Because radiation from the Crab nebula is so energetic, the electrons that created it must have been travelling very close to the speed of light so close that the difference between the two speeds would bump up against Planck-scale graininess, and show up in the spectrum of the radiation.
Each rapidly taken image may be full of noise manifested as the unappealing static-like graininess.
For your correspondent, its pictures' graininess and a touch of "moiré" interference summons memories of late hours spent in basement terminal rooms in college, tapping away at white-on-black or green-on-black terminals, or watching fuzzy broadcast television on a tiny black-and-white set as a teenager.LCD and other display technologies have largely replaced CRTs.
The fineness of detail that a film can resolve depends not only on its graininess but also on the light scatter or irradiation within the emulsion (which tends to spread image details) and on the contrast with which the film reproduces fine detail.
To reduce the graininess that each generation of film adds to the original, concerns such as George Lucas Industrial Lightt and Magic produce their effects on 65-mm film.
The anomalies that arise could never be replicated on screen – magenta flower heads fizzing out of a murky, occluded patches of green, all with an organic graininess that the most skilled Photoshop user would find difficult to recreate.
Watching these super clear but super bland images, you yearn for the contrast and graininess in old fashioned 2D film.
A developer's main characteristics are activity, development speed, and effect on film gradation, graininess, and sharpness.
Of practical interest to the photographer are the graininess, resolving power, and contrast of a film.
This gives an appearance of graininess in big enlargements.
Just hours earlier he'd seen that the ground was undisturbed, yet he had gone to sleep and smelled the newly dug soil, felt its graininess beneath his fingernails, stared wide-eyed at the fallen gravestones.
