I think this says it all.

I like that one, too.

this was drawn by Everett Raymond Kinstler an illustrator and comic artist who became one of the top Portrait Artists in America. Painting celebrities and people of power. Including every president from Carter to Trump.

Ray passed away last year at the age of 94.

His work was too good for comics. He used fine lines that reproduced poorly in that medium. His best work would be found on the inside front cover, where it would be printed on gloss stock.

He wanted to be a great illustrator like James M. Flagg or Gibson. He figured out in the 50s that the day of the great illustrator was vanishing and moved to portraiture. And became great. He adopted the style of artists like Sargent and Chase.
Here is a nice one of his dear friend Tony Bennett.

1) Early film was not too sensitive. And what with 2) a moving figure, 3) in veils, 4) indoors, 5) in changing weather conditions, a dancing figure did not appear on the film. But immobile architecture did.

What was 6) a dancing girl doing there? Many ancient temples were in part filled with prostitutes, sex workers. 7) Though some didn't want this to be known.

Often you had to open the shutter, and expose the photographic material to light for some time. Even for more than a full minute. As in modern "time exposures."

And so if anything moved in that period, it blurred, faded. Or if it moved pretty fast? It would never appear in the negatives or final pictures at all.

...are just cases of people not knowing how cameras work.

Most religious ideas in fact, may come about from people failing to more precisely understand complicated things in nature, technology, psychology. As naturalistic theories tell us.

As far as the old film-based photography goes? Consider what you can get from a "double exposure." If you took 1) a picture of a temple in India, 2) and then forgot to advance the film, you might shoot a picture of your Aunt Mildred on top of the temple picture. And get a print of a ghostly Mildred, hovering above the temple.
