What would I see instead of pixels?

Postby moonmaid » Sat Jun 14, 2014 5:38 pm

I zoomed in on photos last night to correct red eye.
Got me wondering about photos taken from non digital cameras and photos not scanned into computer.

If I could zoom into them without using the computer. Maybe a microscope?
What kind of structure would I see? (no luck googling).

Depends whether it is raster or vector based ;) Fractal or other.

I think it depends on the context. Eventually you wont be looking at the picture any longer and instead be looking at the paper it is printed on.

Eventually you find that all pictures are just made up from old discarded keyboards.

I always think of these type of things by association Coastline Paradox but perhaps that is just me.

Oh nut! I can't understand that ;)

Very creative keyboard artist.

The graph on the wiki link seems out of wack with the coastline and text below (in case you created the page).

Photographic films and papers are made using a crystaline emulsion. In the old days (black and white) it was silver nitrate. I have no idea what chemicals they use for colour. As it's crystaline, you get a similar effect to pixels - similar, not the same.

So as you zoom in (or enlarge), you'll see "grain" beginning to appear. The further you enlarge, the less distinct the grain becomes until you eventually lose all definition and are faced with just a blurry blob.

Thanks Teleost. That's more understandable for someone like me. I popped in to find out about internet.
