We have to agree that all and every photo we see posted at internet is a bunch of pixels, ie, it is a digital photo. People sharing their originally film, plate, sheet, glas or paper pictures should realize that in the end people will see a digital photo.

I have a friend that, when I post a photo and I tell how it was done originally, he says always, «I could have done it pure digital!». The fact is that the photo softwares try to create effects similar to the old chemical photography, daguerreotypes, salt prints, lens effects, vignetting, all this were invented by chemical photography. There might be other strange effects pure digital but, because they don't resemble an old effect, will not be used consequently, remains a curiosity.

Well, but maybe in hundred years a more sofisticated technique will be able to simulate todays digital photo effects.

When you take a photo with a film camera, you are introducing some specific noise. The noise of the lens and sometimes of the shutter, the noise of the film, the noise of the developer and fixer. Then, if you scan the film, the scanner will pixelize the picture and introduce more digital noise. After this you will treat in a software and r«the software also introduces his own noise. Finally when you see the picture in a monitor, this one introduces also noise.

The digital noises may be kept so small that what we see is almost only the analogue original picture. Like when you make a photocopy and want that the photocopy looks close to the original. Because of this, its worth making old photography.

But in the future, maybe we will have a multipurpose digital camera that may be set to clone any analogue known camera. You have a menu where you can choose Minolta Maxxum 7000 with Sony Lens or Leica 3R with Summicron lens, etc.
