if you could consider this question in the context of the "usual'' General Relativity and take it with with a good criticism.
`
Warning #2: If you are a specialist in General Relativity, I am sure that the following would be trivial to you. But you might get some fun if you like Nolan's movies as much as I do.

The stunning idea of Nolan's Tenet - a time inversion machine - seems as far ahead from Interstellar (and as obscure) as Wells's The Time Machine was from Verne's novels. These wonderful examples of pure science fiction art and the ability to imagine the impossible, impresses us, despite all its logical gaps and inconsistencies with the physics of their times. Nevertheless, it could be justified, at least for science fiction purposes, using exactly the same concept of the Morris-Thorne wormhole as in Interstellar. Namely, one could consider the time-nonnorientable version of the Morris-Thorne wormhole.

By definition, a time non-orientable spacetime is a spacetime which admits no globally defined continuous families of future light cones. A simplest example of a such spacetime is the product of the infinite Möbius strip on R2 endowed with the Minkowski metric (here, the transverse (unbounded) coordinate on the Mobius strip is timelike).

The time-nonnorientable version of the Morris-Thorne wormhole is constructed in almost the same way as the usual one; the only difference is that we identify the points of "left" and "right" throats in the reversed order as in the Morris-Thorne's paper. We start with the usual R4 with the standard coordinates (t,x) and introduce the `time-reversed' coordinates (t'=-t,x'=x-x_0), where x_0 is sufficiently large. Then we remove the cylinders
П:={q | |x(q)|<r_0} and П':={q | |x(q)|<r_0}
and endow their neighborhoods with the metrics gMT(x,t) and gMT(x',t'), respectively, where gMT is the Morris-Thorne wormhole metric. Finally, we glue the boundaries of П and П' (`wormhole throats') to each other in the ``wrong'' (time-reversed) order, i.e., we identify the points q and q' if and only if
x(q)=x'(q'), |x(q)|=r_0, and t'(q')=t(q).
Since the Morris-Thorne metric gMT is asymptotically Minkowski, one can continue it far away from the throats to obtain the global metric (this should cause no more difficulties than the same for a usual wormhole).

The sequence of events e1,e2,e3 ,... on the one side of the throat which are ordered in ascending order of the time-like coordinate t=t1,t2,t3,... coincides with the sequence of the same events on the other side which are ordered in descending order of the same coordinate t=-t1,-t2,-t3,... . This means that the future light cone continuously translated along the closed curve passing through the throat becomes the past light cone.
Therefore, the observer that falls into the wormhole throat at the moment t0 emerges from the other throat at a moment -t0 and continues to move from the future to the past (with respect to the t-time) straight to the dinosaurs:)

The disappointing thing is that in such a spacetime there is not even usual electrodynamics (indeed, there is no globally defined Hodge star). I am sure that theoretical physicists will come up with many ways to "save" electrodynamics in the nonorientable case (e.g., considering the orientable double cover and the dynamics (CPT)-symmetric with respect to the isometric involution on it, which could be useful tool in other queestions as well such as studying the solvability of the Cauchy problem for the wave equation in such spacetimes), but I am not ready to go that far.
- - -
The question I address to the specialists in General Relativity is as follows: is there in the literature a time non-orientable spacetime such that removing some domain with compact closure from it leads to the orientable (and close to Minkowski one) spacetime (that would be more "realistic" and similar to what was in Tenet)? Maybe there are some no-go theorems for such spacetimes?

Heuristically, I suppose people consider films more successful the greater the return on investment(ROI). Stimuli: ”Successful films are often based on classics due to relatability and interest”(Ohnemus 2023). “My film career was and is perhaps successful despite my lack of technical skills. Arts have both applications and fundamentals”(Ohnemus 2023). Source:

Kirk Aanes must have been kind for Mulan (his ex) to speak well of him. "Just learned of the passing of Kirk Aanes. My condolences to his famiy and loved ones. He was a good soul. RIP, dear one"( https://twitter.com/MingNa/status/431264318701584384?s=19 ).

Good afternoon, dear researchers! I’m writing work about documenality of setting in modern series. I’m searching participants for my empiric research: 300 people for survey and 10 with knowledge of cinematography for interview. If you can help me or you want to be a part of it, write below your fb link or email.
Thank you for your attention!
For a research project I plan to conduct I want to analyse certain elements of the depiction of war in contemporary film, and I would like to have a look at existing research to see what methodologies are being used. First big research project, help would be greatly appreciated!
I been researching the democratic transition of Chile. My focus is on the cinematographic representation of everyday life and politics (State) during the democratic transition of Chile. I read the most important theories in the relation cinema and history, such as Pierre Sorlin, Robert Rosenstone, Roman Gubern, Marc Ferró, Gilles Deleuze, Christian Metz y José María Caparrós.
Does anyone know about general databases about Europen research projects (national and EU) ?
I'm looking for materials for a course on documentary and non-fiction film studies. I am open to any and all suggestions.
I am currently finishing up a study of Akira Kurosawa and I am hoping to move onto Yasujirō Ozu for my next project. I have never seen his films, but have read a great deal as to their compositional austerity and 'simple' narratives. I am hoping for a qualified answer as to where I should begin my viewing and why.
