In fact if you read some books about the implications of quantum theory (wanky, I know!!) you will find that most everything seems to be quantized.........or divided up into little discrete units / bundles.
Even time and space as I understand it (although I rush to add that is not very much) is quantized at the limits of the Planck length (1.616252(81)×10−35 meter) which is the smallest distance about which anything can be known and Planck time ( 5.391 24(27) × 10−44 second) which is likewise for time. In other words analogue is "digital" at the extreme limits of what we can know and measure.
So maybe you should lay in the bath more often for such insights!
HMMMMMMMM is this why Einstein had such wrinkly skin??????????? I think we are on to something.

I'm saving aromatherapy for when hologram cameras are commercially available. And then I'll go and shoot with one nonetheless. Along with the "digital" and the "analog" ones.
An image is an image. The process is the process. And Socrates would claim nothing about knowing anything about them, only that they exist as much as you think they exist. And if he were a photography professor, he'd embrace all of it equally.

In some sense silver halide technology is "digital", in that it is Boolean. That is, the entire crystal of silver halide develops fully to a dark, opaque oxidized crystal, if it has been sensitized from having opportunistic electrons dislodged within the crystal lattice by photons. It takes as little as two photons with Kodak's newest film technology, yet the whole crystal develops out. What gives a continuous tone image in the emulsion is that there is a statistically significant distribution of crystal sizes within the emulsion; the small ones, with little surface area, only easily sensitized by the bright light of many photons, while the large crystal, with more surface area, can be sensitized by the weak light of few photons. The distribution of crystal sizes between these two extremes determine the response curve of the continuous tone image. Thus in such an emulsion there are only two types of crystals: those that have been sensitized and fully develop into an opaque crystal, and those that don't. These latter crystals are removed during the fixing process. Thus, film emulsion crystals display a binary, boolean logic.
Conversely, at the heart of a digital imaging chip is an analog device, called a photo-transistor. Such a device has within its gate structure an electric charge built up that is analagous to the amount of photons received. Only the post-readout circuitry is digital; the heart of digital chips are analog transistors.

If a technology permits the recording of images at a resolution equivalent to 1 pixel per atom, then it's logical that the same technology would permit the diplay of those images at 1 pixel per atom, creating images nowhere near the large size suggested in that link.
