I am leaving this here for Farsight and others interested in pushing the technology forward into filming of higher dimensional entities.
We would need to improve out lenses that are more suited to seeing subtle energies / antimatter / aether, etc.
One scientist in this field who I've known about for the past few years is Ruggero Maria Santilli.
Among his many inventions one is called the Santilli Telescope, which has concave lenses and he claims it is able to see what he calls "Antimatter"
I highly recommend reading a bunch of his publications. I'll post a couple of relevent ones below:
Apparent Detection via New Telescopes with Concave Lenses of Otherwise Invisible Terrestrial Entities (ITE)
Thunder Energies Corporation, an optics, nuclear physics and energy company, claims to have detected "invisible entities" living in Earth's atmosphere... The corporation is run by controversial Harvard-educated Italian-American nuclear physicist Dr Ruggero Santilli... The nuclear physicist says the discovery was made using the Santilli Telescope he has developed to try to discover proof of theoretical anti-matter galaxies, anti-matter cosmic rays and anti-matter asteroids... It uses a concave lens - the opposite to the convex lenses of standard telescopes...
He said: "This is an exciting discovery. We do not know what these entities are, they’re completely invisible to our eyes, our binoculars, or traditional Galileo telescopes, but these objects are fully visible in cameras attached to our Santilli telescope..."
Santilli isodual theory of antimatter
I suggest farsight reaches out to him to see if you can collaborate and use one of his telescopes or get his help in designing a camera lens that could do a similar thing.
