What do we see when we look at images at 100%

Don't sit on the fence and be a politician, was it anymore real or not? what about when we used to say that the film had grain like golf balls, think of that Agfa 1000ASA slide film, now all we had was one big grain that was an average of many rays of light and gave that soft look, then there is infra red film, was that a true representation? I have my answers but reality is that digital at the top level is recording in such fine detail that it captures light at very many more sites than film ever did at equivalent ISO

large grains, like large sensor sites collect more photons, pretty obvious really.
Infra red is just what we call some particular long electro-magnetic waves of light. . Infrared produces the true representation for that particular wave length.
Extreme fine grain film had much the same size grains as a high count pixel sensor has, so no difference there.
The problem with minute pixel sises and grains is that they capture few photons. and noise become an issue.

The main advantage of Grains as against pixels, is that they are totally randomly placed. they are also tend to random shapes and sizes and do not have supporting structure between them.
However there is no doubt that the quality most people get from their digital cameras is far higher than they ever got fro film.

Everything is an approximation of reality, including what the brain does with the electrical impulses from the retina.

No one has ever seen reality, only their CNS interpretation of it.

Before film photography there wasn't any grain. There were lines and splodges of paint and pencil.

Ah but, it’s covered in @Pound Coin’s post but easy to miss.
Photography is both the art and science of creating images with light.
Scientifically, all we’re doing is capturing photons in our camera, but artistically we’re choosing which photons and even occasionally creating our own photons to capture.
Are we really capturing photons?
Does that mean the sensor will clog up with photons after a while?
